[meta-freescale] Freescale i.MX6 SabreSD vs 1024x768 over HDMI

[zboszor at pr.hu]

Hi,

how can I set 1024x768 for a HDMI-connected monitor for the board in
$SUBJECT?
Originally, I had this:

setenv video mxcfb0:dev=hdmi,1920x1080M at 60,if=RGB24,bpp=32
setenv mmcargs 'setenv bootargs console=${console},${baudrate}
root=${mmcroot} video=${video} consoleblank=0 vt.global_cursor_default=0'

and all was well, fullHD is the native resolution of the monitor.

However, if I change the "setenv video ..." line like:

setenv video mxcfb0:dev=hdmi,1024x768M at 60,if=RGB24,bpp=32
or
setenv video mxcfb0:dev=hdmi,1024x768 at 60,if=RGB24,bpp=32
or
setenv video mxcfb0:dev=hdmi,1024x768,if=RGB24,bpp=32
or
setenv video mxcfb0:dev=hdmi,1024x768,bpp=32

then I get a 640x480 resolution. What is the proper incantation to set
1024x768?

Thanks in advance,
