CCS/MSP430FR5949: how to switch from FRAM to RAM

Hi,

You need to modify linker file (.cmd) in your project if you would like to Divide FRAM as RAM to use.

Some code maybe useful to you :

In cmd file : ( this example is to allocate 0.5K of FRAM as RAM, IC : MSP430FR2311. )

)

MEMORY : 

RAM : origin = 0x2000, length = 0x400
RAM2 : origin = 0xF100, length = 0x200
FRAM : origin = 0xF300, length = 0xC80

SECTIONS :

.bss : {} > RAM | RAM2 /* Global & static vars */
.data : {} > RAM | RAM2 /* Global & static vars */

 More details about how to modify, you can refer to this file :
