RE: [ECOS] EB40a: loading hello world

[Ketil Harald Ruud <ketil dot ruud at kitron dot com>]

For the interest of others having the same problem:
The reason for the problem is that redbootRAM is not setting up EBI to
handle the external RAM. When I tried to access the external RAM from
redbootRAM, a bus error occured resulting in the error message described.

2 solutions to the problem:

1) Let redbootROM load redbootRAM, and then start redbootRAM. EBI will now
be setup (by redbootROM) to handle the external RAM. The application can
then be loaded to external RAM by redbootRAM.

2)Change /hal/arm/at91/eb40a/current/include/hal_platform_setup.h to setup
the EBI to handle external RAM for redbootRAM also.

Thanks to Laurent Gonzalez for helping me with this problem.
