Please explain what you changed; the config.mk for the  ep8260  board
reads "TEXT_BASE = 0xFFF00000" which looks OK to me.

Type "reset" and "info" and check where the PC is  pointing  to.  You
may  have  a  problem with your BDI's config file so the CPU does not
get stopped immediately after a reset, but  only  after  some  delay.
This  might explain that "reset" and "go" does not work. Also, please
note that  thge  reset  entry  point  is  at  offset  0x100,  so  "go
0xfff00000" is definitely wrong - try "go 0xfff00100" instead.

Another test: disconnect the BDI, and power-cycle the board.

Best regards,

Wolfgang Denk
