JC 02:37 PM Software Development: RE: Reading contents of a file in Uboot

u-boot doesn't really have a lot of file io ability.
You can load a file from sd card, tftp, nfs, or nand into memory. But the only way I know to look at it would be with "md" though that will just print the hex values in memory.
