Re: [ECOS] How to execute the program in eCos for ARM

[Cristiano Ligieri Pereira <cpereira at ics dot uci dot edu>]

I hit the send by mistake in the previous one... :-)

Is it necessary to change the definitions of SA11X0_ROM_BANK0_BASE and
SA11X0_RAM_BANK0_BASE in the file
packages/hal/arm/sa11x0/var/current/include/hal_sa11x0.h to match the
memory mapping of the board?

Thanks,
Cristiano.
