[U-Boot-Users] crc check on the u-boot image(bin-file)
Hello all u-boot users I have a question about if anyone know if there is any way to generate an CRC check on the u-boot image itself. So you can check that your flash image is intact before you start uClinux. uClinux itself is in a header that is CRC supported.
Thanks in advance.
Best regards Anders Öhlander

Of course there is such a way. You just have to implement it :-)
But this obviously depends on your system coniguration - for example, if your environment is "embedded", you cannot simply checksum the U-Boot image in flash since a simple "saveenv" will change it. SO your code will be pretty configuration dependent, and it will take a bit of thinking to implement this right.
