Mbed Studio
1

I all of a sudden I started getting these linker errors. Just this one project gets the errors, other project based on the same target works. I reverted to a previous build and still get errors (linked properly before commit). I reinstalled Studio and OS 6.13.0, same result.

No networking or TLS usage in the project.

Anybody have an idea where to start looking?

Thanks,
Tim

Mbed Studio 1.4.1
Mbed OS 6.13.0
Target: SNII_HUB_MAIN based on STM32H743ZI

Hey, I am facing the same problem. How were you able to solve this? Thanks in advance

If I remember correctly it had to do with using the .mbedignore file to reduce compile times. I think I ended up adding the following to .mbedignore to get rid of a reference.

mbed-os/platform/randlib/*

Let me know if that helps.
