WE NEED TO RUN THE WHOLE THING FROM SD!
No need to shout.
u-boot loads the uImage (linux-2.6.27)from SD to 0x22000000 u-boot does Bootm 0x22000000 (0x22200000 shows same result)
Linux starts , but fails! see screen copy: Uncompressing Linux.................................................................................................... crc error
What went wrong? Can you help?
Obviously there is some memory corruption.
An Alternative is an uncompressed Kernel in order to come around the crc issue. Then Linux kernel starts, but crashes after 100lines of messages anyway.
Could be some memory corruption.
We found comments in some forum that flushing/invalidating the icashe/dcashe is required when SD is used before u-boot is going on to run the kernel.
Indeed it is a good idea to make sure caches are properly flushed.
Best regards,
Wolfgang Denk
