DTR line management - macOS Big Sur

[mutty75]

Hi,

I'm facing some problem during my ESP32-WROOM dev board programming via Eclipse IDE running on macOS Big Sur:
I can upload firmware code into board only if during programming I manually press some timer BOOT button.
Otherwise programmer goes in timeout.

I checked with scope DTR and RTS signal and seems that while RTS is correctly managed during programming, DTR line remains high all the time.
This happens only if I program the board under maOS Big Sur.
If I try to do this on the SAME PC, using the SAME hardware setup with the SAME project but from a Windows10 virtualized machine (with Fusion), both lines works fine and programming is done correctly with no need of manually pressing BOOT.

Someone is facing the same ?? There is some fix for this ??

Thank you.
