M5 stick C wont turn on am i missing something?

iPodLux

Hi

It did happened to me few times on new Sticks, it looks like the issue sometimes is the testing runtime used before shipping.
Try this:
If it doesn’t turn on connect it to your computer,
launch the uiflow firmware utility,
you should see the serial port listed (the serial port chip is independent from power supply and should work),
erase content,
burn with fresh firmware
Repeat if necessary and make sure battery is charged

Apparently it is a common issue with the battery protection circuit (I have experienced this now!)

@cncninja sorry to hear your having issues with the stickC. As @iPodLux said, try reflashing it. First though if it doesn't show up in device manager on windows or system report on Mac then you probably have a dud and we should be able to replace it for you

if some firmware in stickc, please connect g0 to 3.3V, next insert usbC，it will work well

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 !

Hi @nicolas @MDAR if you guys still encounter this issue please contact me at roni@m5stack.com to resolve it, thank you!

@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.
