Code size exceeds the limit license size on Keil: how to handle this issue?

[stm32beginner2024]

Test\Test.axf: error: L6050U: The code size of this image (34476 bytes) exceeds the maximum allowed for this version of the linker.

How can I reduce the code size? Where can I download other ARM compilers? I use V6.21 and use Keil (Non-commercial use license) Does anyone have a site 🙂

Hello,

I think it seems you're using a limited license on size of 32KB for Keil.

Did you try to optimize the code on size?

[stm32beginner2024]

And where can I make the size smaller?

[SofLit]

To optimize on size click the buttons on these steps.

On Step 3 you need to uncheck the box "optimize for time".

Does it answer your question?

Well CubeIDE is going to install a complete GNU/GCC toolset, perhaps you can point to the install directories for that?

I found these with a 5 second Google search

I've used Yagarto, GNU C tools downloads and make

You're not going to get cracks here.

Why not use the STM32CubeIDE (which uses the GCC compiler)?

It's free and unlimited !

EDIT:

Note that the optimisation options are often limited on free versions of Keil ...

>>Note that the optimization options are often limited on free versions of Keil ...

But still often better than GNU/GCC

Dead-Code elimination and Link-Time Optimization missing.

For ST's Cortex-M0(+) platforms there's a free Keil Licence.

Honestly I'd have preferred they did this for the others too rather than buy an entire IDE company

You can ask for a time-limited Keil evaluation (~ 2 weeks IIRC) but then either buy a license or port the project to GNU or other freebie toolchain - this can be even the Keil Community edition.
