These are brief instructions on how to add support for CF adapters to
|
|
custom designed PXA boards. You need to set the parameters in the
|
|
config file. This should work for most implementations especially if you
|
|
follow the connections of the standard lubbock. Anyway just the block
|
|
marked memory configuration should be touched since the other parameters
|
|
are imposed by the PXA architecture.

Another important point is that maybe you have to power the pcmcia
|
|
subsystem. This is very board specific, for an example on how to
|
|
do it please search for CONFIG_EXADRON1 in cmd_pcmcia.c
