MSP430FR6043: Shift LEARAM to RAM section

Ajay Matariya
Prodigy 30 points

Part Number: MSP430FR6043

Hi, 

    I am currently working on the MSP430FR6043 and i am short of the RAM and FRAM in order to implement my application stack. MSP430FR6043 has 8KB of LEARAM and 4KB traditional RAM. Currently my application only usage the 3KB of LEARAM and remaining 5KB is free. Is it possible to shift some LEARAM section to traditional RAM section using the linker script.

Thanks in advance.

Thanks & Regards

    Hi Ajay,

    I have gone through datasheet, and it descirbes below:

    The LEA requires MCLK to be operational; therefore, LEA runs only in active mode or LPM0. While the LEA is running, the LEA data operations are performed on a shared 8KB of RAM out of the 12KB of total RAM (see Table 9-52). This shared RAM can also be used by the regular application. The MSP CPU and the LEA can run simultaneously and independently unless they access the same system RAM.

    According to the description, you can individually divide your LEARAM region and please make sure that LEARAM should not simultaneously access the same region. 

    If you have any feedback, please kindly let me know.

    Best Regards

    Sal
