| 19:14.19 | AchiestDragon | ok http://www.openjtag.net is back online ,, so far managed to reformat the main page ,, is there any additions needed to that page atm or is that fine ? |
| 19:16.09 | AchiestDragon | and its a fresh install of the wiki software so any old account info was lost |
| 19:17.27 | AchiestDragon | sofar i have only managed to reformat the main page ,, theres no other pages done as yet |
| 21:07.00 | ka6sox-office | kewl...thanks |
| 21:07.16 | ka6sox-office | I"m kind of swamped today so anything that you can do would be a great help. |
| 21:07.58 | AchiestDragon | well its not as easy as it looks , those original files each contain all the old edits also |
| 21:08.45 | AchiestDragon | and its hard trying to figure out whats current and what whas changed |
| 21:09.25 | AchiestDragon | http://www.openjtag.net/index.php?title=Hardware_design_discusion&oldid=21 for example |
| 21:10.19 | AchiestDragon | its actualy easyer to rewrite the site from scratch , thats what im doing atm |
| 21:10.43 | AchiestDragon | recovering old content where i can from the old wiki files |
| 21:11.51 | AchiestDragon | im also wanting feedback on the current state of the project so i can update it at the same time |
| 21:12.21 | AchiestDragon | like how well did the ft2232c design perform |
| 21:13.07 | vmaster | FT2232 based devices are offered by a variety of commercial parties, including FIC/OpenMoko for their Neo1973 |
| 21:13.38 | vmaster | the only software I know that supports it is the OpenOCD and a proprietary driver from LuminaryMicro for their Cortex-M3 devices |
| 21:13.43 | AchiestDragon | not only that but that guy who emailed me seems to be close to getting his ft2232 based board with a cpld for jtag use close to compleation |
| 21:13.47 | vmaster | ah, and Rowley, either now or in future |
| 21:14.08 | AchiestDragon | ok so nothing happening mutch on that ,, |
| 21:14.38 | AchiestDragon | what if anything is dead that dosent need to go back on ,, i know the aztag is |
| 21:15.28 | AchiestDragon | but we now have the geep-b getting colse to being prototyped when we get the pcb's that is ,, |
| 21:16.42 | AchiestDragon | i have left room for a parallel port version and a usbdongle based one , as i feel that its still going to be of some use to some |
| 21:18.00 | AchiestDragon | i would like to add a project status/news section to the main page but i am not shure what the current state is |
| 21:26.47 | *** join/#openjtag bullet (n=bullet@196.210.62.81.cust.bluewin.ch) |
| 21:33.14 | vmaster | AchiestDragon: 22:15 < AchiestDragon> not only that but that guy who emailed me seems to be close to getting his ft2232 based board with a cpld for jtag use close to compleation |
| 21:33.25 | vmaster | never heard about that - can you tell me more? |
| 21:35.09 | AchiestDragon | he emailed me asking why the openjtag site was offline |
| 21:35.29 | vmaster | ah, i only noticed it was offline when you asked why |
| 21:35.43 | AchiestDragon | he said |
| 21:35.47 | AchiestDragon | >>>> Does OpenJTAG has a real open JTAG hardware now? |
| 21:35.49 | AchiestDragon | >>>> In the moment I am working on a USB-JTAG hardware |
| 21:35.51 | AchiestDragon | >>>> with a ARM cpu and a CPLD. It should work up to 24MHz |
| 21:35.53 | AchiestDragon | >>>> JTAG clock. |
| 21:35.57 | vmaster | ah, that's michael fischer |
| 21:36.07 | AchiestDragon | in his email |
| 21:36.11 | AchiestDragon | ah you knonw him |
| 21:36.13 | vmaster | just saw you mentioned yagarto |
| 21:36.30 | vmaster | yeah, he's creating the windows binaries for the OpenOCD, and maintains some howto pages |
| 21:36.47 | AchiestDragon | anyway he has a problem with the cpld on his design atm |
| 21:37.00 | AchiestDragon | its written in verilog though |
| 21:37.12 | vmaster | uhm, the last simulations he sent me seemed to be fine |
| 21:37.48 | AchiestDragon | well i dont trust simulators , there not as effective at spotting some problems as they should be |
| 21:39.15 | AchiestDragon | especialy some timing related problems |
| 21:40.25 | vmaster | yeah, of course, but originally there was a misunderstanding on how his cpld should operate, which i believe he got solved by now |
| 21:41.04 | AchiestDragon | anyway i doubt that it will achive 25mhz |
| 21:41.48 | AchiestDragon | the usb speed is going to limit it |
| 21:43.23 | AchiestDragon | unless he has some ram buffer on there also |
| 21:47.08 | AchiestDragon | i may be wrong |
| 21:47.10 | vmaster | the lpc2148 has 32kb |
| 21:47.45 | vmaster | and it's certainly not going to reach 24mhz, unless you offload a lot of "logic" to the LPC |
| 21:49.22 | vmaster | but i suppose several mhz are possible, and a sustained frequency of 6-10mhz would be a 4x increase over the ft2232 |
| 21:49.36 | AchiestDragon | yes |
| 21:50.28 | vmaster | the ft2232 has a maximum frequency of 6mhz, but i have no idea how you could possibly reach that - buffers are too small and usb latency is to big |
| 21:54.39 | AchiestDragon | i remeber formating a 10G usb hdd and it taking a hour or so |
| 21:57.29 | AchiestDragon | only ever did it that way once , now i remove its ide to usb adaptor and stick it in a machine to do that |
