Reading through the docs for the STM32 G474 FDCAN TX sections, it seems like if FDCAN is in FIFO mode, there is no way to cancel a pending message. The message can only be dequeued from being sent. If this is the case, how should one handle the case of the currently TX'ing message not ever being acked? In this case, if the message is never acked, it cannot ever be dequeued and the FDCAN TX will essentially be stalled for any other messages.
I do see the cancellation functionality, but it seems as though none of it applies to FDCAN in FIFO mode?
