CubeIDE 2.1.1 wrong linker script memory definitions for STM32C562RE

Kraal · ‎2026-03-31

Hello,

I just downloaded STMCubeIDE 2.1.1 to generate a simple project for a Nucleo-C562RE board.
I am not using CubeMX2 (for various reason, that is not the point).
The default empty project generated for STM32C562RE by the IDE has only 1 SRAM element with a size of 64K, instead of 2 SRAM elements of 64K each.
FLASH size is correct though.
Out of curiosity, if ST were to push a fix for this kind of bug, would it be a new IDE release ? or could it be a STM32C5 pack update only ?

Would be interesting to know if CubeMX2 does create correct linker files ... ?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

I have tested with VSCode and the STM extension, and there the linker script has the correct value of 128K (albeit it is one block of 128K and not 2 blocks of 64K).

The writing differs as well, in CubeIDE size is given as "64K", while in VSCode it is "0x20000" which is less user friendly.

So I believe that MX2 would give the correct linker script (but I did not verify as I don't want to install MX2 just for that yet).
