[ECOS] ARM AEB-1 download problem

[ECOS] ARM AEB-1 download problem

[Koeller, T.]

I am trying to install the GDB stubs from eCos 1.3.1 on my ARM AEB-1 board.
The method described in the tutorial does not work for me, because I do not
get a prompt from the ROM boot monitor. The first prompt I see is from
Angel.
So I tried the method described for the PID, but that did not work either
(see
transcript below). Anyone able to help me with this?

Did you try pressing ENTER just in case?

Sure this is an AEB-1?!

Firstly: This image will have a load address (LMA) that points into flash,
which is why it thinks it is wrong. You' would need to tweak it using
arm-elf-objcopy to load it into RAM.

But secondly it doesn't matter because there's no mechanism to program it
into flash - there's no flash driver, which is why you need the AEB boot
monitor.

Unless this really is an AT91EB0x, in which case there's an eCos port in
anoncvs.
