MSP430FR5994: Run in RAMs on msp430fr5994 chips

Part Number: MSP430FR5994

Hi Team,

I am trying to use the run at the RAM function on the MSP430fr5994 launch pad.

I do follow the instruction to allocate memory for functions, but it still has errors. I have no idea, could you help me solve this?

My setting:

Errors:

With kind regards,

Hello Qingyun,

Although the following resources are for different devices, the general guidance will be the same. In particular, the third party write up does a good job explaining the steps. I would cross check the linker changes you have done with these examples.

Also, double check your function size and ensure it will fit in your allocated area.

And with this being an FRAM device, double check your MPU and IPE settings/restrictions to make sure it is allowing for these type of memory changes.
