Hi I have used arduino for over a year updated to latest versions 2 and 1
Latest was making a ATTiny 85 programmer.
run the ISPArduino. had it working well
making a permanant one and couldn't upload ISP-Arduino to it, tried uploading Blink
and minimum sketch nothing.
I have tried 3 Nanos two, Unos and a Mega, tried a Nano on its own, nothing.
Went downstairs and tried on my laptop with IDE 1.8.19
still no joy. Help please Ive run out of options/ideas

Is there a common factor between your failed tests such as using the same USB lead and/or cable and/or PC ?
Can you change any or all of them ?
I have used one on Nano USB and a different one on the UNO
different PC
have used the same cable on the uno's will try another though
What exactly happens when you try to upload a sketch ?
Are the Arduinos recognised when you plug them into a USB port ?
Have you tried reinstalling or updating the IDE ?
it's always good to start with the basics
it the proper board selected under the Tools->Board:?
with the USB cable plugged into the board, does the Tools->Port show a different com port with and without the USB cable plugged in the PC/laptop? if so, is that the com port selected?
I have tied using different portsas suggested reinstalled the IDE 2, went back to version IDE 1-8-19 reinstalled 2..0.0 latest yesterday trying now on a laptop away from my desktop.
different usn different cables different IDEs the device manager recognises which port and tools port shows which current one I use a hub and unpluged from it to try USB on the desktop itself
OK, but -
What are you using?
- a windows 10 PC?
- a windows 11 PC?
- A Mac
- A linux PC?
- Web IDE?
Arduino IDE 2.0 is an early apha-state full of bugs.
(The arduino development Team claims something different but this is my opinion)
Can you flash something when using Arduino IDE 1.8.19?
I think Ive run out of options Thank you for responding so quickly as well
I even wondered if driver for USB was naff but that is showing the ports in device manager
when I upload sketches it reaches upload goes through 10 syncs cycles and shows error not syncing on both PCs
I'm on a windows 10 PC tried Ubuntu on desktop no joy, and now on windows 10 on a laptop
I use old version of programmer on Nano have changed to the other one in case
should have said old processor but tried the newer version
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x20
is the usual error I'm getting
Blockquote
I reverted back to IDE1-8-19 thinking the same as you, neither wants to know.
I cant even upload basic prog or blink even
get error avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x20
Did you try Tools>Processor>ATmega328P (Old Bootloader) ?
on both PCs
Thank you , yes I have tried all settings in programmer trying to upload
Do your boards have ch340s?
hi thank you yes ch340s I find the usb port I'm using comes up and also in device manager. I tried updating through windows update in case they had updated and mine was not functioning but all seemsOK on that score

Hi. I found a solution to this , I had several goes and after a bit burnt bootloaders and some of my Nano's responded and are back in use.
That didn't work on all, so I tried to upload over USBasp and that sorts out the last ones that wont work .
I agree IDE-2.0.0 does seem to still have some glitches and takes me some messing about and hours to get where I want to be.
Thanks for your time and help.
Bob
