I've noticed a few issues with the pandaboard image that builds.
1. core-image-sato does not have WiFi capability. I think it's missing firmware.
2. core-image-base is missing the linux-firmware. I added:
IMAGE_INSTALL_append = " linux-firmware". Now I have the necessary firmware to
bring up the WiFi.
3. There is some delay cause in booting that affect the ability to have WiFi
active after boot. I have to wait a few minutes until I see the error and
recovery before doing the ifup wlan0.
dmesg | grep wl12 gives me the following output:
[ 0.396392] vwl1271: 1800 mV
[ 67.167297] wl12xx: ERROR could not get nvs file
ti-connectivity/wl1271-nvs.bin: -2
[ 67.181457] wl12xx: loaded
(once I see the message above I can ifup wlan0 which produces this output below
and WiFi now is working:
[ 135.964355] wl12xx: firmware booted (Rev 6.3.5.0.98)
[ 137.979522] wl12xx: Association completed.
