MSP430FR5994: How to use malloc by msp430 gcc?

Qingyun Guo

Part Number: MSP430FR5994

Hi Team,

I am trying to use malloc by msp430-GCC-8.2.0. Btw, the compiler looks for the malloc function in arm-GCC automatically. The error alerts are like the following picture. So, how can I handle it? Or, has msp430-gcc corresponding malloc functions?

With best regards,

Gaosheng

You are including stdlib.h, right?

Yes, I include the file. Any problem with it?

The inability to find mspyabi_mpyi means that the linker has not been told where to find things like glibc. It might not even be told to link any of the C runtime. This is a problem with your makefile.

You appear to be using cmake which I know absolutely nothing about. You will have to consult its documentation to find out how to use it.
