M4SK: Wont turn on

by jakel on Sat Oct 03, 2020 7:37 pm

I have a brand new M4SK (came with adabox 13) that won't turn on:

- When I plug it in to usb for power, the chg (charge) led blinks once briefly (does not matter if the unit is off or on), the screens do not turn on, no other led activates.
- If I switch from off to on it blinks briefly again but screens do not turn on.
- With the battery attached the chg led remains on
- After charging the battery for about an hour if I remove usb power and toggle the power on or off nothing happens

Is there something wrong with the board or am I just missing something?

Thank You!

Hi jakel,

It sounds like the power switch in the top right position might be in the off position. Please take a look:

Thank you for your response. I don’t believe that is the problem as I have toggled the off and on switch. That has no effect.

@jakel,

When the M4SK is plugged into your computer via USB DATA cable are you able to see a USB drive? If you double click the 'reset' button does a drive come up? I'd like to have you upload the UF2 bootloader if possible.

@mikeysklar

I tried a few cables. The board was not recognized by my computer. I don’t know how to tell the difference between data and non data cables. I did use a kindle cable which works fine for my kindle data but did not work with my MS4K. Thank you.

The easiest way to tell if a cable is DATA is to do the test you have done. If it works with your Kindle for syncing then it is a DATA cable.

Any response from double pressing the 'reset' unit when plugged into USB? This should put you into bootloader mode.

Do you see a drive mount or any LEDs illuminate?

@mikeysklar

I tried the reset button single click, double click, along with frustrated random clicking to no avail. It never registers as a drive on my computer while using a data cable.

- When I plug it in to usb for power, the chg (charge) led blinks once briefly (does not matter if the unit is off or on), the screens do not turn on, no other led activates.
- If I switch from off to on it blinks briefly again but screens do not turn on.

@jakel,

Let's get you a replacement. This behavior sounds more like a hardware / firmware issue than anything else. Since we cannot get a fresh bootloader on their in it's current state we can move on.

Please send an e-mail to support@adafruit.com requesting a replacement M4SK. Provide them with your order# and this forum thread link.
