dear NXP expert:

I got a problem after installing HSE firmware.

I installed the HSE firmware by the project provided from FAE and the HSE seems be installed successfully by the information in Access HSE service by MU_B channel_0 - NXP Community

now I download the bootloader code (developed by our side) and the boot can runs only about 9 seconds and it will reset and I check the reset reason and it shows that HSE trigger the reset .if the boot runs in a hardware without HSE firmware installed, it will runs ok.

I download and debug the boot by PE and the S32DS would erase 0x1B000000 by default option.

I checked the content in 0x1B000000 by PE and it shows it has been written which is not the 0xFF, the content in utest shows the HSE has been activated .

Hi @yin_qiu

The HSE SWT RST issue is typically caused by an incorrect clock configuration. For further assistance, please refer to the following post: HSE provides RSP_NOT_SUPPORTED response. It contains valuable information that should help resolve the problem.
