Hi Robert, I understand what you are attempting to do, but won¹t it be more helpful if you explained to your students how to interpret the console output. For example if there is no MLO, you will see ³CCCCCC² printed. If it cannot find a valid u-boot or DTB file. What happens when there is no kernel magic number. What happens when there is no valid rootfs, etc. Just a thought. Regards, John > >rday > >-- > >======================================================================== >Robert P. J.
