Installation
- Launch Buildroot configuration
# make menuconfig
and choose SDL package in:
you can choose packages like SDL_Imagae too; then save your configuration
- Regenerate your rootfs
# make
and reflash it on your board
Configuration
Our SDL version is using the FrameBuffer interface and so it's very important to have a /etc/fb.modes file up to date with the framebuffer parameters supported by your configuration (otherwise SDL try to use the VESA parameters which are may misprogram the i.MXL LCD controller).
For example for the Sharp LQ057, activate in /etc/fb.modes:
mode "320x240-176" # D: 16.000 MHz, H: 43.836 kHz, V: 176.047 Hz geometry 320 240 320 240 16 timings 62500 9 27 0 7 9 2 rgba 5/11,6/5,5/0,0/0 endmode
By default the Armadeus LCD (Microtips) parameters are used in /etc/fb.modes.
Usage
