The usual way in = all the boards I've dealt with is that one generally doesn't update the = boot partition, but you do update the kernel and root partitions = (possibly with repartitioning). Are you sure that you are required to = include the primary boot loader when updating? >=20 > The RPi, BeagleBone, and PandaBoard do not have onboard flash. >=20 > They all boot from SD card and require that the SD card > have an MSDOS FAT partition containing the boot loader. Ah, the light goes on... Most of the cards I've dealt with have actual = flash, but can boot in this mode in a recovery mode... Warner=
