      No solution with Catalina did work for me. Only the programming with Windows 10 was working.

      Which driver did M5StickC need? A Silicon Labs CP210x-driver?
      I installed CP210x Version 5.2.4 and I used Catalina 10.15.3 (19D49f).

        As far as I know the esp32 pico, which is inside the stickC does not use the cp210x drivers. Some have reported using standard ftdi drivers to interface with the device. I'm afraid I dont have OS Catalina to test

          @lukasmaximus Thank you for your help. In the meantime I tested with Catalina Version 10.15.2 (19C57) and with the drivers from FTDI. I can not program the M5StickC, but the Arduino Monitor did work!

          I found the problem: The M5StickC didn't change to upload mode!
          I connected a small button between GND and G0 at the 8-ext Pin connector and I pressed the button if Arduino like to upload ("Connecting........_____...."). The workaround worked fine.

            Is there any other way to change M5StickC to upload-mode? Ist isn‘t nice to change the connector every time I like to upload a new program. I used a joystick-modul and my upload-modul.

              I can confirm that the workaround "Connect G0 pin to GND" works for me on Catalina 10.15.2. I am now able to write to the m5StickC wheras before it was stuck connecting eventually throwing the error "A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header". I am able to reproduce this on two m5StickCs. It's worth noting this is without any 3rd party drivers and after only following the steps given here - https://docs.m5stack.com/#/en/quick_start/m5stickc/m5stickc_quick_start_with_arduino_MacOS

              Has there been any progress on resolving the issue?

                In the meantime I tested three M5StickC and can not program anyone without "Connect G0 pin to GND". I changed from Arduino to esp-idf and got the same issue.

                After some analysis, I separated the problem: I think the esptool.py didn't work correct with the cp210x drivers. The critical part is:

                  def _connect_attempt(self, mode='default_reset', esp32r0_delay=False):
                    """ A single connection attempt, with esp32r0 workaround options """
                    # esp32r0_delay is a workaround for bugs with the most common auto reset
                    # circuit and Windows, if the EN pin on the dev board does not have
                    # enough capacitance.
                    #
                    # Newer dev boards shouldn't have this problem (higher value capacitor
                    # on the EN pin), and ESP32 revision 1 can't use this workaround as it
                    # relies on a silicon bug.
                    #

                    # with an intermediate device to the ESP32
                    if mode == "no_reset_no_sync":
                        return last_error
                
                    # issue reset-to-bootloader:
                    # RTS = either CH_PD/EN or nRESET (both active low = chip in reset
                    # DTR = GPIO0 (active low = boot to flasher)
                    #

                        time.sleep(0.1)
                        if esp32r0_delay:
                            # Some chips are more likely to trigger the esp32r0
                            # watchdog reset silicon bug if they're held with EN=LOW

                            time.sleep(0.4)  # allow watchdog reset to occur

                def connect(self, mode='default_reset'):

                    print('Connecting...', end='')

                    last_error = None
                
                    try:
                        for _ in range(7):
                            last_error = self._connect_attempt(mode=mode, esp32r0_delay=False)
                            if last_error is None:
                                return
                            last_error = self._connect_attempt(mode=mode, esp32r0_delay=True)
                            if last_error is None:
                                return
                    finally:
                        print('')  # end 'Connecting...' line
                    raise FatalError('Failed to connect to %s: %s' % (self.CHIP_NAME, last_error))
                

                The esptool.py used reset with DTR and RTS and I suspect this part did not work correct, because any print of '.' or '_' showed a (fatal) error.

                My short test for all existing ports showed the error:
                $IDF_PATH/components/esptool_py/esptool/esptool.py chip_id

                  @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.

                          1. If I connected a M5Stack I saw:
                            0_1577975601066_M5Stack.jpg

                          2. If I connected a M5StickC I saw:
                            0_1577975705966_M5StickC.jpg

                          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.
