Don't despair, you are on more solid ground with the Sony LCD since the
path has been blazed before you by lots of other people and we know it
works with the gumstix You don't need anything "apollo"; apollo is an
internal name for a display controller ASIC which can only drive an SVGA
E Ink screen. Things I would check if I were you:
- check with a scope to see that all the LCD lines out of the gumstix
are doing what you think they should be doing
- send the list the output of the following:
# pxaregs LCCR
- send to the list a mapping of what you have each of the 22 pins of the
LCD flat flex connected to
- make sure the enable signal to the LCD is set correctly
- make sure you are supplying both the 3.0V and the slightly higher
voltage on the correct pins of the LCD
- make sure you didn't mirror the connector pins somewhere along the line
- check with a scope on the PCB in back of the sony LCD that you can see
the various LCD controller signals
