| 02:07.12 | solar | evening |
| 02:07.24 | prpplague | solar hey bud |
| 02:07.35 | solar | feels good to relax |
| 02:07.51 | prpplague | solar whats cookin? |
| 02:07.58 | prpplague | is in the dog house |
| 02:08.08 | solar | ohhh |
| 02:08.16 | prpplague | spilled a glass of beer on the couch, boss lady is pissed |
| 02:08.50 | solar | not much. was just with one of gentoo's docs guys about sending him my beagle so it can get the work over and be documented properly. |
| 02:09.03 | solar | and I'll do any handholding he needs in training |
| 02:09.13 | prpplague | ahh |
| 02:09.31 | prpplague | solar yea both my beagles have been in the box doing nothing |
| 02:09.41 | prpplague | solar the beagle just isn;t that interesting to me |
| 02:09.58 | solar | it's a cute device. But I can cause usb resets far to easy with my work habits |
| 02:10.30 | solar | I don't know how to be nice to a device. It's expected to work or queue data |
| 02:11.06 | prpplague | indeed |
| 02:12.22 | solar | hacking on anything new these days? Or still stuck in FT CE.dev ? |
| 02:12.31 | solar | ft = fulltime |
| 02:13.17 | prpplague | yea mostly learning ce dev, but i got a nice bump today from a potential job |
| 02:13.25 | prpplague | we'll see how it goes |
| 02:13.51 | solar | oddly enough I was on your linked in page not but 30mins before you showed up |
| 02:13.59 | prpplague | oh? |
| 02:14.04 | prpplague | wonders why |
| 02:14.37 | solar | a friend was saying he did not know much about arm compared to most. I was explaining there are not many gurus in the world |
| 02:14.42 | solar | and I only know a few |
| 02:15.01 | solar | so I had to go peek what defines an arm guru |
| 02:15.09 | prpplague | hehe |
| 02:15.14 | prpplague | feels honored |
| 02:15.37 | solar | I think it's the bringing up drives from nothing. |
| 02:15.58 | solar | s/drives/devices/ |
| 02:16.09 | prpplague | thats the "thrill" for me |
| 02:16.41 | solar | you actually remind me quite a bit of the guy who does the PaX kernel patches |
| 02:17.05 | prpplague | till you get jtag, bootloader, and a kernel booting, as far as i am concerned, it's a big piece of silicon and copper |
| 02:18.17 | prpplague | solar well i have a potential for a nice job in the DFW area doing kernel dev |
| 02:18.28 | prpplague | solar hopefully it will play out right |
| 02:18.34 | solar | for arm? |
| 02:18.42 | prpplague | yea |
| 02:18.55 | prpplague | and no i can't say for who |
| 02:19.01 | solar | I would not ask |
| 02:19.19 | solar | you are taking risk even talking about the idea of looking for a new job in public |
| 02:19.20 | prpplague | but it will be a dandy if i can land it |
| 02:19.40 | prpplague | solar at this stage, i have no worries about AML |
| 02:20.09 | solar | got enough saved to feed the young ones for 6-18 months? |
| 02:20.30 | prpplague | hehe, my father left me a tidy sum |
| 02:20.49 | prpplague | i'm finalizing his estate now, should be done by the end of july |
| 02:20.55 | solar | then.. Do a favor to us all. |
| 02:21.02 | prpplague | ??? |
| 02:21.07 | solar | take 3 months off from having a job :) |
| 02:21.18 | prpplague | hehe, am i that bad off/ |
| 02:21.20 | prpplague | hehe, am i that bad off/\ |
| 02:21.21 | prpplague | ? |
| 02:21.33 | solar | you will get 1 month of drinking in. 1 months of follow up. 1 month of new ideas |
| 02:21.47 | prpplague | hehe |
| 02:22.16 | prpplague | i'll be alot better off when i get my fathers estate finalized |
| 02:22.25 | solar | take the kids to scope out the beech bar idea and putting a local to work? |
| 02:22.43 | prpplague | hehe |
| 02:22.54 | solar | start a chain! |
| 02:23.22 | prpplague | yea well, that;s on the agenda but it will be a while |
| 02:23.35 | ds2 | heh |
| 02:24.28 | ds2 | grumbles at ATSC |
| 02:24.56 | prpplague | solar gonna buy up about 10 M8050's and about 20 of the hammer kits |
| 02:25.06 | prpplague | solar see who i can give them away to |
| 02:25.07 | solar | prpplague rum? Another way to put others to work and save some $$ on the stuff to sell on the beach. What could make you special |
| 02:25.23 | solar | you are going to buy them? |
| 02:25.28 | prpplague | solar yea |
| 02:25.33 | solar | why? |
| 02:25.52 | ds2 | what's the resolution on the M8050? |
| 02:25.52 | prpplague | solar just because i want to |
| 02:26.19 | prpplague | ds2 the lcd is just a 320x240 right now, but we have a vga display that will be available soon |
| 02:26.29 | ds2 | oh low res stuff |
| 02:26.36 | prpplague | yea |
| 02:26.41 | ds2 | if it is 800x480 or better... |
| 02:26.43 | prpplague | about 5 years behind |
| 02:26.56 | prpplague | thats the whole problem with AML |
| 02:26.57 | ds2 | a ruggedized hand held could be nice |
| 02:27.06 | prpplague | they are 5-10 years behind |
| 02:27.41 | ds2 | start a competitor that is more in tune with the times |
| 02:27.49 | prpplague | *cough* maybe |
| 02:28.17 | prpplague | ds2 gotta get some things squared away first |
| 02:28.24 | prpplague | ds2 we'll see where things go |
| 02:28.31 | ds2 | prpplague: =) |
| 02:30.09 | prpplague | solar my father was a very charitable man, he believe in education, science and learning, i kind of owe it to him to use some of his estate money to make some stuff like the hammer and 8050 available to developers that might be able to afford them |
| 02:31.28 | ds2 | thesedays most folks don't care about any of that |
| 02:31.35 | solar | the 8050 is a very unique device. I think the real magic that could be done with them would with the ISV's |
| 02:32.05 | prpplague | solar indeed |
| 02:32.06 | solar | who write software for the barcode scanning/magstripe etc. |
| 02:32.12 | prpplague | yea |
| 02:32.24 | solar | that is what that platform is all about anyway |
| 02:32.35 | ds2 | how is the mag strip reader wired up? bunch of GPIO's direct from a comparator on the mag head? |
| 02:33.13 | solar | it's hard to get oss devs to get hyped up about such things imo at the same time cuz that's usually the kind of a thing a company needs vs the hacker in his home |
| 02:33.22 | prpplague | ds2 the mag head as an asic which decodes and buffers the bits, you get an irq and then you clock out the data |
| 02:33.35 | prpplague | solar yea |
| 02:33.38 | ds2 | prpplague: oh... isn't that... uh... overkill? |
| 02:33.49 | prpplague | ds2 ?/ |
| 02:33.50 | prpplague | ?? |
| 02:33.55 | prpplague | overkill? |
| 02:34.02 | ds2 | yeah...an asic to do that |
| 02:34.22 | ds2 | I was doing that as a class project using a 16MHz HC11 with a ton of cycles to spare |
| 02:34.24 | prpplague | ds2 the asic is part of the mag head, it;s ordered as a single part |
| 02:34.26 | wmat | prpplague: why do you have to buy up the kits? |
| 02:34.30 | ds2 | I see |
| 02:34.48 | prpplague | wmat why would you have to buy the kits? |
| 02:34.55 | solar | it sounds like he wants to do a good deed |
| 02:35.01 | wmat | oh, i see |
| 02:35.10 | wmat | i thought they were trashing them or something silly |
| 02:35.13 | prpplague | ds2 there is only like $0.20 difference in cost |
| 02:35.34 | prpplague | wmat naw, i get a little discount, but not much |
| 02:35.49 | ds2 | prpplague: gotcha... all I know about mag strips was using a part from MPJA + the 2600 article |
| 02:36.15 | wmat | prpplague: you should start a competitor |
| 02:36.21 | solar | it reads my credit cards quite well. A bit scary even |
| 02:36.26 | prpplague | ds2 yea the asic is one of the bonus things that the manufacturers are providing to make it easier to intergrate |
| 02:36.44 | ds2 | prpplague: it is a no brainer to directly process raw data |
| 02:37.20 | ds2 | solar: tried your driver license? |
| 02:37.24 | prpplague | ds2 yea we've done the decoder portions at AML for years, it was worth the extra $0.20 for the asic |
| 02:37.32 | solar | prpplague: what the device lacks is a pistol grip. The res is fine for any task one might have at hand imo |
| 02:38.18 | prpplague | solar we have a pistol grip for it, management doesn't want to release it, they think that by adding a pistol grib it will devalue future products that are bigger |
| 02:38.42 | solar | ds2: I'm still using my GA id |
| 02:38.59 | ds2 | solar: oh. |
| 02:39.27 | ds2 | if it had a RFid (multi band) and smart card reader... |
| 02:39.45 | prpplague | ds2 yea my original design had rfid and smart card support |
| 02:40.16 | ds2 | prpplague: I think there is a value in having a semiuniversal tracking system |
| 02:40.26 | *** join/#edev methril|work (n=Methril@213.27.233.98) |
| 02:40.29 | ds2 | esp. for the slightly smaller guys whocan't get all their suppliers to standardize |
| 02:40.33 | solar | prpplague: not every management decision is a good one |
| 02:40.47 | prpplague | funny thing is, the 8050 was initially a design to field test the technology we were going to use for the M8000, and before i knew it, one of our engineers had presented my design as his to management |
| 02:41.22 | prpplague | the 8050 wasn't even intended as a commercial product |
| 02:41.44 | solar | it's still the nicest of what they offer in the handhelds? |
| 02:41.51 | prpplague | yea |
| 02:42.22 | solar | the cost of it vs other aml products differed a great deal? |
| 02:42.24 | prpplague | solar nicest of what they openly offer, we have a number of other units that are directed to specific customers |
| 02:42.33 | solar | retail/end warehouse. |
| 02:43.34 | solar | like you sent me an older barecode scanner. I'm not sure what model it is. |
| 02:44.09 | solar | but my guess is it could mostly be done with a few avrs. |
| 02:45.08 | solar | but I have a feeling it was not cheap either way knowing a little bit about working with a similar industry in the past |
| 02:46.08 | prpplague | solar hehe, se-950 is pretty expensive |
| 02:47.18 | prpplague | solar an avr can do the decoding, but these days the overall cost associated with doing the algorithums are not worth it |
| 02:47.45 | prpplague | solar the se-950 module thats in the 8050 actually has iMX processor inside |
| 02:48.09 | prpplague | basically an arm9tdmi doing the decoding |
| 02:58.48 | ds2 | ARM TDMI for magstrip stuff?! talk about overkill |
| 02:59.28 | ds2 | I hope this is at least a 3 track reader? |
| 03:01.04 | prpplague | ds2 the arm tdmi is for the barcode scanner |
| 03:01.23 | prpplague | ds2 the magstripe is an asic and 3 track |
| 03:02.15 | ds2 | ah, my bad |
| 03:12.50 | m4t | any of you tried u-boot + qemu + kermit to loadb over a /dev/pts line? |
| 03:14.47 | m4t | i got flow control set to none and baud is 9600 |
| 03:15.03 | m4t | its just retrans after retrans then it quits at 10 errors |

| 16:48.43 | m4t | anyone here done kernel debugging in gdb? |
| 16:53.26 | prpplague | m4t: i have in the past, but i haven't had a need for it in some time, there is a good howto doc on the elinux wiki iirc |
| 16:53.57 | m4t | alright ill look there |
| 16:54.01 | m4t | http://pastebin.com/d1e3ac7c2 is what i got |
| 16:54.19 | m4t | i dunno what else i should do there if you feel like taking a quick look |
| 16:55.00 | m4t | im trying to update the dht-walnut oe target with a bunch of things including u-boot 1.2.0, gcc 4.4.0, new binutils, 2.6.30, etc. |
| 16:55.58 | m4t | that is qemu btw, not a real walnut, but it boots a much older kernel |
| 16:56.11 | m4t | one of the uImages listed at elinux actually |
| 16:57.25 | prpplague | m4t: sorry bud i don't have time to look at it right now, i've got a deadline for some bootloader work |
| 16:58.16 | m4t | oh alright |
| 16:58.33 | m4t | well if anyone else here sees this and feels like taking a look, please do |
| 16:59.13 | m4t | my ac adapter is in the mail so i would like to move this to real hardware soon |

| 19:59.22 | mne | Hi guys. I'm having trouble using the SSC for I2S on an at91sam9260. I multiplexed all pins for use with the SSC in my board file. I also verified that the SSC registers are configured correctly so that the I2S LRC frame sync is being output on the RF0 pin. However, regardless of all my tries during the day I still could not get any frame sync signal on that pin. The frame sync for the transmitter on the TF0 pin is working fine. Since I'm out of ideas I really |
| 19:59.22 | mne | would appreciate any help |
| 20:02.58 | prpplague | mne: you might want to make sure that the frame sync line for the output is not connected to the frame sync line of the input |
| 20:03.24 | mne | it is not connected in any way |
| 20:04.16 | mne | it is directly connected to an audio codec. For testing I also disconnected the line and looked at it with a scope. The behavior is the same |
| 20:08.21 | prpplague | mne: yes i assume it was connected to a codec, the codec will have a frame sync line for the dac , and one for adc |
| 20:08.40 | mne | I also tried it with an external pullup/pulldown resistor but the situation did not change |
| 20:08.49 | mne | right |
| 20:08.59 | prpplague | mne: if both the adc and dac frame sync lines are connected to the same framesync signal that will cause it to not work |
| 20:10.55 | mne | they are not connected. The dac framesync coming out of the atmel ssc pin TF0 is connected to the codecs DACLRC pin. And the receiver framesync coming out of the SSC RF0 pin is connected to the codecs ADCLRC pin. The pins are different pins and not connected to each other. Ir did you mean something different ? |
| 20:11.33 | mne | The SSC as well as the codec are configured for the codec being an I2S slave |
| 20:12.12 | mne | So the SSC is responsible to output the clock and the LRC frame syncs while the only thing the codec outputs is the ADC output ADCDAT |
| 20:20.56 | mne | prpplague, or do you think that the LRC inputs are connected _inside_ the codec ? |
| 20:29.31 | prpplague | mne: no i meant on the pcb |
| 20:29.48 | prpplague | mne: is this a known working hardware platform? i.e. did you build it or buy it? |
| 20:30.34 | mne | I built the audio codec circuitry. The board is a known working platform |
| 20:31.05 | mne | The funny thing is that sound output works since there is a correct LRC frame sync signal for the DAC. |
| 20:32.47 | mne | And if I disconnect the LRC frame sync lines and just measure what comes out of the at91sam9260 evaluation board I also do not see any frame sync signal on the ADC LRC pin. For this reason it must be some kind of software problem (or my evaluation board has a fault) |
| 20:33.39 | mne | If the board has a fault, I could check if there is anything directly on the at91sam9260 RF pin |
| 20:34.09 | chouimat|busy | is tired |
| 20:36.45 | ds2 | Hmmmm |
| 20:36.51 | ds2 | de ja vu |
| 20:49.04 | mne | interesting: On the chip pin the signal looks different. I will solder check if it's an error on the evaluation board |
