M5StickC usb driver and Catalina

m5stack

@tcruse first , on some Mac PC, M5StickC cannot upload program properly.

the solution: When programming, short the G0 to GND using the DuPont line.

and , all most PC don't need driver with M5StickC. But some old PC System need install FTDI driver.

FTDI driver is for M5StickC, CP2104 driver is for M5Stack Core ( like Fire BASIC M5GO)

@m5stack Yes, I swapped the drivers. You can check it at Apple menu, systemreport and USB.

If I connected a M5Stack I saw:
If I connected a M5StickC I saw:

You can check the loaded drivers and their versions in terminal with "sudo kextstat".

I noticed that sometimes M5Stack didn't not work without "short the G0 to GND". I think that is a timing-problem at Catalina and esptool.py. It is not a problem of M5Stack- or M5StickC-Software.

It may make your firmware lose and make it unusable, so if you are willing to take this risk, you can chat with me in private and I will give you a link to download the tool @sheepDog @world101
