I am using STEVAL-ILD004V2 source code for dimmer. I can compile using my ST Develop using STM8 cosmic compiler when no change. But, when I change MCU to STM8S103F3P. I will have this compile problem below. Regards, Walter

Code / data size overflow.

Try optimization, a better toolchain/compiler, or a MCU with more memory resources.

Reading and interpreting toolchain console output is a crucial skill - consult compile help pages and tutorials.

Thanks, originally working in STM8S103F2P. But when I change to bigger ram chip STM8S103F3P, already have the problem.

Difficult to assess without code.

I would check the map file, to see what happens, i.e. what objects() cause the problem.

".bss" is usually for non-initialized objects (variables).

This section could be declared smaller on the second MCU, even with greater RAM size.

I't s several years ago when I last did a project for a STM8 ...
