**** BEGIN LOGGING AT Fri Jun 10 23:59:57 2005 Jun 11 05:15:11 [g2]: ping Jun 11 05:58:59 <[g2]> ep1220, Pong! Jun 11 05:59:17 HI, did you receive my e-mail ? Jun 11 05:59:35 <[g2]> AH... yes... Jun 11 05:59:38 <[g2]> THX Jun 11 05:59:48 <[g2]> I just saw it after you mentioned it Jun 11 05:59:58 i believe you can forward to beewoolie ? Jun 11 06:00:22 <[g2]> absolutely Jun 11 06:00:27 THX. Jun 11 06:00:58 <[g2]> NP, Thank-you ! Jun 11 06:01:25 You can also inlcude my e-mail. Jun 11 06:01:36 <[g2]> ok Jun 11 06:06:05 <[g2]> Looks great! Jun 11 06:06:12 <[g2]> I like the pics too Jun 11 06:06:38 hope they save questions were to connect which wire :-) Jun 11 06:07:30 on the pics there are some LEDS which are not really needed. Jun 11 06:07:50 primarily, to give m fast feedback during development Jun 11 06:12:46 <[g2]> other than review (of which I'm not qualified :( ) what are you planning to do with the design ? Jun 11 06:13:22 no real plan. Jun 11 06:13:42 still want to look into S3/usb Jun 11 06:14:06 well, i could make PCBs. Jun 11 06:14:07 <[g2]> nod.. me too. I think long-term that's the right direction Jun 11 06:14:36 but work and 1xcost would require at leaast 20 takers Jun 11 06:17:20 <[g2]> I still have to figure out why the current digilent isn't working Jun 11 06:17:30 <[g2]> I'll look at that either today or tomorrow Jun 11 06:18:45 maybe there is a bad solderpoint Jun 11 06:19:04 you can compare the wires with my pics. Jun 11 06:19:22 <[g2]> maybe... I think they also attached to the via's Jun 11 06:19:45 I soldered to the Resistor pads. Jun 11 06:20:17 ime vias are hard to solder to (at least with my tools) Jun 11 06:20:28 it can stick but make no contact. Jun 11 06:20:38 <[g2]> well the ppl that did the re-work do that professionally Jun 11 06:21:06 Do You have a voltmeter ? Jun 11 06:21:07 <[g2]> the replaced the memory chips to the 16M16 versioins Jun 11 06:21:11 <[g2]> yes Jun 11 06:21:40 So Yu can check connection header -> SMD resitors Jun 11 06:23:58 Do you have more than 1 modified slug ? Jun 11 06:24:30 <[g2]> right now I've got 1 with 64MB Jun 11 06:24:57 and only 1 with JTAG i asume Jun 11 06:27:14 <[g2]> I've got an OEM board that has JTAG for reflashing Jun 11 06:27:31 and diglent works there ? Jun 11 06:27:59 <[g2]> interestingly no, but I think that's because of the RESET line Jun 11 06:28:42 <[g2]> the digilent cable does work with the S3 fine though Jun 11 06:28:49 <[g2]> and from the same computer Jun 11 06:29:05 <[g2]> using the same tools (jtag) Jun 11 06:29:38 the OEM boots up when nothing is connected to the JTAG header ? Jun 11 06:29:46 <[g2]> yes Jun 11 06:30:08 then leaving RESET and TRST open must not cause problems. Jun 11 06:30:24 Maybe it is Your adapter digilent -> 14pin. Jun 11 06:30:34 <[g2]> that's standard ARM JTAG connector Jun 11 06:30:44 <[g2]> maybe ? Jun 11 06:31:29 if you have 2 boards no work it might be even likely ;-) Jun 11 06:31:56 <[g2]> but that's a different board from the NSLU2 (it has an ixp422, so it is very similar) Jun 11 06:32:12 <[g2]> well it was two different connections Jun 11 06:32:18 <[g2]> there's a header for the nslu2 Jun 11 06:32:39 <[g2]> and I created a patch connector between the digilent and a 14-pin cable Jun 11 06:33:01 maybe this patch connector is the problem ? Jun 11 06:33:24 <[g2]> It *could* very well be that the TDI and TDO for the ARM board are cross with respect to the Digilent cable Jun 11 06:34:07 might be. or the digilent does not firmly connect to Your patch-adapter (?) Jun 11 06:34:41 <[g2]> that seemed pretty good to me but it is possible Jun 11 06:35:00 Also might be the OEM does not have VCC at pins 1 an 13, but these are open. Jun 11 06:35:02 <[g2]> I buzzed the lines with the voltmeters connectivity tester Jun 11 06:35:25 <[g2]> right Jun 11 06:35:35 <[g2]> that's the more likely case Jun 11 06:36:07 you can check with voltmeter. Jun 11 06:36:17 <[g2]> nod. Jun 11 06:36:46 a "real" JTAG should have VCC, many (professional) adapters need power from the target Jun 11 06:37:03 or at least measure it to set the level-shifters Jun 11 06:39:25 <[g2]> I was very close on my last JTAG soldering attempt on the NSLU@ Jun 11 06:39:44 <[g2]> then pulled off a pad Jun 11 06:40:39 oops Jun 11 06:41:19 <[g2]> risks for the advancement of science ! Jun 11 06:42:54 You deserve a medal for "researching wihout any sign of fear" :-) Jun 11 06:43:40 <[g2]> hardly Jun 11 06:44:24 <[g2]> when at my last startup I had a $25K development system for a network processor Jun 11 06:44:51 <[g2]> so risking $80 on a device pales in comparison Jun 11 06:45:19 <[g2]> it was another $20K for the sw on the development system Jun 11 06:46:11 and ... did You kill it ? Jun 11 06:46:26 <[g2]> no. Jun 11 06:46:43 <[g2]> but we did put wires on many $20K boards Jun 11 06:48:01 <[g2]> It much more fun working on the little stuff Jun 11 06:48:06 <[g2]> it's all basically the same Jun 11 06:48:28 yes Jun 11 06:50:09 I just look at the FTDI Linux driver. Jun 11 06:50:32 Kernel 2.6 not tested. only tested with mandrake. Jun 11 06:50:46 If it does not work, remove the serial driver , .. Jun 11 06:50:49 :-( Jun 11 06:51:05 seems low in their priorities Jun 11 06:51:09 <[g2]> Linux drivers we can fix Jun 11 06:51:16 but they give no source Jun 11 06:51:37 <[g2]> for FTDI, I think we can turn a host into a USB 1.1 analyzer Jun 11 06:52:33 we can log USB commands. Jun 11 06:52:41 <[g2]> nod. Jun 11 06:52:46 but this is not funny. Jun 11 06:53:11 <[g2]> what's that ? Jun 11 06:53:44 this is no fun (is better english ?) Jun 11 06:53:51 <[g2]> Ah... Jun 11 06:53:53 <[g2]> yes Jun 11 06:54:10 <[g2]> "but this is not fun" Jun 11 06:54:23 learned something Jun 11 06:56:06 <[g2]> the two real important things about this are Jun 11 06:56:25 <[g2]> 1) You've figured out how things work Jun 11 06:56:33 <[g2]> 2) You've actually verified it Jun 11 06:56:50 <[g2]> so now there's another working model Jun 11 06:58:07 I use an FTDI driver. Do not send data directly to USB bus Jun 11 07:04:01 <[g2]> ep1220, if you sent stuff directly to the USB bus there would be no need for monitoring :) Jun 11 07:04:21 agree Jun 11 07:09:43 I want to start doing FPGA stuff and install the Xilinx WebPack, but the qemu linux emulation is incredibly slow on my 800 MHz powerbook :) Jun 11 07:12:22 <[g2]> I'll see you guys later Jun 11 07:12:27 <[g2]> cheers Jun 11 09:18:27 there you are... Jun 11 09:19:55 it's tooo early. even though it's saturday... Jun 11 09:20:21 especially since its Saturday. Jun 11 09:20:25 point **** ENDING LOGGING AT Sat Jun 11 23:59:56 2005
