Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1.When i am running "mw" command from the u-boot, the board is hanging up
2.I want to test complete 128MB of SDRAM by writing some data into that
3.so what i am doing is

"mw.l 0x80000000   0x18FFFFC"
 but its writing up to 0x80e613c0. 

What is the expected output? What do you see instead?

when i see the memory by the command "md 0x80000000"
memory should be filled with 0xdeadbeef up to 0x18FFFFC

but its hanging up at 0x80e613c0.
Even for writing 14MB memory it is almost taking 3 hrs
I am not able find where is the problem

What version of the product are you using? On what operating system?
B6 , Fedora 7

Please provide any additional information below.

I can be able to test this SDRAM in X-Loader 1.41 and its writing within
the second
