I2c in different versions of STM32CubeIDE does not work as should.

[HAhme.1]

Hello,

I have an old project which is on an older version of STCubeMX firmware, and once I migrate it to the new firmware, it stops communicating with the I2C correctly. Is there a reason for this? And how can I possibly fix this?

I'm using the STM32L4RET chip and I've attached the pop up message that comes up to me when I migrate.

It's most likely a bug with CubeMX or the code generation process. I would diff the main.c file before/after the migration, and if that doesn't lead to relevant differences, other files.

I'm doing that right now, but it's a bit long and tedious. Is there no other way because I'm facing a deadline.

Thanks!

You could pay someone else to do it. You could write your own code so you're not restricted to what CubeMX outputs. You could avoid upgrading/migrating to newer versions unless absolutely needed, and plan for some time to find and fix issues that arise.

Maybe that's the price of updating the build tool during the development of the project, I already noticed this type of problem with Ethernet and USB Host.
