TJA1145 Selective wake up

[CCG]

After entering sleep,ret=SPI_read(0x22); ret=0x28,send a CAN frame with ID 121,the MCU is awakened.

But,After entering sleep,ret=SPI_read(0x22); ret=0x28,send a CAN frame with ID not 121,the MCU cannot awakened.then,ret=SPI_read(0x22); ret=0x30.  COSCS=1,CBSS=0;

and if you follw the previous send a CAN frame with ID 121,the MCU cannot awakened too.

I have the exact same issue on my board. Were you able to fix it?

我看你写的，你是想要什么结果？

怎样才能消除错误帧对特定帧的影响。当进入睡眠后，发送错误帧后，再发送特定帧也能唤醒。而不是只能发送特定帧，发送错误帧后，再发送特定帧就不能唤醒

Furthermore a frame on the bus needs to be free of CRC, stuff and form errors to be a valid WUF.

Any error after the CRC delimiter is ignored and does not invalidate a received WUF.
