| 04:06.50 | solar | <NovceGuru> anybody have a ~$50 linux SBC with ethernet and serial up their sleeve <-- anybody know what might fit the bill? |
| 04:08.02 | prpplague | $50 ethernet is pretty darn cheap and run linux |
| 04:08.31 | prpplague | wonder if he wanted a one time item or something he could repurpose |
| 04:12.10 | ds2 | in volume, that isn't to hard to do |
| 04:12.35 | ds2 | and even for one off, the webpal + NE2K clone fits under there with plenty of margin to spare |
| 04:13.34 | chouimat | blah |
| 04:13.43 | solar | I think the user is after just one board vs 1000 |
| 04:14.12 | solar | I can't think of anything in the sub 50 range. |
| 04:14.44 | prpplague | the closet you are going to get is an avr32 ngw board |
| 04:14.52 | chouimat | prpplague: great board |
| 04:14.57 | prpplague | and iirc thats $80 |
| 04:15.06 | chouimat | + shipping :) |

| 14:03.43 | prpplague | GPSFan: not too bad, busy weekend hacking |
| 14:03.54 | prpplague | GPSFan: did alot of stuff, nothing complete though :( |
| 14:03.55 | GPSFan | progress on the didj? |
| 14:04.19 | prpplague | GPSFan: i tried about 1/2 of the 120 possible combinations of jtag pins with no success |
| 14:04.28 | GPSFan | ;>(( |
| 14:04.38 | prpplague | GPSFan: guess i need to wire up an atemga48 to do jtag identification |
| 14:05.19 | GPSFan | prpplague: if you are going to continue in this line of work, it might come in handy.. |
| 14:05.24 | prpplague | GPSFan: yea |
| 14:05.53 | prpplague | GPSFan: was thinking i might back off of the didj dev for a week or so until i can get a solid jtag identifier working |
| 14:06.14 | prpplague | GPSFan: test it with several of the boards i have that i have known working jtag pinouts on |
| 14:06.27 | GPSFan | did you find the serial port? |
| 14:06.49 | prpplague | GPSFan: on top of that, i'm doing some design work for solar, some openocd coding for the beagle, and i still have the M8050 to finish |
| 14:07.04 | prpplague | GPSFan: nope, i suspect it is available on the cartridge connector |
| 14:07.11 | GPSFan | yikes, no time even for a beer.. |
| 14:07.12 | prpplague | GPSFan: but i lack pinouts of the processor |
| 14:07.22 | prpplague | GPSFan: so it is going to be a tough deal to find |
| 14:07.59 | prpplague | GPSFan: "no time even for a beer.." or to beat the kids or go to the nudie bar |
| 14:08.06 | prpplague | hehe |
| 14:08.22 | GPSFan | gotta have your priorities straight. |
| 14:08.30 | prpplague | indeed |
| 14:08.42 | prpplague | GPSFan: done anymore with the z2? |
| 14:09.40 | GPSFan | nah, had a cold the last week, the wife has been away too, so just grinding on farm stuff, sniffling, and coughing... |
| 14:10.03 | prpplague | ahh gotcha |
| 14:10.10 | prpplague | GPSFan: getting ready for the big freeze? |
| 14:11.07 | GPSFan | there is a chill in the air, to be sure. we usually have a long fall, well into Nov, before we get too much snow |
| 14:12.07 | g1powermac_PB | wishes we had halfway decent spring and fall |
| 14:12.18 | GPSFan | the z2 is sitting here on my desk with jtag attached, just waiting for me to get off my butt and step through the blob init code. |
| 14:12.20 | g1powermac_PB | it tends to go straight into summer and winter out here |
| 14:12.45 | g1powermac_PB | like one day 90F next week is 40F |
| 14:13.00 | prpplague | GPSFan: yea, i lost interested in the z2 |
| 14:13.12 | prpplague | GPSFan: wasn't much i found interesting in the design |
| 14:13.27 | g1powermac_PB | needs to get back to work on his zipit |
| 14:15.11 | GPSFan | prpplague: if I had a specific project for it, or something that really needed doing, I'd be more interested, the z1 was a challenge, because zipit did everything in the zipit app. but the z2 uses linux for most everything, so it's sort of ho--humm. |
| 14:15.29 | prpplague | GPSFan: yea |
| 14:15.52 | prpplague | GPSFan: the only item that is still interesting me on the didj is the processor and jtag identification |
| 14:16.26 | GPSFan | and their code is crap, and with most of the folks on #zipit being OE'centric, I'm sort of the odd man out. |
| 14:16.32 | prpplague | i need to clean my desk, do some battery tests today, and see if i can find time to the atmega48 jtag identifier |
| 14:16.40 | prpplague | GPSFan: yea |
| 14:17.02 | prpplague | GPSFan: OE has it's uses, i just don't find it all that usefull for a device like the z2 |
| 14:17.34 | g1powermac_PB | GPSFan: yea, its annoying, really its just me and you doing non OE stuff on the zipit |
| 14:17.35 | GPSFan | prpplague: most of them still don't have the wireless working, they just build and rebuild the OE stuff, hoping that it will magically work the next time. |
| 14:18.39 | prpplague | GPSFan: yea, that kind of stuff is very annoying |
| 14:18.40 | GPSFan | prpplague: there was one guy that got a good start on porting apex, then he just vanished a couple of weeks ago. |
| 14:18.52 | prpplague | GPSFan: hmm |

| 15:59.58 | MothaWork | near as I can tell, it's never even pinging it |
| 16:07.41 | g1powermac | ok, digging fence posts in limestone country sucks |
| 16:08.16 | g1powermac | them parents of mine got me doing lots of physical stuff before my surgery as I won't be able to do this stuff for at least a month after |
| 16:08.27 | kergoth`work | digging fence posts sucks in general |
| 16:08.51 | prpplague | solar: ping |
| 16:08.52 | g1powermac | yea, but when you add in gravel and largish chunks of limestone, it adds to the suckage |
| 16:08.53 | adyer | g1powermac: lol, I once had to dig a corner post hole, about 5 feet down through what used to be a gravel road (in summer, in TN) :-( |
| 16:09.07 | g1powermac | adyer, oh dear |
| 16:09.52 | kergoth`work | the only time i had to dig them was a place where the water table was too high, a small hole becomes a giant pit awfully quickly |
| 16:09.59 | kergoth`work | no fun |
| 16:10.03 | g1powermac | ahh, yea |
| 16:10.09 | g1powermac | I've dealt with that in the past |
| 16:10.27 | g1powermac | living only a few blocks away from the bay/ocean |
| 16:10.28 | adyer | g1powermac: I had a 6 ft iron bar with a chisel like blade on the end to help, gloves were polished smooth by the end of the day |
| 16:11.05 | g1powermac | adyer, man, could've used that just 10 mins ago with the large chunk of limestone I had to remove |
| 16:12.07 | g1powermac | thinks he's gonna need a new shovel after he's done |
| 16:13.04 | RobotGuy | sends g1powermac a post hole digger |
| 16:13.25 | adyer | g1powermac: that hole made me not want to be a farmer :-) |
| 16:13.28 | g1powermac | and most likely I'm going to have to dig these holes deeper once we find out how big the fence posts are going to be |
| 16:14.15 | g1powermac | RobotGuy, heh, a motorized post hole digger would prolly explode killing everyone in site in this soil ;-) |
| 16:14.31 | g1powermac | adyer, can imagine |
| 16:14.34 | adyer | g1powermac: rock drill + explosives :-) |
| 16:14.45 | g1powermac | ahh, now thats a fun combination :-) |
| 16:15.09 | g1powermac | time to take a ride to indiana to buy some 1/4 sticks of dynamite ;-) |
| 16:15.28 | RobotGuy | makes not to NEVER give g1powermac things that go BANG or BOOM.. |
| 16:15.40 | g1powermac | bwahahahaha |
| 16:15.42 | g1powermac | ;-) |
| 16:15.58 | g1powermac | actually, I'm not that bad, had a friend of mine that was worse |
| 16:16.12 | g1powermac | he then went into the navy to play with the really big explosives ;-) |
| 16:16.23 | adyer | g1powermac: I read an article about the school of mines at Mizzou - they have a program all about using explosives for mining. |

| 16:16.58 | g1powermac | RobotGuy, ouch |
| 16:18.05 | g1powermac | adyer, you know, I wouldn't doubt that there is something like that here in this state |
| 16:18.13 | g1powermac | with all the coal mines we have |
| 16:21.32 | g1powermac | ah well, got lots of different things I'll be planting in the early spring once this fence is up and we make the large raised beds |

| 16:26.24 | dbtid | can someone give me a little push? |

| 16:26.49 | RobotGuy | gives dbtid a little push. :) |
| 16:26.59 | chouimat | morning .... |
| 16:27.17 | prpplague | dbtid: zImage ? |
| 16:27.47 | dbtid | uImage |
| 16:27.56 | dbtid | IIRC uImage == zImage + u-boot header |
| 16:28.06 | dbtid | RobotGuy: i knew someone would do that :P |
| 16:28.24 | RobotGuy | grins |
| 16:28.26 | prpplague | dbtid: yea |
| 16:28.42 | prpplague | dbtid: i guess i should document that too |
| 16:28.52 | dbtid | document what? why you? |
| 16:29.13 | prpplague | dbtid: because not too many people reverse process a kernel image |
| 16:29.21 | dbtid | i'm doing a make V=1 uImage right now |
| 16:29.24 | prpplague | dbtid: only those of use who are hacking |
| 16:29.42 | dbtid | indeed |
| 16:29.45 | prpplague | dbtid: first you'll need to remove the 64byte uboot header |
| 16:29.59 | dbtid | no problem... hexdump -s 64 |
| 16:30.01 | prpplague | dbtid: then you'll need a program included with the linux kernel under scripts |
| 16:30.03 | RobotGuy | If you just can't resist purchasing every new gadget that comes out, you might be a hacker.. |
| 16:30.06 | dbtid | oh |
| 16:30.16 | prpplague | dbtid: binoffset.c |
| 16:30.26 | prpplague | dbtid: you can use it from any kernel from around 2.6.20 |
| 16:30.47 | dbtid | i will give it a try |
| 16:30.48 | dbtid | thanks |
| 16:30.48 | prpplague | dbtid: binoffset will tell you where the compressed image starts |
| 16:30.54 | g1powermac | RobotGuy, meh, its not just the latest gadgets ;-) |
| 16:31.01 | prpplague | dbtid: once you locate the offset you will need to decompress it |
| 16:31.08 | RobotGuy | Well, time to leave to go get my spinal tap. |
| 16:31.14 | g1powermac | RobotGuy, good luck |
| 16:31.16 | dbtid | binoffset says it locates a pattern. what's the pattern? |
| 16:31.19 | solar | yeahgood luck |
| 16:31.23 | RobotGuy | g1powermac: You're an addicted hacker. :p |
| 16:31.32 | g1powermac | RobotGuy, nah, I'm just insane ;-) |
| 16:31.36 | CosmicPenguin | RobotGuy: just remember, it goes to 11 |
| 16:31.47 | g1powermac | prpplague can attest to that ;-) |
| 16:32.16 | prpplague | dbtid (dd ibs="$off" skip=1 count=0 && dd bs=512k) <"$image" 2>/dev/null | zcat >"$TMPFILE" |
| 16:32.58 | dbtid | there's going to be an issue using dd because the image resides on a NAND flash; nanddump can do it for me, though. |
| 16:33.11 | prpplague | dbtid: ?? |
| 16:33.22 | dbtid | when there are bad blocks on a NAND flash, dd pukes. |
| 16:33.39 | prpplague | dbtid: you don't have a copy of the uImage on your dev pc? |
| 16:33.53 | dbtid | yes, i do; all of what I'm doing is going to be done on the target. |
| 16:34.04 | prpplague | uh, ok, why? |
| 16:34.13 | dbtid | if i do a field update, FAA requirements say that I have to be able to verify that what's on the NAND now matches what's expected. |
| 16:34.22 | dbtid | so there's a file that is sent along with the field update |
| 16:34.32 | dbtid | so i use nandwrite to dump the new image to nand |
| 16:34.42 | dbtid | then i have to read it back and pull the version out of the file |
| 16:35.08 | dbtid | it's all moderately insane |
| 16:35.15 | prpplague | dbtid: why not simply add the version information to the 64byte uboot header? |
| 16:35.31 | dbtid | indeed. |
| 16:35.35 | dbtid | why not? |
| 16:35.37 | dbtid | hmm |
| 16:35.38 | adyer | dbtid: or calculate an md5 hash over the whole thing |
| 16:35.49 | dbtid | well, there's issues with that, as well. |
| 16:35.53 | prpplague | dbtid: the uboot header already has a hash in it |
| 16:36.10 | prpplague | dbtid: i'd simply add the version stuff to the header, that is what it is there for |
| 16:36.12 | dbtid | there's issues with using hashes because of the partial block NAND problem |
| 16:36.18 | dbtid | i'll look into that |
| 16:36.19 | dbtid | thanks |
| 16:43.17 | dbtid | ok, this puzzles me a lot |
| 16:43.24 | dbtid | inside arch/arm/boot/Makefile |
| 16:43.26 | dbtid | it calls |
| 16:43.33 | dbtid | $(call if_changed,uimage) |
| 16:43.45 | dbtid | that's what ends up invoking scripts/mkuboot.sh |
| 16:44.02 | dbtid | problem i haven't been able to figure out is how to determine what uimage is as a target? |
| 16:44.47 | dbtid | oh wait |
| 16:44.55 | dbtid | there's a "cmd_uimage" |
| 16:45.02 | dbtid | i bet that's what's being invoked |
| 16:45.12 | dbtid | i'd have to put the number in there somehow |
| 16:47.39 | prpplague | dbtid: yea there should be a section for arguments |
| 16:48.07 | dbtid | cmd_uimage = ... |
| 16:48.14 | dbtid | then i just have to add all the grepping |
| 16:49.28 | dbtid | this is painful |
| 16:50.28 | prpplague | dbtid: alot less painful that having all the decompressing of the kernel |
| 16:50.33 | dbtid | true |
| 16:55.54 | dbtid | ok, well, i've hacked the Makefile in arch/arm/boot and added a 'getmlxver' script that will pull the info out. |
| 16:55.59 | dbtid | now hopefully my Makefile mods are correct |
| 16:56.19 | dbtid | we shall see |
| 16:56.40 | dbtid | nope |
| 16:58.25 | dbtid | closer |
| 16:58.32 | dbtid | i wish i knew of a cleaner way to do this |
| 16:58.56 | dbtid | i mean, inserting my version |
| 16:59.22 | dbtid | well it worked |
| 16:59.36 | dbtid | i know have "Image Name: Linux-2.6.35 MLX ....." |
| 16:59.40 | dbtid | it's a good start |

| 17:16.12 | g1powermac_PB | James Gillies, the LHC head of public relations says he's gotten calls from people literally sobbing and asking him to halt the project. He states, "They phone me and say: ?I am seriously worried. Please tell me that my children are safe.?" |
| 17:16.21 | g1powermac_PB | think of the children! |
| 17:16.47 | prpplague | hehe |
| 17:17.38 | g1powermac_PB | He states, "There are a number who say: 'You are evil and dangerous and you are going to destroy the world.' |
| 17:17.51 | g1powermac_PB | hmm, I get that every other day ;-) |
| 17:18.24 | prpplague | hmm, is "twit" considered a curse ? |
| 17:18.57 | CosmicPenguin | I dunno - when I read it, I thought it was using a different vowel |
| 17:19.05 | g1powermac_PB | not in my vocabulary |

| 19:41.23 | solar | CosmicPenguin: it was a bribe from my boss for working over the weekend |
| 19:41.40 | solar | he added in a 4G SDHC card too. |
| 19:42.02 | solar | no real keyboard however. So best that could be done is make about the equiv of the OM |
| 19:43.21 | solar | ahh spiffy. just checked online. silly thing is a ~600-900 phone |
| 20:20.20 | prpplague | solar: yea thats a nice phone |
| 20:21.15 | prpplague | solar: i had apex up and running on it and was doing some work with it when laforge got all agressive about "dividing efforts" and that i should be working on uboot |
| 20:29.18 | MothaWork | oh, this has got to be the dumbest bug ever |
| 20:29.24 | MothaWork | and I'm still not sure why it exists |
| 20:29.33 | prpplague | MonMotha: do tell |
| 20:30.48 | MothaWork | prpplague: somehow, after the BSP init code ran (and muxed all the IOs for the ethernet device), the IOs got remuxed before the driver probe code ran as GPIO |
| 20:30.55 | MothaWork | so the driver had no PHY to talk to |
| 20:31.04 | prpplague | MothaWork: ahh, btdt |
| 20:31.25 | prpplague | MonMotha: thats why i use devmem, good tool to double check mux settings after startup |
| 20:32.18 | MothaWork | I still haven't found where it's getting remuxed |
| 20:32.35 | MothaWork | I just copied and pasted all the peripheral muxing for the ethernet from the BSP code into the driver for now |
| 20:32.36 | MothaWork | it works, at least |
| 20:34.22 | adyer | wonders what the most 'overloaded' pin muxing setup is. super-io chips come to mind |
| 20:36.53 | MothaWork | stupid pin muxing... |
| 20:37.10 | MothaWork | the pin muxing on this chip is just downright annoying |
| 20:37.33 | adyer | MothaWork: which chip? |
| 20:37.42 | MothaWork | you want 24-bit LCD? Can't use ethernet in MII mode. Want two external interrupts? Say goodbye to CAN! Perhaps you wanted SDRAM on the second bus? Bye Bye ethernet. |
| 20:37.46 | MothaWork | adyer: AT91SAM9263 |
| 20:38.09 | MothaWork | there's GPIOs with no alternate function even though some functions are muxed together in annoying ways |
| 20:38.33 | MothaWork | there are only two external interrupts (not counting FIQ which doesn't seem to work in Linux), and both are muxed with something (one with CAN, which is a major function) |
| 20:40.03 | MothaWork | I would have really, really liked to have 3 on this board, but I got by with 2 |
| 20:48.34 | roxfan | maybe you should switch then |
| 20:49.10 | prpplague | roxfan: you have a hammer board? |
| 20:49.23 | roxfan | nope |
| 20:49.56 | roxfan | i have an lm3s-811 eval kit |
| 20:50.08 | roxfan | and a few various devices |
| 20:50.14 | prpplague | roxfan: what was it that you designed the jtag finder for ? |
| 20:50.27 | MothaWork | roxfan: this processor has the selection of major features we need, and, um, I've got production hardware at this point :) |
| 20:50.27 | roxfan | lm3s-811 |
| 20:50.28 | MothaWork | not switching |
| 20:50.39 | roxfan | which is a luminary cortex-m3 |
| 20:50.49 | MothaWork | the processor as a whole is fairly nice; it just has a lot of minor annoyances |
| 20:51.00 | MothaWork | and really, you'll get that to an extent on almost any "big" processor |
| 20:51.04 | roxfan | http://www.luminarymicro.com/products/ekk-lm3s811_evaluation_kit.html |
| 20:51.16 | roxfan | production eh |
| 20:51.24 | prpplague | roxfan: sorry i mean what device were you trying to find jtag on |
| 20:51.26 | roxfan | i guess got to stick with it then |

| 20:56.36 | roxfan | not really |
| 20:56.42 | roxfan | just this once basically |
| 20:56.50 | prpplague | ahh ok |
| 20:57.16 | prpplague | i've got a jtag project in the works, so i'm looking around for some developers |
| 20:57.51 | MothaWork | ds2: seconded |
| 20:58.09 | MothaWork | ds2: maybe in several years, but it |
| 20:58.12 | MothaWork | it's too early |
| 20:58.23 | MothaWork | the lead free solders are getting better, but they still suck |
| 20:59.37 | ds2 | is there a work around other then heating a pin longer to rework a rohs board? |
| 21:00.13 | prpplague | really disappointed with the SFLC's professionalism towards people who report violations |
| 21:01.33 | prpplague | doubt i'll report anything to them again |
| 21:01.42 | MothaWork | ds2: higher iron temps, if the PCB and part can take it |
| 21:01.58 | adyer | ds2: does it need to still be RoHS when you're done? :-) (oh, and use flux!) |
| 21:02.12 | MothaWork | that is true. Getting some leaded solder in there does amazing things |
| 21:02.26 | ds2 | adyer: nope. I am suffering cuz of some imbiciles in brussels decided to go off |
| 21:03.06 | ds2 | the pads have a layer of rohs solder on there and I still need to heat it up so my solder will mingle with the pad |
| 21:03.12 | ds2 | copper would be nice but.. |
| 21:06.17 | adyer | ds2: it's not going away (just like SMT, BGA, and no clean stuff before it), you just have to suffer through until it gets better. |
| 21:07.14 | MothaWork | SMT/BGA and no-clean all had very good reasons |
| 21:07.19 | MothaWork | density and assembly cost |
| 21:07.45 | MothaWork | RoHS is all about some phantom issue that can just as easily be solved via proper recycling without messing up the reliability of electronics |
| 21:07.54 | MothaWork | yes, the new stuff grows tin whiskers, even though they say it does not |
| 21:20.48 | prpplague | sflc people are real jerks |
| 21:22.56 | roxfan | post it on slashdot, maybe you can start a big flame war :) |
| 21:23.28 | prpplague | roxfan: no need for that, just won;t ever deal with them again |
| 21:24.39 | roxfan | well, to warn others? |
| 21:25.22 | prpplague | roxfan: naw, i expect most people just email them the violation info and thats the end of it |

| 21:56.48 | prpplague | roxfan: ahh, isn't that just an early implementation of unapproved cJTAG ? |
| 21:56.58 | roxfan | don't know |
| 21:57.16 | prpplague | makes a not to check |
| 21:57.22 | prpplague | note even |
| 21:57.23 | adyer | prpplague: I thought that ARM proposed their debug standard for 1149.7 but the cjtag stuff got approved instead |
| 21:57.59 | prpplague | adyer: i've not read in detail, but that was the gist of it |
| 22:00.48 | roxfan | In brief, the key to the two-pin operation is the elimination of the original data lines (TDI/TDO) and the bi-directional transmission of serialized data over the TMSC line. |
| 22:00.53 | roxfan | yeah, sounds like swd |
| 22:03.28 | roxfan | cortex-m3 got div instruction btw... even A8 doesn't have it :) |
| 22:05.03 | prpplague | yea, i'm just now diving into A8 stuff for this jtag dev |
| 22:05.17 | MonMotha | adyer: doesn't look too bad. It'll make the pods a little more complicated from the looks, but could simply/lower cost of the production devices (DUT from POV of JTAG) |
| 22:06.24 | prpplague | did they annouce some processors that support the cJTAG yet? |
| 22:07.06 | prpplague | hmm, one if they have a retro fit irc that will convert old jtag to cJTAG |
| 22:12.59 | prpplague | heads home for the day |

| 22:26.25 | g1powermac_PB | hey prpplague |
| 22:28.51 | ds2 | tip of the day - always inspect the markings on your parts and verify with a datasheet prior to assembly. 74LCX04 (part supplied by vendor) only go down to 2.3V where as a 74LVC04 (part order) goes down to 1.3V :( |
| 22:29.15 | g1powermac_PB | ahh fun |
| 22:29.18 | ds2 | that becomes kind of important in a 1.8V circuit! |
| 22:29.25 | g1powermac_PB | just a bit |
| 22:29.54 | ds2 | the troublesome part is it may just work during initial testing but fail in odd ways later :( |
| 22:30.29 | g1powermac_PB | more fun |

| 23:02.13 | prpplague | ds2 doh |
| 23:02.17 | prpplague | ds2 btdt |
| 23:20.00 | prpplague | ho ho hum |
| 23:20.05 | prpplague | are we having fun yet? |
| 23:21.21 | solar | Almost.. |
| 23:27.12 | g1powermac_PB | meh, got a load of fence stuff I need to work on tomorrow |

| 23:28.35 | MonMotha | ds2: you know that's REALLY annoying when you get stuff in moisture barrier packing that you can't see through and can't open to inspect |
| 23:28.56 | prpplague | i fired off an email to leapfrog earlier |
| 23:28.59 | MonMotha | I had Digi-Key send me a bunch of 128k micros w/o crypto HW when I ordered 256k micros w/ crypto acclerators |
| 23:29.11 | MonMotha | didn't notice until I got the boards back from assembly |
| 23:29.17 | g1powermac_PB | ahh fun |
| 23:29.40 | MonMotha | at the time, our code fit in 128k (doesn't now), so we could at least use them for our demo we had to give, but that sucked |
| 23:30.36 | g1powermac_PB | luckily it was pin compatible |
| 23:31.12 | prpplague | we had a whole batch of cradles that the assembly house somehow swapped C1/C11 as well as R1/R11 |
| 23:31.22 | MonMotha | g1powermac: indeed |
| 23:31.45 | MonMotha | ordered a SAM7XC256, got a SAM7X128 |
| 23:32.11 | g1powermac_PB | ah well, time to unload the fence stuff |
| 23:32.17 | g1powermac_PB | plus the bags of concrete |
| 23:33.42 | prpplague | solar all this jtag stuff makes my head hurt |
