Error in STM32F401RC6 compilation

[phalgunimondal]

I am using STM32F401RC6 controller and this core https://github.com/stm32duino/Arduino_Core_STM32 not sure why below compilation error comes

arduino-cli compile -b STMicroelectronics:stm32:GenF4 dmd_monochrome

I am using STM32F401RC6 controller and this core https://github.com/stm32duino/Arduino_Core_STM32

Hi The library is incompatible with the core you used. Please use a edited Robert Clark's core? as stated in the Readme

[phalgunimondal]

How to use Robert Clark's core because no index.json found EX:(https://github.com/stm32duino/BoardManagerFiles/raw/main/package_stmicroelectronics_index.json)

kindly refer documentation

[board707]

see the Wiki https://github.com/rogerclarkmelbourne/Arduino_STM32/wiki/Installation

For STM32F4 boards use a local clone of the Clark's code from this repo: https://github.com/board707/Arduino_STM32/tree/lto_for_c6

hi, friend, after compilation project DMD_STM32 the same errors, Do I have the same problem as you solved this problem?

[board707]

Hi, you used incompatible stm32 core. To solve the issue please read my answer just above your message.
