I am using the Kinetis MK20DX256VLQ10 with CodeWarrior 10.6.4 with all current updates.
Processor Expert is configured for 512 bytes of EEPROM, 50/50 split and all 256K for EEPROM backup (0x2506).
I am able to partition this correctly when downloading with CodeWarrior and PROGACMP using a MultiLink Universal FX.
I tried putting a call to Cpu_SetFlexRAMFunction( FlexRAM_AS_EEPROM ) prior to calling Cpu_SetFlexNVMPartition() to insure that the FlexRAM is set for EEPROM and that function fails also. Both with the Access Error flag set.
I have single stepped the machine language and it looks like everything is setup appropriately.
I have researched this on the forums and haven't found an answer. This is not a stack overflow problem.
I have seen this work on single step and i am trying to recreate the successful procedure.
Thank you for your help.
