Though this does work, I'm curious to know if you are working on a real fix via a firmware update.

sorry, this is caused by the battery voltage being too low(not booting for a long time). there is no way to solve it through the program,

So i have a dead on arivel M5stick C and my m5 fire does not support the usb modual i bought to add usable I/O.... not really loving this..

I just wanted to mention if you charge the m5stickc using a usb psu such as what you use to charge your phone it seems to charge the stickc battery and it turns on if you give it a few minutes. Not sure if this might be attributed to the usb output voltage on my computer not being stable but this always works for me. On the usb psu the voltage was 5.01v and on the laptop it was 5.22v so perhaps the overvoltage is an issue. I have 3 or 4 stickc devices and on a couple of them I always have to charge them first before they will boot.

Hi

Is there any news on this subject?

I've got 4 X M5stickC units, with 3 being "dead on arrival"

Plugging them into my laptop brings them to life, but only 1 stays on when the usb power is removed.

I loaded this example script to get the Battery & supply voltages

https://github.com/m5stack/M5StickC/blob/ce1af7500b9d2370983c778266e1ea941ac9f2d8/examples/Advanced/AXP192/PowerWake/PowerWake.ino

The good one shows about 4v from the battery and 4.99v on the usb power.

The other three show
Battery ~0.003v

I've tried the G0 to GND trick, but that didn't work.

I did go looking for a new firmware, as mentioned above, but the link is dead.

Any help would be most welcomed.

@mdar thanks for pointing to this script, I have the same issue : 0v on battery !

@zontex After a longer charging my M5stick works, but it is not possible to switch it into USB or WLAN mode, so I may upload code.
