I bought some new atmega328p chips from DigiKey, no boot loader. I tried burning the boot loader w/ a Genuine UNO and a ZIF hat. Got the "Expected signature for ATmega328P is 1E 95 0F Double check chip, or use -F to override this check.". This set up works for older 328 chips, but not the new 328p. Where can I get a boot burner that works on new 328p chips?
Hi @jeff51. I'm going to ask you to provide the full verbose output from a "Burn Bootloader" operation.
This procedure is not intended to solve the problem. The purpose is to gather more information.
Please do this:
- Select File > Preferences... (or Arduino IDE > Settings... for macOS users) from the Arduino IDE menus.
The "Preferences" dialog will open. - Check the box next to Show verbose output during: ☐ upload in the "Preferences" dialog.
ⓘ This preference applies to "Burn Bootloader" operations in addition to uploads. - Click the "OK" button.
The "Preferences" dialog will close. - Attempt a "Burn Bootloader" operation, just the same as you did before.
- Wait for the "Burn Bootloader" operation to fail.
- You will see a "Error while burning the bootloader: ..." notification at the bottom right corner of the Arduino IDE window. Click the "COPY ERROR MESSAGES" button in that notification.
- Open a reply here on this forum topic by clicking the "Reply" button.
- Click the
<CODE/>icon on the post composer toolbar.
This will add the forum's code block markup (```) to your reply to make sure the error messages are correctly formatted.
- Press the Ctrl+V keyboard shortcut (Command+V for macOS users).
This will paste the error output from the upload into the code block. - Move the cursor outside of the code block markup before you add any additional text to your reply.
- Click the "Reply" button to publish the post.
Take a few minutes to look at Nick Gammons' article on burning bootloaders.
I Googled gammon.au burn bootloader.
It's a bit old now, but gives a good insight.
Is that a 328P, or a 328PB - it matters!

Seems this is a case of its not a P type given its marked PU and Looking around on the web I found this mentiond a few times ;
" base model ATMega328 (no suffix) and the ATMega328PU, both of which yield a 0x1e9514 signature instead of the expected 0x1E950F "
You have the ATmega328, not the ATmega328P (the pico power version). You wanted
You can still use the ICs you have. Use the MiniCore coreplatform, and choose the "328 / 328A" variant of "ATmega328".
