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 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??
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)

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.
i have checked the SDRAM configuration settings everything is fine as per the device datasheet.
please i want to know where is the problem, what is the cause for this exception. why memory test fails after 40-60mins.
error output is as attached:-

If this is one chip, are there really 256,5 MB ?

I cannot see here in this log, where you typed mtest ...
please see the attachment in this mail.i have captured the log file from hyper terminal.
Hmm.. I looked in the log. Is this right, that if you get this error u-boot never returns to the shell prompt?
Also from your log: Pattern 0000158A Writing... Reading... Mem error @ 0x0071E65C: found 00008F3F, expected 00008F21 ^^ ^^
Pattern FFFFEA75 Writing... Reading... Mem error @ 0x00723684: found FFFF5CB6, expected FFFF5CD4 ^^ ^^ always the last byte seems broken
Is there getting something hot and the board, and maybe disturb this datalines?

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

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
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

Hmm... nothing spring to my mind, just the "standard" things:
check your - HRCW - clocks - SDRAM settings

The MPC8260 has different configuration options to compensate (I presume) for hardware clocking delays, etc. when it is run fast vs. slow. If you have your CPU misconfigured for running at a slow speed but actually clocking fast, I would expect your CPU and bus will be flaky.
IIRC (it's been a while), you need to read the reset section of the User's Manual and make sure your Hardware Reset Configuration Word and configuration strapping pins are correct for the clocking you are using.
