I'm working on a custom board design based somewhat on the mx6qsabresd board. This board has a 512Mb Micron SPI NOR flash chip on it that we'd like to put everything on including a core-image-minimal rootfs that was built using Yocto Morty. Ideally, the boot process would extract a compressed version of the rootfs into a ramdisk and run from there. We plan to use MFGtool to flash the boot image. Can someone point me to any resources for doing this that might be helpful?
