    Ok, explicitly changing the Web IDE baud rate to 115200 got the web ide working and I'm currently poking around how to access hardware, etc...

    Any ideas why I would be running into the other issues with CLI and local IDE?

    Both espruino -p /dev/tty.usbserial-0001 -b 115200 --ide and espruino -p /dev/cu.usbserial-0001 -b 115200 --ide still fail with Abort Trap: 6, even if I leave off the --ide option.

    Uploading a file fails as well in the same way.

    So using screen /dev/tty.usbserial-0001 115200 the terminal is unresponsive to any keystrokes.

    Using espruino -p /dev/tty.usbserial-0001 --ide I get

    Espruino Command-line Tool 0.1.40
    -----------------------------------
    
    Connecting to '/dev/tty.usbserial-0001'
    Abort trap: 6
    

    Using the web ide I get the attached images.

    Where do I go next?

    I'm getting a bunch of gibberish when connecting that seems to be blocking any actual usage. Wondering where I went wrong.

    I'm using a HiLetgo ESP8266 ESP-12E with my Macbook Pro M1. I am able to successfully run example sketches via Arduino IDE so I don't think it's a hardware issue.

    Here's the flash command and output:

    [~/Projects/rr-buttons/esp8266-firmware]­ $ esptool.py \

    But when I go to connect via screen I get gibberish before the Espruino prompt and the terminal becomes unresponsive to any keyboard input.

    The gibberish varies but I haven't figured out any way to decode it other than thinking "that looks a lot like control characters...":

    Any ideas what I screwed up?
