I have lots of instability issue with one of broadcom-mips based board. After some testing i would say it is partially jtag adapter issue. Incorrect pull-ups/downs and, wrong cable and so on will couse different noise issues. For example i have adapter which works perfectly on Atheros based mips at 100kHz. And same adapter regularly fail on Broadcom-mips even with lover speed: 10kHz. > > Did you see this before you lowered scan_delay?
