This time, I loaded the uImage to 100000 and pRamdis
to 200000. The boot code transfers control to Linux as
following:

The crc error is still there as:
RAMDISK: Compressed image found at block 0
crc error<6>Freeing initrd memory: 1367k freed
VFS: Mounted root (ext2 filesystem).
Freeing unused kernel memory: 56k init

Then, system stuck.

Someoen can help on this?? please!!

Thanks, I made a mistake, it should be root=/dev/ram0
rw, not boot=/...
 
Sorry I response too late. I have another project on
hand, so I can only work on this one couple hours a
day.
