Mar 29 10:11:08 wont work on embest board, and wont work on my board :-( Mar 29 10:11:19 heh, can you define "wont work"? Mar 29 10:11:48 Error: jtag.c:1123 jtag_validate_chain(): Error validating JTAG scan chain, IR Mar 29 10:11:48 mismatch, scan returned 00 Mar 29 10:12:48 and this error with the latest version Mar 29 10:13:07 Error: jtag.c:1181 jtag_examine_chain(): JTAG communication failure, check con Mar 29 10:13:07 nection, JTAG interface, target power etc. Mar 29 10:14:24 aahh, now it works on embest demo board, but wont work on mine Mar 29 10:16:37 ok, so at least the JTAGkey aint broken Mar 29 10:17:05 can you paste a complete log using the latest version on your own board (pastebin.ca)? Mar 29 10:17:23 sure Mar 29 10:18:09 The AT91RM9200 implements two TAP controllers - one for boundary scan, the other for debugging. Is JTAGSEL (don't remember the exact name) pulled to the correct level? Mar 29 10:18:32 I check right now, but i think so, yes Mar 29 10:19:28 you can also try decreasing the TCK frequency (higher jtag_speed value) Mar 29 10:20:56 JTAGSEL is low, also ICE Mode Mar 29 10:21:04 not Boundary Scan Mar 29 10:21:58 http://pastebin.ca/414835 Mar 29 10:23:56 hmm, the JTAG interface is completely unresponsive Mar 29 10:24:06 try increasing jtag_speed to a value of 10 or 20 Mar 29 10:24:25 have you got your xtal's working? Mar 29 10:24:50 ok, yes Mar 29 10:25:00 but it is a real noob failure :-( Mar 29 10:25:12 heh, what was the problem? Mar 29 10:25:26 checked everything against my curcuit sheets Mar 29 10:25:31 not against the data sheets Mar 29 10:25:55 and i made a terrible failure with the power supply of VDDPLLA, VDDPLLB, VDDOSC Mar 29 10:26:10 I applied 3,3V to any of these pins, and they need 1,8V Mar 29 10:29:12 I'm out for lunch, will be back in 15mins Mar 29 10:43:37 yeah, just had lunch, too Mar 29 10:44:46 I'm back again :-) Mar 29 11:10:16 drath: Found my problem Mar 29 11:10:40 TDO <-> TCK twisted on my adapter card Mar 29 11:19:47 aproemel: ah, ok, so it's working now?
