Hi folks
has anyone tried making Redboot ROMRAM start?
I want to get around the limitation that you cannot use Redboot and
flash programming in the application. If you do, while the
program/erase operation happens, the application can decide to jump
into redboot, which is also in flash, and it all goes horibly wrong.
Im doing this on the EBSA, and at the moment it dies when redboot
starts. According to the LED sets in Vectors.S its go to
cyg_user_start, but there is no activity on the serial port.
Any ideas or past experiance?
Andrew
