Title: Manage two screen : LCD + HDMI
Post by: Alex293 on October 03, 2014, 01:42:20 PM
Hi guys,

I manage to have LCD + HDMI working but with poor resolution for my HDMI screen and i'm forced to have LCD as screen 0 and HDMI as screen 1. My problem should be solved by increasing the size of the frame buffer but my extra kernel argument sunxi_mem_fb=128 doesn't seem to be effective. When i debug Uboot uEnv is read and arguments are passed to the kernel but it have no effect.

DO someone have any clue or an uEnv.txt working with sunxi frame buffer memory working ?
