For Bert Sesam :

What programmer do you use ?
Dit you reprogram a -CA into a -UA ?
Can't test the -CA bootloader due to the CAN INIT FAIL problem with the VECTOR CANCARDX.

The bus consists of a target board, the demo-board from ATMEL and the CANANLYSER from Vector (only for monitoring) The target and analyser are fully opto-isolated. The bus is properly terminated. When sending CAN messages from the demo-board, the analyser works fine.
