Beagle Board Rev C3 Booting Issue

I am using Beagle Board rev c3, i had flashed the NAND using RevC4 image. When I tried to run memory test by issuing the command mtest 0x80000000 0x81000000 0xDEADBEEF 1 to u-boot, nothing happened and board got hanged, so I resetted the board by pressing reset button.
After that when I tried to boot the kernel then following error occoured…
Uncompressing Linux Kernel…
crc error
–system halted
Can anyone tell what has happened? I think RAM has got damaged!!!

RAM got damaged by a wrong SW command? If it was possible guys supporting these boards cut their veins trying to recover all broken stuff :slight_smile:

So, Should I send the board using RMA on ??
