We are using #NXPS32K388 Microcontroller with its embedded #HSE-B
Please can you help me resolve the following issues:
1. Is there an internal ROM in the HSE to install its firmware or we just use the micro secure PFLASH? (N.B. the attached micro block diagram shows that the HSE has a RAM but no ROM is shown in the architecture)
2. If the HSM firmware update is signed and encrypted, is there enough space in the PFLASH memory (like reserved memory) to decrypt it before moving it to the secure PFLSH or allocated HSM firmware memory location?
Thank you.
