When I select “variant”: “EEXTR_F030_V1” for stm32f030c8t6 I get usb related errors EEXTR_F030_V1_errors - Pastebin.com
If I set “variant”: “stm32f0” I get errors related to variants.h variantsh_error - Pastebin.com
What do I need to fix in the json file of the board or which variant should I choose?
