HSE firmware flash

Hello I'm using s32k324 board and I'm trying to flash hse firmware
I have some questions.

1. Is the flash method shown in the 데모 demo release notes the right way to flash hse to the board?

2. If I want to flash the hse firmware, does the debugger have to be trace32? I'm pemicro. According to the demo release notes, it only shows that I used trace32. And .cmm is only supported on trace32.

3. I'm using a pemicro debugger, how do I flash hse firmware on the board?

Hi @minjaekang99

HSE DemoApp requires Trace32 debugger. But we have also these HSE demo examples:
https://www.nxp.com/webapp/Download?colCode=S32K3_HSE_DemoExamples
In fact, it’s HSE DemoApp ported to individual simple SW examples and you can use any debugger to run it.
After installation of the package, you can find this example:
c:\NXP\S32K3_HSE_DemoExamples_1_0_0\S32K3_HSE_DemoExamples\Device_Configuration\S32K344_HSE_FW_INSTALL\
Follow included readme file. It's necessary to update the paths to HSE firmware pink file.

HSE firmware can be installed by three methods - by default location, by IVT and by MU. It's described in HSE-B firmware reference manual (section "3 HSE Firmware Installation") which can be downloaded from :
https://www.nxp.com/products/S32K3
You can find it in section Documentation -> Secure Files.
