Note that, this is a second relocation; the first would already have occured when it is relocated from Flash to SDRAM. - And if this possible, a re-relocation from SRAM back to SDRAM? If this is possible, what needs to be done? The idea I would like to explore is to do a full memory test (walking bit, aligned/non-aligned access, refresh, alternating pattern, random pattern test - basically extensive testing) without executing PPCBoot in SDRAM. And that these tests are part of PPCBoot commands (or applications, perhaps). Best regards, -Arun. ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
