Currently we are debugging the MC33774 encountered: MC33774 response data error problem, the specific problem is in the MC33774 wake up after the completion of the configuration address and then read the contents of MC33774 register 1h, MC33774 response data occasionally correct see the third picture, most of the response data error see the last picture, and the error is not regular, we use the SPI baud rate is about 1.6M, the MC33774 response baud rate is 2M. The SPI baud rate we use is about 1.6M, and the baud rate used by MC33774 is 2M. The program used is the shifted value MC33774_MC33664_example_S32K344_DS __2__AFE__Working, every time the program goes to the MC33774_CDD_BCC_SWC_Init_Slot4 function the received data is wrong, only occasionally correct. The program we are using is the MCU is GD32A503 and sends the SPI to daisy chain to MC33774 via MC33664. for the specific problem you can look at the following pictures
