**** BEGIN LOGGING AT Wed Jul 14 02:59:56 2010 Jul 14 19:30:04 I'm trying to communicate with an arm cortex m3 processor on a custom pcb. I have one board put together that works flawlessly, both jtag and in every other way. I have a second board that has the error "Error: 115 589 core.c:938 jtag_examine_chain_check(): JTAG scan chain interrogation failed: all ones" and "Error: 116 590 core.c:939 jtag_examine_chain_check(): Check JTAG interface, timings, target power, etc.". Any ideas? could the proc Jul 14 19:30:04 essor on the second board be broken? Jul 14 20:08:44 might be almost anything Jul 14 20:08:59 bad soldering/solder bridge/ESD etc Jul 14 20:09:50 maybe check if you can get into the serial bootloader Jul 14 21:33:28 allones generally means 'nothing happened' e.g. no power, stuck in reset, wries not connected. **** ENDING LOGGING AT Thu Jul 15 02:59:56 2010
