M5StickC usb driver and Catalina
-
@sheepdog this problem from MAC OS FTDI driver , you can try to use WIN10 OS (like using a virtual machine) to upload program. also M5StickC Upload program don't need CP2104 Driver.

@m5stack Thank you for your quick response. I am sure that Mac OS Catalina need a driver. A few days ago I installed Mac OS 10.15.2 form scratch and M5StickC needs the cp210x-driver (M5Stack needs the FTDI driver!).
You can test it. If you connect a M5StickC you see at the directory /dev a file with this name "cu.usbserial-<number>". With connected M5Stack you see "cu.SLAB_USBtoUART" (<- This is the FTDI driver).
My workaround is "Connect G0 pin to GND". That is not nice. Your solution to start a VM is even more complex because all need all my files there.
Yes, I can program M5StickC, but I am looking for an easy way to program M5StickC with short turn around times and easy handling. Normally I used Atom editor with PlatformIO.

@m5stack could you please advise on the best process for getting M5StickC to work and flash via esptool on Mac OS Catalina ?
Also, advise on which driver is needed for M5StickC. Is it the FTDI driver or is it the CP210X driver ?

@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.
