Thanks to Dirk for your previous advice. We had a pullup on one of the reserved BOOT_CFG pins that caused problems accessing NOR flash.
Now I can put code in the NOR flash. If the code is incorrect in some way (not sure how yet), I end up with a board that I can't get control of with the BDI. I get
- TARGET: processing reset request - TARGET: BDI executes scan chain init string - TARGET: Bypass check 0x00000001 => 0x00000004 - TARGET: JTAG exists check passed - Core#0: ID code is 0x4BA00477 - Core#0: DP-CSW is 0xF0000000 - Core#0: DBG-AP at 0x82150000 - Core#0: DIDR is 0x3513702A - TARGET: Reset sequence passed - TARGET: resetting target passed - TARGET: processing target startup .... # TARGET: core #0 startup failed # TARGET: timeout while waiting for debug mode # TARGET: processing target startup failed # TARGET: timeout while waiting for debug mode I've tried different STARTUP modes, adding WAKEUP delays, different RESET modes all of which don't help.
Any suggestions?
Thanks, Carolyn
