Using memtester (in those days 4.0.6) I detected any common problems on
the external RAM parts in the past. It's the very robust memory test:
http://pyropus.ca/software/memtester. You can use this 'as is' or build
a light version (Tip: s@printf@diag_printf@). If it's possible, place
the executable in ROM and use SRAM for .bss .data, etc. i.e. fix the ld
script to prevent a usage the tested RAM region.

Regards,

Sergei
