We use Raw NAND/flash and copy the binary there, After copy, is there a way to check the flash sanity after we have burnt an image? (e.g. by nand reading and diffing with the binary in RAM?)
Are there any feature/utility/commands readily available for u-boot?
I've done it in the past by reading it back to ram and use cmp command. Maybe it is usefull for you, too?
Sure, this can be done. But the NAND driver core supports validation of written data using this configuration option:
CONFIG_MTD_NAND_VERIFY_WRITE
I would enable it only for test purposes though.
