Hi,
Iam using 256MB RAM on arm11 board.I just tried md,mw commands from uboot like the following
mw C800000 0xbbbbbbbb 0x500 here C800000 is the 200MB of RAM
MCS8142>> md C800000 0c800000: bbbbbbbb bbbbbbbb bbbbbbbb bbbbbbbb ................ 0c800010: bbbbbbbb bbbbbbbb bbbbbbbb bbbbbbbb ................ 0c800020: bbbbbbbb bbbbbbbb bbbbbbbb bbbbbbbb ................ 0c800030: bbbbbbbb bbbbbbbb bbbbbbbb bbbbbbbb ................ 0c800040: bbbbbbbb bbbbbbbb bbbbbbbb bbbbbbbb ................ 0c800050: bbbbbbbb bbbbbbbb bbbbbbbb bbbbbbbb ................ 0c800060: bbbbbbbb bbbbbbbb bbbbbbbb bbbbbbbb ................ 0c800070: bbbbbbbb bbbbbbbb bbbbbbbb bbbbbbbb ................ 0c800080: bbbbbbbb bbbbbbbb bbbbbbbb bbbbbbbb ................ 0c800090: bbbbbbbb bbbbbbbb bbbbbbbb bbbbbbbb ................ 0c8000a0: bbbbbbbb bbbbbbbb bbbbbbbb bbbbbbbb ................ 0c8000b0: bbbbbbbb bbbbbbbb bbbbbbbb bbbbbbbb ................ 0c8000c0: bbbbbbbb bbbbbbbb bbbbbbbb bbbbbbbb ................ 0c8000d0: bbbbbbbb bbbbbbbb bbbbbbbb bbbbbbbb ................ 0c8000e0: bbbbbbbb bbbbbbbb bbbbbbbb bbbbbbbb ................ 0c8000f0: bbbbbbbb bbbbbbbb bbbbbbbb bbbbbbbb ................
mw 32000000 0xffffffff 0x500 here 32000000 is the 800MB of RAM
MCS8142>> md 32000000 32000000: ffffffff ffffffff ffffffff ffffffff ................ 32000010: ffffffff ffffffff ffffffff ffffffff ................ 32000020: ffffffff ffffffff ffffffff ffffffff ................ 32000030: ffffffff ffffffff ffffffff ffffffff ................ 32000040: ffffffff ffffffff ffffffff ffffffff ................ 32000050: ffffffff ffffffff ffffffff ffffffff ................ 32000060: ffffffff ffffffff ffffffff ffffffff ................ 32000070: ffffffff ffffffff ffffffff ffffffff ................
How it is possible to see the data even after the 256MB of RAM.If i give the sizes like 256MB ,512MB mw command get hangs otherwise the data is writing to the RAM even the size exceeds the size of actual RAM. Please help me.
Thanks V.Balaji
