CAN interrupts on a 2948

Hi @all,

we are using a LM3S2948 device at 50 MHz clock speed.

This device is currently connected to a CAN simulator on CAN0 which is sending a specific CAN message every second.
Unfortunately we are experiencing duplicate interrupts after startup and a whole lot of them during startup directly after interrupt activation.
Can this be related to the timing issues mentioned in the 2948 errata?
Our interrupt handler is quite similar to the one in the 2965 example which does nothing to adress the issues mentioned in the errata while running at 25 MHz.
Is there any example for a CAN interrupt handler circumventing the timing problems?

Best regards,
Ralf
