I don't believe this is the case for most uboot-based boards.... It sure = looks like the mars board I just got has a boot loader, I think uboot, = but I need to finish some soldering to confirm. >> Thankfully, the images for the boot loaders tend to be separable >> from the main image that people load on them and run/boot. >=20 > All of the boards mentioned above require a boot partition > and boot loader chain as part of the main image. Require, or that's one of many ways to update them? 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? > I believe this is common to most of the new hobbyist > boards. That's definitely different than all the other ARM boards I've dealt = with.... Warner
