Customer says:
 
I set the resolution back to 1024x768 and the program runs fine with no error messages.

As for the sloginfo there is only that one message:

Jan 01 00:00:00 2 8 200 io-display: driver doesn't support, or not
configured for "argb1555" at 1280x480, 60Hz
 
It's not clear to me how the jade.conf file precisely matches the mode that is specified in display.conf. Where does 
argb1555 fit in ?
 
If it is hdp and vdp, along with refresh, it might be nice to document that.
 
Are these files any help ?
 
Here's the non-working display.conf and jade.conf .

# Board-specific options:
