Re: Memory test for etrax




Hi,

I also had this task.  As Mikael noted you can do sdram test through
--memtest option.  For the flash test I calculate checksum of the flash to
match the checksum of fimage through custom --flashtest option.  And if
linux boots up succesfully I suppose the rest of the hardware is okay ;-)
