[microblaze-uclinux] netflash, checksum, and u-boot

[Jim Van Vorst <jvanvorst@xxxxxxxxx>]

Hi all,

I'm looking at netflash to upgrade my kernel and I wanted to add the 
hmacmd5 hash to the image, but there seems to be an order of operations 
problem.  The vendor common.mak file appends version info to image.bin, 
then runs the hmacmd5 tool, THEN prepends the u-boot header to create 
image.ub.  Now u-boot wants to load image.ub from flash (i.e. needs the 
64 byte u-boot header) but when I run netflash on the image.ub image the 
signature check fails since the u-boot header was added AFTER the 
signature.  I can netflash image.bin but u-boot doesn't like it.

Should the makefile be changed to sign the image.ub file, or should 
netflash skip the u-boot header before the signature or what?


Thanks,
Jim
