FS23 INIT CRC error

Leex — Mon, 21 Oct 2024 09:26:10 GMT

When I was debugging the system functions of +S32K3x, I found that if the INIT configuration of FS23 in my application program was inconsistent with that of FS23 in the Bootloader program, then when the system woke up from FS23 LPOFF mode, An INIT registers CRC error occurs in the FS233 initialization of both the Bootloader program and the application, causing the FS23 initialization to fail. In addition, if the POR (power on reset) is normal, this situation will not occur. How can I solve this proble

When an exception occurs, I find that INIT CRC error is raised whenever CRC is written

Hello,

Each time you exit the INIT phase, before that, you should confirm the INIT CRC value is written and the value is correct.

Please refer the FS23 AN in secure files to understand the procedure.

By the way, I can provide one file which can calculate the INIT CRC, but I cannot share it here, please open a support ticket.
