Hi,
I’m still struggling to drill down to the root cause, but this is what I have found so far:
If I reset the target and then resume it with OpenOCd rev 247, everything works OK. For rev 272 and 276, OpenOCD exits without any warning. The lines that causes the exit(-1) are:
File: arm7_9_common.c
Function: arm7_9_restart_core(…)
Line 1391:
if ((jtag_execute_queue()) != ERROR_OK)
1392 {
- 1393 exit(-1);
1394 }
Does anyone have any insight?
Thanks!
Pieter
