Hello every
I want to increase STM32G473 FDCAN Tx buffer and Rx buffer size,
In STM32G473 datasheet >> "A 3-Kbyte message RAM memory implements filters, receive FIFOs, receive buffers, transmit event FIFOs, transmit buffers. This message RAM is shared between the threeFDCAN modules."
In my project, I used three FDCAN（FDCAN1 FDCAN2 FDCAN3），However, after testing, if there is no delay, each FDCAN can only send a maximum of 3 data.This seems to match the SRAMCAN_TFQ_NBR parameter.But when I modified this parameter, the data sent became very strange, and the CAN analyzer could not receive normal data.
Does anyone know how to increase the tx buffer size of FDcan? Besides this, I would also like to know how to increase the size of the rx buffer
If you have any questions, please feel free to discuss with us，Thanks！
