Need support on HSE CMM script understanding

We need to be able to erase all key slots in the HSE. Please implement a service that allows us to do this. We currently have the following services:

READ_FW_VERSION
FW_INSTALL
FW_ERASE
NVM_ERASE
FLASH_ERASE

but none of them erases the key slots in the HSE.

Please let us know if you need more details.

I suppose your question points to HSE_DEMOAPP.

There is a script EraseKeys.cmm for this purpose.

Is there a repository on the NXP website that hosts all the CMM scripts? Where do we see all of them?
Does this CMM script apply to both S32K388 and S32K344?

Thanks!

No. I am not aware anything like that. CMM scripts you may find in the mentioned example application.
