| 05:26.32 | jbevren | hrm |
| 05:27.45 | joe_bleau | http://www.etoolsmiths.com/target-jtag-connector-pin-out.html ? |
| 05:28.45 | jbevren | not this one :( |
| 05:28.47 | jbevren | pin 6 is grounded |
| 05:31.38 | jbevren | layout's apparently like so |
| 05:31.39 | jbevren | 1 2 |
| 05:31.41 | jbevren | .. |
| 05:31.42 | jbevren | 15 16 |
| 05:31.46 | jbevren | pin 1 is reset |
| 05:31.48 | jbevren | pin 6 is gnd |
| 05:32.04 | jbevren | grounding pin 1 resets the board (but does nto short it out) |
| 05:33.09 | joe_bleau | I thought 10, 14, and 20 pins were common for JTAG, not 16. |
| 05:34.35 | jbevren | me too |
| 05:34.41 | jbevren | this has a 16pin header |
| 05:34.42 | jbevren | heh |
| 05:35.23 | joe_bleau | what's the main device on the scan chain? |
| 05:35.46 | jbevren | an unknown processor with black epoxy over it :( |
| 05:36.07 | jbevren | the device is a grandstream HT-488 |
| 05:36.30 | jbevren | I want to see if its possibly useful for anything before selling it off |
| 05:36.44 | jbevren | cause its firmware prevents proper operation in my voip system |
| 05:37.46 | joe_bleau | PowerPC COP instead of JTAG? |
| 05:37.57 | jbevren | the jtag signal group will be on adjacent pins you think? |
| 05:37.58 | jbevren | cop eh? |
| 05:45.30 | jbevren | ppc cop has vcc on 6 |
| 05:45.51 | joe_bleau | And what about your toy? |
| 05:46.50 | jbevren | hm? |
| 05:54.32 | jbevren | what about my toy? |
| 05:58.36 | joe_bleau | Back now...I meant to ask whether pin 6 was vcc on your toy |
| 05:58.41 | joe_bleau | Now I've scrolled the window back |
| 05:58.47 | joe_bleau | and saw that you have pin 6 as gnd. |
| 05:59.28 | jbevren | right |
| 06:01.31 | joe_bleau | Could it be an async serial port instead? |
| 06:01.54 | jbevren | with a reset switch eh? |
| 06:01.56 | jbevren | hrm |
| 06:02.50 | joe_bleau | Maybe, if it's a manufacturing test/program port? |
| 06:03.35 | jbevren | I know its a mfr test/program port.. its the only one of its type on the board heh |
| 06:03.39 | jbevren | I was hoping it was jtag |
| 06:03.41 | joe_bleau | (I've extended the BDM connector from 10-16 pins on my designs to add power, gnd, and an async port) |
| 06:04.18 | joe_bleau | Brute force it? |
| 06:05.47 | jbevren | heh |
| 06:05.54 | jbevren | I'll dig the scope out later |
| 06:06.05 | jbevren | if I get started with the scope I'll be up all night :) |
| 06:06.11 | joe_bleau | ID the input lines, then try all the combinations as a JTAG port |
| 06:06.44 | jbevren | that's.. 64 permutataions? |
| 06:06.45 | joe_bleau | Seems like you'd know it was correct when you can readback the state machine correctly. |
| 06:06.49 | jbevren | I cant remember how to calcuate it :) |
| 06:07.02 | joe_bleau | I'm thinking you'd do it in code. |
| 06:07.07 | joe_bleau | Wire all the inputs and outputs up |
| 06:07.15 | joe_bleau | and write a program to try all the combos |
| 06:09.37 | jbevren | nod |
| 06:09.42 | jbevren | at least one line freezes it (apparently) |
| 06:09.52 | jbevren | it pulls down without a short (2k resistor) |
| 06:10.08 | jbevren | if it doesnt register, the led blinks red, but stops when the line's grounded |
| 06:10.11 | jbevren | anyway |
| 06:10.17 | jbevren | I"ll mess with it later |
| 06:10.18 | jbevren | maybe |
| 06:11.25 | joe_bleau | Or work from the other direction...can you disassemble a firmware update and ID the cpu arch? |
| 06:11.49 | joe_bleau | That might give you a clue as to JTAG vs. COP or whatever |
| 06:12.31 | jbevren | ht-488.bin: raw G3 data, byte-padded |
| 06:13.00 | jbevren | btw, is opencores.org permanently off or ? |
| 06:17.40 | joe_bleau | Is raw G3 data, byte-padded some kind of fax data format?! |
| 06:17.48 | jbevren | I thought so :) |
| 06:17.52 | jbevren | must be a mis-identification |
| 06:18.12 | jbevren | ppc's start at 0 right? |
| 06:18.20 | jbevren | or do they use a vector like m68k |
| 06:18.21 | joe_bleau | No clue |
| 06:18.29 | jbevren | np |
| 06:18.54 | joe_bleau | I don't have a ppc binutils built to disassemble |
| 06:20.49 | jbevren | ah |

| 14:16.50 | jbevren_ | :D |
| 14:18.15 | prpplague | just out of curiosity, anyone here interested in a low cost arm7 dev board for hackers? |
| 14:18.35 | jbevren_ | how low-cost? |
| 14:18.59 | beeble | with ethernet? |
| 14:19.00 | jbevren_ | 8M flash, 16M ram, bus connector and gpio headers? :) |
| 14:19.19 | GPSFan | prpplague: greetings to you, master of the juiceboxen.. |
| 14:19.30 | prpplague | the whole kit including a case, dev motherboard (with prototype grid), main cpu board, and jtag dongle, $200 |
| 14:20.03 | prpplague | beeble: the first kit doesn't include ethernet but a 10baseT nic can be added for around $30.00 |
| 14:20.26 | jbevren_ | ah, so it has bus slots? :) |
| 14:20.32 | prpplague | jbevren_: naw |
| 14:20.46 | prpplague | jbevren_: you can add a standard packet wacker cs8900 |
| 14:20.58 | jbevren_ | beeble: btw, if it has a usb gadget port, you can network through it |
| 14:21.08 | jbevren_ | sure, its not eth, but it'll do the job |
| 14:21.09 | prpplague | jbevren_: no usb |
| 14:21.20 | jbevren_ | grr hehe |
| 14:21.24 | prpplague | jbevren_: but you could add a slave easy |
| 14:22.02 | prpplague | jbevren_: the whole kit is kinda like buying an advance parallax stamp |
| 14:22.09 | prpplague | jbevren_: you build what you want |

| 14:22.32 | jbevren_ | prpplague: ah. |
| 14:22.34 | prpplague | jbevren_: we have something similiar to that we will be selling |
| 14:23.05 | jbevren_ | sec, reading back |
| 14:23.09 | jbevren_ | had to fix a server issue hehe |
| 14:23.29 | jbevren_ | so how much ram/flash is on it? :) |
| 14:23.43 | prpplague | additionallly the usb slave can be added with something like this - http://www.dlpdesign.com/usb/2232m.shtml |
| 14:23.44 | jbevren_ | prpplague: ah, this card.. Ive seen it :) |
| 14:23.52 | jbevren_ | hehe |
| 14:23.56 | jbevren_ | the gp2x uses the 2322m |
| 14:23.57 | prpplague | jbevren_: 4m flash and 16mb ram is the base unit |
| 14:24.02 | prpplague | jbevren_: oh yea? |
| 14:24.07 | prpplague | jbevren_: wonder why |
| 14:24.09 | jbevren_ | I think so |
| 14:24.13 | jbevren_ | for usb slave operation |
| 14:24.21 | prpplague | jbevren_: doesn;t the samsung cpu already have slave and host operations? |
| 14:24.27 | jbevren_ | its not a samsung in the gp2x |
| 14:24.35 | jbevren_ | its some other brand, dual-arm-core chip |
| 14:24.39 | jbevren_ | 920 and 940 |
| 14:24.42 | prpplague | its not? |
| 14:24.50 | prpplague | oh i thought it was |
| 14:25.07 | prpplague | jbevren_: hmm, wonder if the code is available for the 2322 operations |
| 14:25.22 | prpplague | jbevren_: id like to see how close it came to the code i wrote |
| 14:25.41 | prpplague | oh and don't forget the cpu board has a sd/mmc slot on it |
| 14:26.02 | jbevren_ | ah |
| 14:26.07 | jbevren_ | its from Magic Eyes |
| 14:26.10 | jbevren_ | MMSP2 |
| 14:26.18 | prpplague | jbevren_: ?? |
| 14:26.23 | prpplague | the slave usb? |
| 14:26.26 | jbevren_ | the gp2x processor |
| 14:26.30 | prpplague | ahh |
| 14:26.40 | prpplague | jbevren_: so does it use the 2322 for usb? |
| 14:27.08 | jbevren_ | http://wiki.gp2x.org/wiki/Turning_on_and_off_the_USB_mass_storage_driver explains it |
| 14:27.12 | jbevren_ | it uses the net2272 driver, my bad |
| 14:27.23 | jbevren_ | the number is similar enough to throw me off :D |
| 14:31.08 | jbevren_ | :) |
| 14:31.17 | jbevren_ | url? ;-) |
| 14:31.36 | prpplague | oh freekin nice, this looks like what we should use instead of the ftdi chip |
| 14:31.45 | jbevren_ | it's usb2.0 |
| 14:31.46 | prpplague | http://www.plxtech.com/products/NET2000/NET2272/overview.asp |
| 14:31.49 | jbevren_ | small advantage :) |
| 14:32.15 | prpplague | well plus we have a driver the standard kernel tree |
| 14:32.23 | jbevren_ | nod |
| 14:32.33 | jbevren_ | the gp2x operates in usb blockdev mode using the 2272 |
| 14:33.03 | jbevren_ | oh, the EXT connector on the thing has USB pins as well, here's hoping its a host controller port I can stick a powered hub on |
| 14:33.06 | jbevren_ | (We'll see) |
| 14:33.29 | prpplague | ?? |
| 14:33.36 | jbevren_ | the gp2x |
| 14:33.39 | prpplague | jbevren_: the 2272 is just slave from what i read |
| 14:33.42 | jbevren_ | yeah |
| 14:34.22 | prpplague | jbevren_: ahh ok, i must be misunderstanding what you said then |
| 14:34.24 | jbevren_ | I'm hoping they stuffed the MagicEyes' host controller pins on there |
| 14:35.58 | prpplague | ahh |
| 14:36.35 | jbevren_ | anyway, back to the cheap arm board for hackers |
| 14:36.36 | prpplague | i have a ton hacking i need to do |
| 14:36.47 | prpplague | jbevren_: yep |
| 14:37.01 | jbevren_ | lol get the devkit for only $500 |
| 14:37.03 | jbevren_ | nothanks! |
| 14:37.13 | jbevren_ | I'll find something that uses it instead for $200:) |
| 14:37.22 | prpplague | hehe |
| 14:37.27 | prpplague | for the 2272 ? |
| 14:37.31 | jbevren_ | *cough gp2x cough* |
| 14:37.34 | jbevren_ | yeah |
| 14:37.46 | prpplague | hehe |
| 14:38.05 | jbevren_ | mine's allegedly scheduled for fedex overnight |
| 14:38.09 | jbevren_ | I'm hoping they actually shipped it |
| 14:38.11 | jbevren_ | grr |
| 14:38.11 | jbevren_ | :) |
| 14:38.33 | prpplague | jbevren_: thats kinda why we went with the ftdi design since it was available aleady in a prototype board |
| 14:38.51 | jbevren_ | cool |
| 14:39.15 | jbevren_ | did I miss your answer about ram/flash btw? |
| 14:40.28 | prpplague | 4mb flash, 16mb ram |
| 14:40.37 | jbevren_ | quite usable |
| 14:40.44 | prpplague | probably have a 8mb flash and 32mb ram available |
| 14:40.52 | prpplague | we haven't set those values in stone |
| 14:40.57 | jbevren_ | 4/16 will do simple tasks easily enough |
| 14:41.03 | prpplague | as the device can support a wide range of values |
| 14:41.07 | jbevren_ | heck, it worked for aeronix at 2/16 :) |
| 14:48.44 | jbevren_ | my friend and I were discussing a system targeted at gaming |
| 14:49.00 | prpplague | beeble: you require ethernet ? |
| 14:49.08 | jbevren_ | he knows nothing of arm, but went through the trouble of describing almost exactly waht an arm7 is when describing what he wants from the cpu :) |
| 14:49.15 | prpplague | jbevren_: yea, i've been thinking aobut that as well |
| 14:49.47 | beeble | prpplague: im just thinking about |
| 14:49.51 | jbevren_ | he wants a 640x400 display tho |
| 14:50.11 | prpplague | jbevren_: ahh |
| 14:50.15 | beeble | if we want to use arm7 too in our teaching lessons |
| 14:50.31 | prpplague | beeble: ahh, well this perfect for teaching |
| 14:50.57 | prpplague | beeble: i suspect that we will get alot of sales to schools |
| 14:51.43 | beeble | prpplague: its more software development |
| 14:51.52 | prpplague | ahh |
| 14:51.56 | prpplague | beeble: no hardware? |
| 14:52.39 | beeble | no, its embeddes systems programming with linux and a kernel programming lesson we are planning |
| 14:52.55 | prpplague | beeble: well this would work for that as well |
| 14:52.57 | jbevren_ | prpplague: Dunno how far I'd get though, I cant even seem to make a readback register in HDL :( |
| 14:53.06 | prpplague | jbevren_: hehe |
| 14:53.26 | jbevren_ | and opencores.org's been out for a while so I cant look for examples |

| 14:57.03 | prpplague | i was thinking a spi 802.11b |
| 14:57.16 | jbevren_ | or that |
| 14:57.24 | jbevren_ | I havent seen those available yet |
| 14:57.29 | jbevren_ | so I'm fairly skeptical :) |
| 14:58.02 | prpplague | beeble: why are yo teaching that? |
| 14:58.15 | prpplague | jbevren_: i have three on my desk |
| 14:58.29 | jbevren_ | where'd you get em? :D |
| 14:58.41 | prpplague | jbevren_: can;t say, there are under nda |
| 14:58.45 | beeble | prpplague: because we are a university ;) |
| 14:58.47 | jbevren_ | ah, samples eh? |
| 14:59.29 | prpplague | beeble: hmm, guess that proves my long held point that most colleges and universitys are out of touch with what they should be teaching |
| 14:59.43 | beeble | prpplague: we have the linux lessons to |
| 15:01.26 | beeble | the l4 is a try to do something "new" to get a lightweight kernel that can be certified and used for special applications |
| 15:02.15 | beeble | so, we have the embedded linux part for the learning stuff ppl can use in the realworld |
| 15:02.22 | beeble | and the l4 stuff for research |
| 15:15.33 | prpplague | ahh |
| 15:17.31 | beeble | uzi? |
| 15:18.10 | prpplague | http://uzix.sourceforge.net/index.php?page=intro&lang=us |
| 15:19.48 | beeble | ah |
| 15:20.04 | jbevren_ | yay? |
| 15:20.09 | jbevren_ | er wrong chan :) |
| 15:20.19 | jbevren_ | uzix seems pretty cool |
| 15:20.53 | prpplague | jbevren_: yea i had it running for gameboy |
| 15:21.24 | prpplague | jbevren_: i've started work on it for the the atmel arm7tdmi's that have both flash and ram |
| 15:22.19 | jbevren_ | nod |
| 15:22.23 | jbevren_ | I had a couple samples |
| 15:22.28 | jbevren_ | dunno what ever happened to em :) |

| 19:00.16 | prpplague | ZeZu: greetings |
| 19:00.21 | ZeZu | `lo |
| 19:00.29 | Genesis | yop prpp :) |
| 19:00.45 | ZeZu | you happen to know much about usb ? |
| 19:01.13 | prpplague | ZeZu: that there should be one more letter added so that it will be a proper four letter word |
| 19:01.38 | ZeZu | oh? |
| 19:01.43 | prpplague | hehe |
| 19:01.57 | prpplague | ZeZu: what area are you interested in? |
| 19:02.14 | ZeZu | one of the projects i work on is for the sega dreamcast, and its maple bus is very similar to usb, i'd like to make a coverter for it |
| 19:02.34 | ZeZu | i have all of the specs and hardware info for it |
| 19:02.54 | prpplague | ahh, well i've not gotten into the hardware for usb much |
| 19:03.17 | prpplague | ZeZu: you want to go from maple bus to usb host or slave? |
| 19:03.24 | ZeZu | host |
| 19:03.49 | prpplague | so you want the sega dreamcast to have a usb host interface? |
| 19:04.13 | ZeZu | err, no i was the pc to have a host interface for the dreamcast maple bus |
| 19:04.27 | ZeZu | so i can use the controllers and read the memory cards etc |
| 19:04.49 | ZeZu | eventually hook an extension from DC<->PC and use it for debugging |
| 19:04.53 | prpplague | ZeZu: you want to use the controllers and read the memory cards on the pc |
| 19:05.04 | ZeZu | yes |
| 19:05.07 | prpplague | ZeZu: ahh |
| 19:05.19 | ZeZu | that part is easy, i just need to get the hardware part figured out |
| 19:05.20 | prpplague | i'm not familiar with the maple bus |
| 19:05.37 | ZeZu | i am fairly familiar with it, but not usb really |
| 19:05.38 | prpplague | ZeZu: you have a url with some docs? |
| 19:05.45 | ZeZu | let me see |
| 19:06.13 | ZeZu | http://mc.pp.se/dc/controller.html |
| 19:07.16 | ZeZu | the "serial" link has a lot more info, but i have quite a bit more info in .doc format than that even, and i've completely RE'd other pieces of it |
| 19:07.56 | ZeZu | http://mc.pp.se/dc/maplewire.html is another |
| 19:09.35 | ZeZu | so its big endian 1mhz serial line protocol it looks like |
| 19:09.40 | prpplague | yea reading it now |
| 19:10.38 | prpplague | ZeZu: here is what you need to do a usb->maple converter - http://people.omnigroup.com/wiml/soft/pic/keyspan.html |
| 19:12.28 | ZeZu | o.O |
| 19:12.35 | ZeZu | that little adapter has some nice hardware in it |
| 19:12.54 | ZeZu | i suppose they cost more than your garden variety db9->usb |
| 19:13.10 | prpplague | nope, most cost aobut $20.00 |
| 19:13.14 | Genesis | anyone work on MES or CIM ? |
| 19:13.35 | Genesis | i mount a workgroup |
| 19:17.10 | ZeZu | hmm |
| 19:17.16 | ZeZu | usb is 3.3v ? |
| 19:17.21 | prpplague | ZeZu: 5v |
| 19:17.27 | ZeZu | oh, good |
| 19:19.57 | prpplague | ZeZu: with the keyspan you could hack something up in a week or so |
| 19:29.39 | jbevren_ | prpplague: found a yahoo store that sells the 2272 for $10 |
| 19:29.48 | jbevren_ | http://store.yahoo.com/plxtech/net2000chips.html |
| 19:30.03 | jbevren_ | bga and qfp formats |
| 19:30.09 | prpplague | its jsut the chip |
| 19:30.12 | jbevren_ | yeah |
| 19:37.44 | prpplague | i need something on a protoboard |
| 19:37.55 | prpplague | similiar to the dlpdesign board |
| 19:40.26 | jbevren_ | yeah |
| 19:41.50 | jbevren_ | its a 64pin qfp.. toss it on a schmartboard:) |
| 19:42.37 | prpplague | jbevren_: yea i need something i can sell |
| 19:42.42 | jbevren_ | nodnod |
| 19:42.53 | jbevren_ | if youre going to sell devboards, have em made and mounted ;-) |
| 19:43.02 | jbevren_ | I wouldnt mind stuffing my own headers on as long as the chip is mounted |
| 19:43.36 | prpplague | jbevren_: yea we have already got the design layed out for our version of the dlpdesign type pcb |
| 19:43.42 | jbevren_ | cool |
| 19:49.21 | ShortWave | Yesterday, I got to watch an SMD assembler machine in action. |
| 19:49.34 | ShortWave | That was interesting. |
| 19:49.34 | prpplague | ShortWave: fun to watch eh? |
| 19:49.45 | ShortWave | yeah it was cool |
| 19:50.08 | ShortWave | It put a whole board together in like a minute |
| 19:50.52 | ShortWave | Thing was quick |
| 19:52.07 | beeble | but the QA behind should be good |
| 19:52.23 | beeble | i got boards from our manufactuar with chips upside down |
| 19:52.31 | beeble | *er |
| 19:56.46 | ShortWave | that had to suck |
| 19:59.11 | beeble | yeah, it was just a single gate AND in the chipselect signal for the flash |
| 20:01.01 | beeble | and that was very funny, because writing only worked on half of the flash. so you cold coould boot the kernel but mountig of the filesystem was broken |
| 20:03.16 | beeble | but its still better to search for such errors then to solder it by hand ;) |
