There was an bug inside of the PLD file used on the PicoMOD-SKIT (starter kit).
It was no problem to use CAN (driver have to be available) but it was not possible to use an CF-Card with the SKIT.
To solve the CF-card problem, it was neccessary to use an new PLD file.
From November 2009, there is used an new PLD file.
Now it is possible to use CAN and CF-Card also on the SKIT.
Attention !
CF-Card is working without problems.
To use the CAN, there have to inserted an CF-Card (memory card) at the same time.
If you design a own carrier board to insert PicoMOD, there is available an application note.
Please use this logik, than CF-Card and CAN can be used independent.
(design alert PicoMOD-Startintf2)
