Yes. The bootloader doesn't care what you do as long as: * you don't overwrite uboot; * you don't ovewrite uboot-env if it exists; * you put the "uboot application" (ie, the kernel) in the right place (which on these devices is at the beginning of the usable flash area); and * don't ovewrite ART. Just make sure you erase the extra space before you write into it. :) -a On 12 October 2015 at 00:58, Eugene Grosbein <eugen@grosbein.net> wrote: > On 12.10.2015 10:21, Adrian Chadd wrote: >> It's just a hold-over from the atheros layout.
