Err yeh cold boot the mac it is very susceptible to the unavailable resource issue. And yes press the reset button on the core2 the time period is a fraction of a second and took me over 20 tries to do it.

Thanks @ajb2k3 I tried this earlier too, these are the results of trying that... any suggestions? esptool.py v3.3.2-dev Serial port /dev/tty.wchusbserial54FC0182651 Traceback (most recent call last): File "/Applications/M5Burner.app/Contents/Resources/packages/tool/serial/serialposix.py", line 265, in open self.fd = os.open(self.portstr, os.O_RDWR | os.O_NOCTTY | os.O_NONBLOCK) OSError: [Errno 16] Resource busy: '/dev/tty.wchusbserial54FC0182651' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/Applications/M5Burner.app/Contents/Resources/packages/tool/esptool.py", line 5399, in <module> _main() File "/Applications/M5Burner.app/Contents/Resources/packages/tool/esptool.py", line 5392, in _main main() File "/Applications/M5Burner.app/Contents/Resources/packages/tool/esptool.py", line 4699, in main esp = esp or get_default_connected_device(ser_list, port=args.port, connect_attempts=args.connect_attempts, File "/Applications/M5Burner.app/Contents/Resources/packages/tool/esptool.py", line 110, in get_default_connected_device _esp = ESPLoader.detect_chip(each_port, initial_baud, before, trace, File "/Applications/M5Burner.app/Contents/Resources/packages/tool/esptool.py", line 363, in detect_chip detect_port = ESPLoader(port, baud, trace_enabled=trace_enabled) File "/Applications/M5Burner.app/Contents/Resources/packages/tool/esptool.py", line 320, in init self._port = serial.serial_for_url(port) File "/Applications/M5Burner.app/Contents/Resources/packages/tool/serial/init.py", line 88, in serial_for_url instance.open() File "/Applications/M5Burner.app/Contents/Resources/packages/tool/serial/serialposix.py", line 268, in open raise SerialException(msg.errno, "could not open port {}: {}".format(self._port, msg)) serial.serialutil.SerialException: [Errno 16] could not open port /dev/tty.wchusbserial54FC0182651: [Errno 16] Resource busy: '/dev/tty.wchusbserial54FC0182651'

Just hooked up the vibration motor to M5Core and had the same problems as you had ... The vibration motor went up to > 1 Amp and the M5Core went into brownout ... I think the M5Stack Vibration Motor N20 uses the same schematic as the M5Stack N20 Propeller Unit ... ...i think the M5 Stack team screwed up with the resistors used for the control of the AO3400A mosfet : R2 as a pull down resistor should be 10k Ohm instead of 51k Ohm ! R1 as a current limiting resistor schould be 200 Ohm - 1K Ohm

Please post all the python code. errors don't always apply to a specific line and also don't count empty lines. IIRC (and there's a possibility I don't as it was last year) have you set up the digital twin and permissions on AWS for the code to connect?

You need to erase the Stamp S3 ore Atom S3 and install UIFlow2 Alpha firmware and then in M5Burner use config to view at the API code https://youtu.be/Pdo1ipf62VU

Hello, Anybody here to help me on this blocking point? Thank you Best regards

Hi everyone, I want to integrate this development board into M5Stack-Basic. Is it possible? In other words, M5Stack has devices that support voice recognition.
