| 17:57.45 | purl | beewoolie-afk <n=beewooli@206.124.142.26> was last seen on IRC in channel #openjtag, 3d 22h 53m 3s ago, saying: 'just returned from skiing.'. |
| 18:04.55 | NAiL | hmm |
| 18:05.04 | NAiL | how sensitive to length are JTAG cables? |
| 18:05.49 | lennert | depends on the speed you're driving them at, i'd guess |
| 18:06.30 | NAiL | hmm |
| 18:06.32 | vmaster | 20cm worked for me nicely at a few mhz, at 40cm there was no reliable communication above 1-2mhz |
| 18:07.00 | NAiL | I don't know how fast I need it... |
| 18:07.16 | vmaster | a wiggler does ~350kHz |
| 18:08.06 | NAiL | hmm |
| 18:08.29 | NAiL | My cable is 18cm, but I need to tack on some form of converter for the ds101 |
| 18:10.00 | NAiL | but I don't need to run at high speeds, do I? I basically just need to upload a kernel :) |
| 18:12.02 | lennert | the speed you need to run at depends on how long you are willing to wait ;) |
| 18:12.11 | NAiL | ah, good |
| 18:12.37 | NAiL | how long would I expect to wait when using e.g. a wiggler? |
| 18:12.44 | NAiL | for a 1mb kernel uploaded to ram |
| 18:13.53 | NAiL | ie, is it minutes, hours, days? ;) |
| 18:13.59 | koen | weeks? |
| 18:14.01 | lennert | minutes, i guess |
| 18:14.18 | lennert | just a few minutes |
| 18:14.29 | NAiL | doesn't sound too bad. I could stand to wait an hour or two once in a while, but days would be painful ;) |
| 18:15.43 | NAiL | (used to uploading the darn kernel with xmodem to the ds101 anyways) |
| 18:26.57 | lennert | case $TARGET in |
| 18:27.02 | lennert | <PROTECTED> |
| 18:27.08 | lennert | whoops, wrong channel :) |
| 18:27.16 | lennert | (that's from crosstool) |
| 19:02.24 | prpplague | NAiL: i've seen my wiggler stuff behave quite odd with long cables that were not properly grounded |
| 19:02.43 | prpplague | NAiL: thats the main reason that the change was made from the 2x7 header to 2x10 |
| 19:02.48 | prpplague | NAiL: for arm that is |
| 19:02.57 | NAiL | yeah |
| 19:02.57 | prpplague | NAiL: so that every other wire was ground |
| 19:03.36 | NAiL | the plug I'm going to use will actually have every other wire as GND (by accident rather than design ;) |
| 19:04.13 | prpplague | NAiL: generally what most ppl will do is upload a micro-bootloader that initializes some interface like a uart to do the actual upload of soemthing like the kernel |
| 19:04.38 | NAiL | like APEX |
| 19:04.48 | prpplague | or even smaller |
| 19:04.54 | prpplague | i have one that is just 1k |
| 19:04.59 | NAiL | ooh |
| 19:05.10 | NAiL | but will it work on my board? |
| 19:05.11 | prpplague | all it does is init the uart, and prepare for a xmodem transfer |
| 19:05.24 | prpplague | NAiL: what is your board? |
| 19:05.34 | NAiL | it's an intel ixp420 |
| 19:06.30 | ka6sox | DS? |
| 19:06.33 | NAiL | yeah |
| 19:07.15 | NAiL | I just need to be able to transfer the kernel and boot it |
| 19:07.26 | NAiL | so I can re-write the b0rked redboot |
| 19:09.23 | NAiL | bbiaw, watching corpse bride |
| 19:09.28 | prpplague | i don't see any reason you couldn't make an app for the ixp420 |
| 19:17.25 | AwayNAiL | well, I'm not much of a programmer ;) |
| 19:17.37 | AwayNAiL | if uploading apex would work, I'm satisfied |
| 19:17.59 | prpplague | AwayNAiL: ahh |
| 19:21.29 | AwayNAiL | This JTAG-stuff is first and foremost for a one-time recovery of my DS101. |
| 19:22.38 | lennert | one-time.. that much confidence in yourself? :-) |
| 19:25.10 | vmaster | hehehe |
| 19:26.25 | prpplague | DS101 ? |
| 19:26.31 | lennert | i always make the same crucial mistakes at least twice |
| 19:29.01 | AwayNAiL | hehe |
| 19:29.17 | AwayNAiL | prpplague: Synology DS101. http://www.nslu2-linux.org/DS101/ |
| 19:30.08 | prpplague | ahh a slug device |
| 19:31.13 | AwayNAiL | basically, yes |
| 19:31.23 | AwayNAiL | twice the ram, twice the flash, and internal IDE |
| 19:31.35 | AwayNAiL | unfortunately, the flash is DiskOnChip |
| 19:32.28 | prpplague | AwayNAiL: ug |
| 19:32.37 | prpplague | AwayNAiL: i'd get rid of that |
| 19:35.43 | AwayNAiL | well, not very easy that |
| 19:36.42 | AwayNAiL | (and, it makes making a custom firmware useable by others a real pita ;) |
| 19:39.14 | prpplague | AwayNAiL: doc is pretty easy to replace |
| 19:39.28 | prpplague | AwayNAiL: since you have all the data and address lines available |
| 19:48.50 | AwayNAiL | yeah, but I'd need a flash chip to replace it with |
| 19:50.41 | AwayNAiL | and a steady enough hand to solder it ;) |
| 19:56.30 | ka6sox | AwayNAiL, I have replaced the flash before...its a NIGHTMARE |
| 20:01.55 | AwayNAiL | I don't doubt it ;) |

| 20:34.13 | NAiL | Anyway, as long as I can boot linux once, I should be able to recover fully |
| 20:38.26 | prpplague | NAiL: there are plenty of small 4 port hubs |
| 20:38.38 | NAiL | yeah, I've got one that I consider ripping apart |
| 20:38.48 | NAiL | the casing is huge, but the PCB itself is small |
