Hi,

 

    I built a jb_4.2.2_1.1.0 android image on i.MX6 sabre SD board. By using the default boot parameter, it works without any problem.

U-Boot > setenv bootargs console=ttymxc0,115200 androidboot.console=ttymxc0 vmalloc=400M

 

init=/init video=mxcfb0:dev=hdmi,1920x1080M@60,bpp=32 video=mxcfb1:off video=mxcfb2:off

fbmem=28M androidboot.hardware=freescale

U-Boot > saveenv

 

However, I'd like to set lower resolution to output to HDMI, and I tried the following command, but it does not work. It results in totally corrupted image. Is there anyone who knows how to enable 1024x768x16bpp mode? Do I need to change some source code before building the image?
