Errors found on STEVAL-OET003V1 board documentation for STM8AF5288
The CANH and CANL signals are reversed on the DB9 connectors. The schematic shows CANH from the TJA1043 driver chip going to pin 7 of the DB9, and CANL going to pin 2. This is the standard for use of DB9 connector on many CAN devices. In fact, the signals are reversed due to board layout. It is very obvious when you trace the signals on the board. Very unfortunate when you are trying to use this board to evaluate CAN with STM8AF5288 MCU!!
