Why does the CAN transceiver in UJA1076 not work?

Question asked by 玮 卫 on Jun 29, 2017

Hello, here is the situation. Watchdog is disabled by pulling PIN WDOFF to +5V. Through SPI (MC=11), V2 is +5V, which can be measured on PIN V2. Baud rate of the Sending uC and the receiving uC is both 500k. But the receiving uC can not receive CAN message. The sending software is OK, because when I replace UJA1076 with UJA1050, the CAN communication is OK. What can go wrong? Thanks very, very much in advance for helping!!
