I tried using MCAL to deliver SPI drivers for read and write operations on TJA1145, but the data I received was always fixed and I'm not sure what caused it. Can you give me some guidance? Thank you very much

From your oscilloscope snapshot, I cannot check if the timing and format of the SPI message is correct.
A very common problem is that timing parameters are violated, so please make sure everything is in accordance with the following specs:
