Terminal Gibberish?

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?

Don’t worry about that. This is because the boot baud rate is 74880. In WebIDE use 115200 to communicate with the esp8266.

those are boot rom messages that would be correct if device had 40Mhz external crystal fitted, with widely used 26MHz crystal the baud rate is not 115200 but 115200/40*26=74880

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?

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.
