Switch the debugging console serial port from LinFlex0 to LinFlex1。Then test it on the system board, and found that loading the BL31 image failed in the BL2 stage. Further analysis found that after sending CMD17, the value of the register INT_STATUS (402F_0000h + 30h) is 28000h, and a Command CRC error occurred. Combined with the RM of S32R45, the CRC check is completed by the uSDHC module, and the software ATF does not participate in the CRC calculation, and the CRC check result can only be obtained through the register.
