I charged my M5StickC to full and flashed a blinky sketch. It's been working just fine (including console log of the time) for hours now.
Have you tried charging yours fully?
It would be nice to get some bindings with the AXP192 though, as it also controls the backlight of the LCD :P It's using the st7735 but without the backlight getting power, we can't see anything on the screen (or at least that's what I think; maybe I'm just using the lcd wrong).
Would also be nice if we can somehow get something like https://www.espruino.com/Reference#l_NRF_getBattery working through the power management chip :P

I charged the M5StickC overnight and ran the AXP192 sample sketch throughout. When the voltage reached around 4v I flashed Espruino and ran the blinky sketch. When I first ran the AXP182 sample sketch, I saw that the battery voltage was just around 3v.
It looks like things are stable now, so maybe it could be because Espruino was trying to use too much power that the power management IC tried to restart the mcu?

I've just flashed the same binary to my m5 atom matrix https://docs.m5stack.com/#/en/core/atom_matrix which also has a pico-d4 but this one is stable and has been running the neopixel code https://www.espruino.com/WS2811#software for about 10 minutes now.
I'm not sure what the difference between the two are, except that one has a battery and the other doesn't. For what it's worth, here's the product link for the m5stickc: https://docs.m5stack.com/#/en/core/m5stickc

I might have just jinxed myself because now I'm getting all these problems too :D

Ahh, I think I may have just triggered it. It looks like since it's being displayed some time before I can connect via serial, I miss the message. I just saw the tip of the message that says SPI RAM enabled but initialization failed.

I'm not really sure, how do I find out? I just used the
scripts/provision.sh ESP32line for building.Looking at the script, it looks like this one:
curl -Ls https://github.com/espruino/EspruinoBuildTools/raw/master/esp32/deploy/esp-idf.tgz | tar xfz - --no-same-owner(commit message says it's 3.1.3)
-
I built it myself :)

Yeah, it runs the blinky the whole while (red LED is at pin 10 if you want to try it out).

The original manufacturer of the D1 mini https://docs.wemos.cc/en/latest/d1/d1_mini.html sells the D1 mini. They have a link to their own official aliexpress store.
I wonder though if you'd be better off getting an official board? I myself use the EPS8266 for some hobby work, but for actual installations I very much prefer the official boards (the Puck.js is especially nice). The nrf52 boards are also very power efficient and can run on coin cell batteries; I have yet to get an ESP8266 to lessen its power consumption.
There are also a number of other ESP8266 boards like the NodeMCU devkit but they're not as small. If you don't mind an ESP32 then the TTGo store in aliexpress also sells a number of custom chips that are already flashed with micropython (which usually means all the hardware necessary for flashing and using Espruino is already present). And of course there's the m5 stack line of products; the m5stickc is nice and small: https://github.com/m5stack/M5StickC
Thanks, I can confirm this does indeed activate the power management functions and allows the USB to charge the battery :)
