Boards Help Please

I ran a sketch to change a board name and I can’t find that script again. It originally was STM32F103RE. I thought I needed it to be STM32F103RET6. I was wrong and now I can’t compile. Can you help me?

See PlatformIO Registry. You mean board = genericSTM32F103RE?

Yes, that is what I meant.

I need STM32F103RET6_creality. It is not listed as a board in Platformio.

Of course, because it’s environment custom environment based Marlin.

          #
          # Creality (STM32F103RET6)
          #
          [env:STM32F103RET6_creality]
          extends                     = stm32_variant
          board                       = genericSTM32F103RE
          board_build.variant         = MARLIN_F103Rx
          board_build.offset          = 0x7000
          board_upload.offset_address = 0x08007000

“STM32F103RET6_creality” is not a valid value for board = .. but just an enviornment in Marlin’s platformio.ini that links to genericSTM32F103RE, and a custom variant implementation.
