Resolution is easiest to change from u-boot.

Are you using a serial debug console?

You can either change the kernel arguments to inclued your resolution (mxcfb0 stuff), just have 320x240 there and it will use the CVT timings for that mode.

If you want to hard-code the resolution in u-boot, you can edit the source in include/configs/wandboard.h

(Hard to give specific instructions, since we have a few different u-boots, where the settings are different)
