S32K344-Memory configuration after HSE_B firmware usage feature flag is enabled

[Simon-Liu]

Hello：

I found in the section [32.3.1.2 Configuration details when the HSE_B firmware usage feature flag is enabled] in RM that the Reserved area, Application flash memory area, and Application data flash memory area have all been reduced. What data are stored in these areas after the HSE firmware is installed and used?

BestRegards,

Simon

You'll find out when you download HSE_B Firmware Reference Manual.

It is a secure file, so following procedure is needed to follow unless you have already done it before:
