As mentioned I've 9 Gemma V2 boards currently trying to make at least one work.

Have downloaded the adafruit drivers - PC shows that USBtiny is connected. However the Arduino console says differently

#

Have tried with the latest version and then went hunting for 1.6.4 I believe it was. I was only successful hunting on github and found the 1.6.9 version.

#

all 9 of them give me this error code - they also do not hold red or blink, regardless of what I do.

#

I have reset them aka press down and again still no hold of the red LED

#

I've checked my settings

Sorry!

#

I'm just unsure where this would go/be hence the crossposting.

USB 3 ports will not work with this bootloader. It's a somewhat flaky bootloader.

#

Try a USB 2 port or try a USB 2 hub in between.

Thanks Danh, I'll hunt for my hub in the workshop and see if that works.

# carmine pilot Did you just buy these or you had them around? For future use, buy Gemma M0's if...

Oh gosh, I've had these since 2015. It's been many many years since I did any wearable things but my niece bless her soul, has asked me for a light up t-shirt she can wear whilst she undergoes chemotherapy.

So I've dragged out this old box in my workshop, I had great success many years ago with it but for some reason now yeah I have the issues.

The plan was to hook them up to some neopixel dots, and have a lipo battery pack for power. Something quick easy and simple as I have to also take a flight to the UK tomorrow to get to her hence the time issue 🫣.

she basically asked me this afternoon If I could do it. So I have to at least try!
