Features
Cross compile preparation
Setup:
root #emerge --ask crossdevroot #crossdev i686-pc-linux-gnuCopy package to Intel Edison:
root #scp -r /usr/i686-pc-linux-gnu/packages root@192.168.0.102:/var/cache/packages/Install in Intel Edison:
root #emerge --ask --oneshot --usepkgonly <package atom> Squashfs Gentoo repository
Mount squashfs or use sd-card:
root #mount /portage.squash /var/db/repos/gentoo/
Kernel multi-boot
Increase the Edison boot partition:
root #mount /dev/mmcblk0p7 /mnt/boot/
root #mkdir /tmp/boot
root #mv /mnt/boot/* /tmp/boot
root #umount /mnt/boot
root #mkfs.vfat /dev/mmcblk0p7
root #mount /mnt/boot
root #cp /tmp/boot/* /boot
Add a new kernel in the /mnt/boot directory. For example vmlinuz_01 and vmlinuz_02:
multi boot with u-boot for start vmlinuz_01
boot > setenv load_kernel fatload mmc 0:7 ${loadaddr} vmlinuz_01
boot > boot
