貌似手册上没说，怎么搞都只有FDCAN1_IT0_IRQHandler中断进入。谢谢！

仅FDCAN1支持TTCAN时间触发通信,而FDCAN2不支持。 92.3.3 FDCAN支持的最高速度 经典CAN是1Mbps,CAN FD最高2Mbps,CAN FD-SiC是5-8Mbps,CAN XL是10Mbps。 92.3.4 FDCAN的主时钟选择 FDCAN1和FDCAN2支持三种时钟源HSE,PLL1Q和PLL2Q,我们这里选择的PLL2Q输出20MHz。

Even with host transmitting CAN data, the function: void FDCAN1_IT0_IRQHandler(void) is never called. Hello@RickN, The FDCAN2 TX is initially disconnected inMB1397-G474EMC-B04Board revision, SB5 is open by default, Could you please solder the SB5 location on the board. ...
