HAL_CAN_RxFifo1MsgPendingCallback has a problem.

[Ukazu]

HI

If the CAN message ID set to FIFO0 is received, HAL_CAN_RxFifo0MsgPendingCallback will be called correctly.

but,
HAL_CAN_RxFifo1MsgPendingCallback is not called even if the CAN message ID set in FIFO1 is received.

The following is strange.

step1
Send CAN message set in FIFO1 from CANoe

step2
HAL_CAN_RxFifo1MsgPendingCallback is not called.

step3
Send CAN message set in FIFO0 from CANoe

step4
HAL_CAN_RxFifo0MsgPendingCallback is called.
After this, HAL_CAN_RxFifo1MsgPendingCallback is called! !
The data received in FIFO1 is from FIFO1 and is correct.

 

Below is the code.

Any help is welcome.

Hi

Additional information.

I monitored FMP1[1:0] of the CAN_RF1R register.
After sending one CAN message from CANoe, FMP1[1:0] became 1. FIFO1 stores pending CAN messages.
FULL1 and FOVR1 were also working correctly.

At this time, FMPIE1 of the CAN_IER register was 1. That is, the FIFO1 message pending interrupt is enabled.

Even with this, HAL_CAN_RxFifo1MsgPendingCallback is not called. Is this a problem with the microcontroller?

HI

 

The vector tables were different for FIFO0 and FIFO1.
I thought vectors were common.
