Bootloader problem

Using Arduino Microcontrollers
1

Gday',

Apologies if I have picked the wrong thread.

Problem : I cant burn my bootloader (but I have done so in the past)

I've tried a few things
1: I made up a programming shield (that I've used before) and wacked in my chip to be bootloaded. and it failed. Perhaps I busted that crystal (I did just throw it in my tool box). I replaced the crystal. still no go.

So then I'm thinking perhaps my uno programmer is busted.

2 brandspankers arduino UNO's spi out -> pin 10,11,12,13 you know the drill.
still no go.

So now I'm thinking I've purchased some dud 328p-pu blanks!

I even ran up avrstudio with my stk500 programmer.
The funny thing is that with the stk500 programmer it gives no error message.
But when I take my 'new' chip and put it in an arduino I cant run up a blinkie.

So I have 3 questions.

1 - I'm running windows 10 - is anyone having issues with this os? perhaps the ftdi driver thing is back atm?
2 - I've ebayed the 'blank' 328p-pu. I've never purchased doa chips. Has anyone else?
3 - The chips labled atmel328p-pu <- are they all the same. (I would expect so)

I'm thinking I've purchased 5 dud chips.

Thanks in advance!

Suggestions
Try Nick Gammon's board programmer sketch. Google "gammon bootloader".

Insert the new chip in a known good Uno.

Do the loopback test (see pinned threads of the Installation and Troubleshooting forum).

In the IDE preferences checkmark show verbose output on upload.

If you continue to have trouble, it will be time for you to give extreme details about what you are doing. Be exact, step by step, include all selections you are making on the menus, leave no detail out, pretend we don't know the drill, show diagram of your wiring (hand drawn schematic is best), and photos showing neat wiring clearly. What you want is to give enough detail that we may be able to see what you are missing.

You have more than one UNO I suppose? First make sure an UNO works with blink. Then remove its 328P. Try to bootload it with your setup see if it bootload or not. If it does but yoru 5 ebay 328Ps don't, you know you've been fooled.

Also, enable verbose upload output and post the output here.
