ESP32: Unstable console

[opichals]

I have gotten the DOIT ESP32 board and have issues with basic espruino stuff like the following keyboard presses get corrupted on the way it seems (e.g. see the mangled process words below).

Any ideas?

$ npm run espruino

> d1-dht11@1.0.0 espruino /Users/standa/Dev/private/d1-dht11
> espruino -b 115200

Could also be related to other stuff I observe like https://github.com/espressif/arduino-esp32/issues/409 which sounds strange. Not sure.

First I have heard if anything like this. What power supply is used?

If characters are getting mangled, I'm surprised the flashing works.

Does it work from the web IDE?

[opichals]

I have it connected to a MacBook Pro USB port only. Will try the web IDE and write more later (had no such issues with the ESP8266 (d1 mini) on the exact same machine, using the espruino npm package though).

Thanks!

[opichals]

Same thing in the IDE.

No such issue with WeMos LoLin32 board observed

[wilberforce]

I think it is related to USB to serial chip used, and the driver for that chipset and the OS.

All of the boards seem to use a different chipset, so unless we document the board and the chip and OS, it will be hard to track. At least some patterns could be observed.

@opichals Want to leave this open? Do you think it was the board?

[opichals]

I tested MH-ET LIVE MiniKit for ESP32 and I didn't observe anything like this there.

I think it was a faulty board.
