Dear STM32 support,
I am working with a STM32F103 device.
CAN FIFO_0 is working fine alone.
CAN FIFO_1 is working fine alone.
But when configuring both CAN FIFOs to work together, sit eems that FIFO_1 is not receiving any message.
Both FIFOs have equivalent filters, I mean, filters with different indexes,
but the masking itself are the same for both FIFOs.

Questions are:

1) Is it posible to configure and make work both CAN FIFOs together?
 If yes:
 2.1) Are there any  special tricks to take into account?
 2.2) When configured together, does FIFO_0 has higher priority tan FIFO1?

Thanks a lot for your help.
