MSP430F5419A: code executing from RAM with TI library + IAR

MichRFT

Hello,

I want to execute code from RAM for algorithms. Inside this algorithm I am using memset, shift, abs() and division. The IAR IDE uses TI library for theses functions and I have the following warning:

Warning[Ta039]: Call to a non __ramfunc function ("__nounwind memset") from within a __ramfunc function

Warning[Ta039]: Call to a non __ramfunc function ("__nounwind labs") from within a __ramfunc function

Warning[Ta037]: Library call from within a __ramfunc function

How could I specify the tool to put these library functions inside RAM?

Best regards

Michel

Hi Urica,

I request some help from IAR especially for library used and linker commands.

Best regards

Michel

Hi Michel,

The general principle of modifying the linker file is the same. For more IAR-specific details on doing this, I would refer to the these threads [link1, link2]. You can also refer to this IAR tech note on placing a library in RAM [link].

Thanks,

Urica Wang
