Subject: Relocating PPCBoot into SRAM
Date: Sun, 16 Feb 2003 12:54:35 -0500 [thread overview]
Message-ID: <200302161254.35753.ADharankar@ATTBI.Com> (raw)
Greetings!
- On MPC75x and MPC7410 boards with MPC8260 in companion
mode, SRAM on 1M and 2M respectively are available.
- Is it possible to relocate PPCBoot to this SRAM mapped
as private memory? 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.
