The problem I am having is that there is code like Cmd_SetFlexRAMFunction_Init() in FTFL_PDD.h, but I can't find any way to enable or use it from either of the (KDS) Processor Expert IntFLASH or FLASH_LDD components. Those two components don't seem to do any FlexRAM setup either, although I have successfully set up the FlexNVM partitioning in the CPU component, and Component Inspector shows those partitioning values for the FLASH_LDD component.
So to sum up, I can't find any support for configuring and using FlexRAM; it seems as if the FlexRAM support is there "under the hood", but it's not available through the components. I can probably figure out how to hack it, but I'd prefer to use PE-generated code :-)
I'm developing for a Kinetis K10 -- MK10DX128VLF5.
