uPyCraft no longer works on MacOS Monterrey.

It requires PyQt4 (which is no longer available) and QScintilla which doesn’t seem to work.

Trying to flash micropython to my ESP8266. Cleared the board using esptool.py erase_flash. Found my serial port as /dev/ttyUSB0. I then rshell to finish getting REPL. The program starts but then REPL searches and hangs. Is there something I am doing wrong? Ideas?

After flashing the ESP32, there is no boot file in ‘device’. No error shows at end of the flash, but no positive msg either.

Please help.

Thanks

I am unable to create a boot.py file. PC keeps asking me for a path to store the file.

Great tutorial. I was generally successful in installing micro Python on an ESP8266 and ESP32. I installed both IDEs on by WIN10 machine and both work well. uPyCraft IDE makes erasing and flashing the OS onto the microcontrollers easy.

Now down to my question:

In both IDES and on both controllers, %lsdevice returns an an error.

MicroPython v1.13 on 2020-09-11; ESP module with ESP8266

Type “help()” for more information.

%lsdevice
Unknown command: lsdevice

Help() works fine, so I know that I am ‘talking’ Thoughts? fixes?

One other thing that may or maynot be abnormal boot.py on both controllers contains only one comment line. Is that normal?

Is there a list of commands, like lsdevice?
