FD_CAN How to reset error counter

[Aeroiiv]

In the FD_CAN register, there is a CEL[7:0]:, REC[6:0]: and TEC[7:0]:,

The CEL register is not being reset on read and goes into the Bus-Off mode.

Do I need to also reset the REC and TEC register?

I am currently using the HAL_GetErrorCounter() function to read the register.

Hello,

You need to reset the FDCAN peripheral to reset REC[6:0] and TEC[7:0].

In order to reset the FDCAN peripheral without power cycling the system;

I am currently calling 

HAL_StatusTypeDef HAL_FDCAN_DeInit(FDCAN_HandleTypeDef *hfdcan)

and the reinitializing using 

static void MX_FDCAN1_Init(void)

 

Are there anything else specific that needs to happen, within the DeInit function it only seems to disable the interrupt line CLEAR_BIT(hfdcan->Instance->ILE, (FDCAN_INTERRUPT_LINE0 | FDCAN_INTERRUPT_LINE1));

Do I also need to deinitlize the clock as well?

Hello,

You need to reset FDCAN peripheral by RCC in HAL_FDCAN_MspDeInit(): 

__HAL_RCC_FDCAN_FORCE_RESET();
__HAL_RCC_FDCAN_RELEASE_RESET();
