That was the basic mistake I think. I was trying to write to a non 32 bit
aligned address. This got solved, but I have some new errors saying this
## Error: environment overflow, "stdin" deleted
## Error: environment overflow, "stdout" deleted
## Error: environment overflow, "stderr" deleted
## Error: environment overflow, "bootcount" deleted
Does that mean the size allocated for env is smaller compared to the actual
contents in env file.
I am new to u-boot. Can you give some pointers on this?
