imx8dx flexcan always getting error using TJA1057G3

HI

When imx8dx uses TJA1057G3, it always fails, and it often bus off when sending. When reading data, imx8dx can_RX -- TJA1057_RXD, the logic analyzer captures data and shows that there is no ACK. I would like to ask, is imx8dx good enough for the device TJA1057G3, why does my device always have problems. The circuit is also from the documentation of TJA1057G3.

Thanks
