i am using MPC8280 in our board which has 512MB of SDRAM i.e. from micron.
Is this board in mainline, so I can look in the Source Code?
yes this board is in mainline.only one board.
And which board is it? means ? it is MPC8280 based board called remote I/O board
How do you compile it?
make xxx_config
What is xxx for you? I looked in code but couldn;t find a "SLN Technologies" string ...
As I saw in your log, it uses the "normal" mtest. Try to use
CONFIG_SYS_ALT_MEMTEST
how to use this...where to add...command for this test??
You just have to add this define in your board config file. I looked in 1.3.1, so you should add a
#define CFG_ALT_MEMTEST 1
i have added this line. after adding this which command i have to give..same mtest or any other command for CFG_ALT_MEMTEST ??
instead. (Hopefully, this is available in 1.3.1 ...)
Which u-boot version?
U-boot version is 1.3.1.
Hmm.. this is very old ...
which is the latest version of u-boot ,can i upgrade the current version of u-boot to latest version i.e. from u-boot 1.3.1 to latest u-boot without reinstalling ELDK

Which SDRAMs?
SDRAM is MT48LC32M16A2 from Micron.
when i give command mtest only for 1MB to check memory test from U-boot, machine check and program exception is coming after 40 - 60mins later it hangs giving program check exception
Hmm... maybe problems with your SDRAMs?
if it is SDRAM problem it should not work for 1hour also i think.
Why not?
ok
Is this error shown always after 40-60 mins, not sometimes also earlier?
maximum i am able to run mtest for 1hr 30 mins. sometimes it hangs with 45mins also.
Not earlier?
sometimes earlier but rare
Hmm...
Can you boot a Linux Kernel for example?
No. our job is to only give the board with U-boot boot loader, Linux booting is done by our client.
But you can try it ... This would help here, to stress more the SDRAMs ... also you can do better memtests there/with it.
i got one new error which is below :- U-Boot 1.3.1 (Jul 27 2009 - 17:27:10)
[...]
DRAM: 512 MB
it hangs here only if i press manual hardware reset many times also.
if i power off & switch on then it reboots in normal way again.
Hmm... nothing spring to my mind, just the "standard" things:
check your
- HRCW
- clocks
- SDRAM
settings
