[BUG] Error: Unknown environment names 'STM32F103RC_btt_512K' ---- SKR Mini E3 V2 Board compile error #22177

Closed tijoer closed 3 years ago

Did you test the latest bugfix-2.0.x code?

Yes, and the problem still exists.

Bug Description

Hi, I cannot compile with plattform.io, as I get this error. It seems to be that the variable was removed. I am now unsure which one to use. I could use the following for my SKR Mini E3 V 2.0 board. All of them sound fine to me. Bigtreetech uses STM32F103RC_btt_maple in their example configuration, but I heard that this is an error. Now I am completly confused.

I think the var should not have been removed, but marked as deprecated instead with a documentation how to migrate.

Bug Timeline

new

Expected behavior

Either one:

The compiling works fine or the variable had been marked as deprecated and the compiler would link the documentation to the migration information.

STM32F103RC_btt_512K was a horrendous hack, and should never have been allowed. If you have a STM32F103RC it only has 256K of Flash, using more than that is not recommended, Its not meant to be there, has never been tested, is quite likely a failed STM32F103RE they they sold as the lesser chip. The STM32F103RE is the chip that officially has 512K. You use STM32F103RC_btt or if you actually have a STM32F103RE chip STM32F103RE_btt

maple is legacy, will be removed soon _USB is if is you want to mount your sdcard as a usb drive.

Thank you very much for your helpful explanation, as I am new to embedded development and I am still quite lost sometimes.

However would there be a way to add a proper deprecation warning? If you could guide me to an example of other deprecation warnings I could try to work on a pull request.
