Configure Wifi

symlink wlan0

root #cd /etc/init.d/
root #ln -s net.lo net.wlan0
root #rc-config add net.wlan0 default

create /etc/conf.d/net file

FILE /etc/conf.d/net
# Set the dns_domain_lo variable to the selected domain name
dns_domain_lo="homenetwork"
modules_wlan0="wpa_supplicant"
wpa_supplicant_wlan0="-Dnl80211"
config_wlan0="dhcp"

Features

Cross compile preparation

Setup:

root #emerge --ask crossdev
root #crossdev i686-pc-linux-gnu

Copy package to Intel Edison:

root #scp -r /usr/i686-pc-linux-gnu/packages root@192.168.0.102:/usr/portage/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 /usr/portage/

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

let's add a new kernel in the /mnt/boot folder 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
