There is an example code in S32DS SDK (flash_partitioning_s32k144). Flash partitioning needs only be done with blank new device or when you need to changes its configuration. Not after every reset.</P> <P>In this mode FlexRAM acts as access point for EEE memory space, and EEE state machine perform flash erase/program operations to NVM (in this mode assigned to E-flash). From user point of view access to FlexRAM is same as access to ordinary RAM.</P> Fri, 13 Dec 2024 16:48:48 GMT https://community.nxp.com/t5/S32K/Flash-Partitioning/m-p/2013746#M44245 davidtosenovjan 2024-12-13T16:48:48Z
