I had a similar problem working on redboot on an ARM based board.
Better option is to use ROM mode.
What is the board specified start address? If that is correct, I think u
don't need to use go. u just restart the system & the processor will
load and execute the code of redboot on its own.

If u got it working in any other mode, do share it with me.

[ECOS] Porting RedBoot to ARM9 based OMAP5912 - Doubt.

[Pradeep Padmanabhan]

Hi all,

I am a newbee to eCos Porting. As a part of my learning I am trying to
port RedBoot to a ARM9 based OMAP5912 platform. The platform already
has U-Boot running on it and I want to port RedBoot alongside in RAM
startup mode.

Using the configuration tool (ver 2.0 in Linux) and hand editing the
.h and .ldi files I was able to build a .bin image. When I tried to
load this image and execute it on the omap 5912 OSK, the RedBoot
prompt does not appear. The system just stays there without any
messages.

I am loading the .bin image at the address 0x10000000 which I have
mapped as RAM origin and execute it using the 'go' command.

Any suggestions on what lines to proceed would be great.

Thanks,
