FDCAN FIFO full

[ChaitanyaParate]

I am using a custom PCB with stm32g474 and I am trying to get the CAN peripheral working. I believe I have everything set up correctly (bit rate, RAM etc) but when I call HAL_FDCAN_AddMessageToTxFifoQ(), FIFO is full error is raised after 3 iterations.

Any help is appreciated.

I agree 100% with mƎALLEm.

I'm still thinking that You have a problem with the physical Bus.

Do You have the possibility to check the signals on the BUS? 

For example with a PC and a Can dongle, or with a oscilloscope.
