SDL Development

SDL installation

Launch buildroot configuration

# make menuconfig

and choose SDL package in:

and save your configuration

Then regenerate your rootfs

# make

and reflash it on your board

Our SDL version is using the FrameBuffer interface and so it's very important to have a /etc/fb.modes file updated with the framebuffer parameters supported by your configuration (otherwise SDL try to use the VESA parameters which are perturbating i.MXL LCD controller).

For Sharp LQ057 put 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
