I would like to use MRAM memory of the TWR-MEM board with the TWRK60N512 kit to be able to debug larger programs in RAM. I am using CW10.1, MQX, and PE.
What I would like to know is how to setup the MRAM for use in my program. It is not clear to me how to specify the additional RAM. Modifying the lcf file doesn't work because it gets overwritten and fields in the PE CPU component for external memory are unavailable. Looking in init_hw.c, it appears that the MRAM is not even initialized if PE_LDD_VERSION is defined.
Also is it necessary to remove R14 for the MRAM to work?
