I have some problem with Arduino uno and asked here, so I have tried to work by my STM32F103C8 as alternative board, and solved my problem by this question:

Arduino Port Not detected and can not run it as root

But now I as seeing that the Arduino port again is not acceptable but I can upload the codes into the STM32F103C8 board, so I asked why this happen ?

Note : I have seen this post which the STm32F103C8 board have some port on Arduino IDE (as you can see below ):

Thank.
