it’s hard to say… before I had discovered the oddity with one of my chip, I would have said the clock/crystal would be the culprit - now I’m not sure though it is the most likely.
how are you uploading the script? what are the fuse settings reported by:
sudo avrdude -c linuxgpio -p atmega328p -v
… on a sidenote I’m using avrdude 6.1, as shipped with Raspbian at this stage, but I can’t imagine that being significant.
er, just noticed in your Fritzing diagram, cathode of LED goes to 3v3 rail on bredboard. It should go to ground right?
yes I edited the post saying that it goes to ground in real life
I am uploading like this.
make && sudo avrdude -c linuxgpio -p atmega328p -v
and the output from
sudo avrdude -c linuxgpio -p atmega328p -v
is

avrdude done. Thank you.
you are not specifying a file to upload in your first command. I did notice that the default at my end was named Blinkt.hex btw, rather than blink.hex so you’d need to run something like:
make && sudo avrdude -c linuxgpio -p atmega328p -v -U flash:w:build-uno/Blink.hex:i
if that still does not work, try with enforcing the part and clock in the Makefile:
MCU = atmega328p
F_CPU=16000000L
include /usr/share/arduino/Arduino.mk
Added the lines to the makefile and nothing changed I am starting to think that a broke something whilst soldering. If I get round to it I should be ordering some stuff at easter so I will chuck in the stuff I will need for another go at it.
Just an idea couldn’t this make quite a neat phat I think it could become quite popular and might actually work if you put some caps on it!
Oh yes that is well established solution. Completely forgot about it!
