[Buildroot] Fwd: Fwd: Fwd: Fwd: [PATCH v3] linux: add fbtft kernel extension

[Lou Crittenden]

As for the drivers starting up @ boot, I followed the advice of this page:
http://unix.stackexchange.com/questions/59018/create-and-control-start-up-scripts-in-busybox
(I have busybox enabled) and attempted to make a simple script in the
/etc/init.d/ folder called fbtft, but no go.

here it is (and I did make sure to run chmod +x on it to make it
executable):

#!/bin/sh

exec insmod /lib/modules/3.12.28/kernel/drivers/video/fbtft/fbtft_device.ko
name=waveshare32b rotate=270

exec insmod /lib/modules/3.12.28/kernel/drivers/input/touchscreen/ads7846.ko
