Hello Thomas, I am currently unable to establish normal communication with the sja1124 chip. I want to develop a Linux driver adapted to the sja1124 chip, but I can't read the data through the function interface provided by the Linux driver, I want to know if there is any specific pin state when the chip is working normally, can you help me?
