USBTinyISP kit from digikey

by cdan on Wed Sep 18, 2019 6:20 am

Hello,
FIRST: Are you using a USBtiny from a kit or from DIY?
Kit, bought from digikey
SECOND: What OS and computer are you using?
MacBook Pro MacOS Mojave and ubuntu linux
THIRD: Which programming software are you using, and what chip?
avrdude and Atmega168
FOURTH: Did the USBtinyISP ever work (even once) or is it your first time trying to talk to a chip
This is the first time.
FIFTH: Post screenshots (NOT copy&paste) of what is happening
Nothing is happening. The green LED is not on and the resonator is not oscillating. I have checked all connections and could not find any bridges etc. I can confirm that there is 5v between pin 10 and 20 of the attiny2313.
SIXTH: Post clear, in-focus, not-blurry, easy to see photos of the top and bottom of the kit. If the photos are blurry, unfocused, and difficult to see they will only make it harder to debug what is going on
See attachments.

Please advise on how to debug further. I do have an oscilloscope, any advice on how to check the resonator is welcomed.

Regards,
Dan

I have tried to connect it on all 4 USB ports and the result is the same.

DIgikey has sent me another microcontroller. I have swapped the old one with the new one and everything works as expected.

Problem solved.
