TMS320F28379D: Change access to CAN from CPU1 to CPU2 don't work.

Hi,

I have two project one runs in CPU1 and the other one in CPU2. To update both programms I use the CAN module. For the Programm in CPU1 the update works fine.

When I change the access for the CAN module in CPU1 to CPU2 the communication via CAN don't work in the CPU2. I changed the access with the following code part:

In CPU1:

SysCtl_selectCPUForPeripheral( SYSCTL_CPUSEL8_CAN, 2,  SYSCTL_CPUSEL_CPU2);

I use the CANB module over the output pins 12 and 17 from the Launchpad.

Have anybody an Idea for this problem?

Thanks for your help.

Best regards,

Markus
