S32K342 HSE

Dear Sir：

We are a third-party programmer manufacturer.

The S32K342 programming flow has been completed.

After successfully programming the HSE file, repower on wait 5 seconds, and read 4039_C028h (bit 0) to confirm whether the HSE was successful.

However, I read out 0x000001C0 (bit 0 is 0, HSE Unsuccessful).

What other registers can I read to confirm whether the HSE was successful?

Thanks

Re: S32K342 HSE

Have you installed on virgin device or there were already some attempts to have installed FW before?
Could you provide following information?
SBAF version:
HSE FW version:
MU registers, FSR, GSR, etc:
HSE GPR3:
Is the "HSE_STATUS_INIT_OK" have been wait set to "1"?

In case AB SWAP, multiple resets may be required.

Recently I have discussed installation procedure over following thread:

Hope it helps
