Re: [U-Boot] [PATCH 3/5 v1] integrator: do not test first part of the memory

Hi Linus,

Le 18/09/2011 09:52, Linus Walleij a écrit :

When booting from Flash, the Integrator remaps its flash memory from 0x24000000 to 0x00000000, and starts executing it at 0x00000000. This ROM thus hides the RAM underneath and first 0x40000 bytes of the memory cannot be tested by get_ram_size(). So let's test from 0x40000 to the end of detected memory instead.

Is this masking of RAM by FLASH a hardware thing that cannot be avoided? Can't the U-Boot startup code somehow remap the FLASH elsewhere, and then proceed to really test the whole RAM?

Amicalement,
