I have a problem with redboot on Atmel EB55 eval board.
I built redboot (RAM version) from cvs ecos tree.
I loaded it into the board via OCD Commander + wiggler.
Before giving download command I ran the following script for settting up
EBI controller:
endian little
speed 2
word 0xffe00000 = 0x01002529 ;CSR0
word 0xffe00004 = 0x02002121 ;CSR1
word 0xffe00020 = 0x00000001 ;remap
word 0xffe00024 = 0x00000000 ;standard read
CPSR = 0xd3
I connected a terminal on the serial port 0 and I saw the redboot initial
message.
After a while (few seconds) the board was executing the "led swing example"
in the FLASH. For some reason the board reset.
I supposed this was because of watchdog intervention so I created a modified
version of redboot (with watchdog disabled) but the problem remained. I also
tried with the pre-built redboot elf file on the cvs but the result was the
same.
Any ideas?
Thanks,
Lorenzo Midulla
