C55FMC High blocks unusable

Question asked by Matt Barbour on May 2, 2017

I am unable to read, write or erase any data in the high space blocks. I am using the iSystems WinIDEA debugger which is unable to display any data within the address range of the high blocks, this includes after I perform a flash mass erase through the debugger. I have used the Standard Software Driver v1.1.0 for the MPC5777c. I am able to read and write to low, mid, and 256k blocks without a problem.

I have attached some sample code and drivers that I am having this problem with. 

To recreate:

Start a new S32DS project for the MPC5777C

Set the library for all cores to NewLib

Copy in the attached files and compile
