Hi, I'm tring to write my program on a Mikrobus Clicker 2 (STM32F407VG) from the Software STM32CubeiDE with a mac. then I create a project and connected my board on my ST-LINK/V2.
I configured Pins and set As Serial Wire. and the Debug As SWD.
I got this 2 errors (Alternate with same configuration):
