I am trying to burn the bootloader on a blank Atmega328p-pu chip with an AVRISP MKii. But when I try to write the bootoader with the arduino IDE it gives the following error:
avrdude: Expected signature for ATMEGA328P is 1E 95 0F
Double check chip, or use -F to override this check.
Somtimes it gives the following error:
avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
this check.
I tried to read the signature of the chip in avrstudio and it there it says it matches with 1E 95 0F
Are all your connections correct? Do you have a crystal in the circuit? Are your wires making good contact? Is your reset wires connected properly? How do you have things connected? No one can help you unless you give us more details.
I pulled my good arduino chip out of the board and replaced it with a blank chip. And I used the icsp connecter on the arduino uno board to connect the programmer.
Does it say what the signature IS? Most likely cause: you have an ATmega328-PU chip instead of an ATmega328P-PU chip.
They're nearly identical, but the 328 has a signature ending in 0x14
If this is your problem, you can probably temporarily change the "uno.build.mcu" in boards.txt from "atmega328p" to just "atmega328" and burn the bootloader. Then change it back, because the bootloader will happily lie to the Arduino IDE and claim to be a 328p.
No it doesn't say what the signature is. It only gives the errors seen in the OP. I'm sure it is an Atmega328P-PU i checked it. I bought them because they were identical to the chip that came originally on the board.
I bought two atmega 328P-PU's but both don't work. But when I try to write the bootloader on the chip that came with the arduino it goes without a problem.
Can you run avrdude in verbose mode? Clicking the "burn bootloader" button while having compile/upload (in options vo 1.0) set to "verbose" should do it.
Usually if you can get as far as an "invalid signature", it means that a fair amount of the chip is actually working, but that's when using ArduinoISP, and the official programmer might behave differently.
Hi guys,
I'd been trying to burn my first bootloaders onto a couple of chips with my 'Uno' and was getting the same message. I was starting the wonder if the chips were dodgy, as I'd got them quite cheap on the net.
After an hour or two of googling, editing the boards.txt file, checking and rechecking the wiring, adding a capacitor etc... I exactly mirrored the breadboard setup on the other half of the breadboard to try my other chip without moving the first chip and it's wiring...I also pushed the chips more firmly into the breadboard and socket on the 'Uno' (they were originally not so tight to allow easy removal). The burn was successful, so I put chip #1 into the place of chip #2 and it burned successfully too.
I'm not sure what exactly made the difference, but the physical connections seem to be quite important.
In the end, it worked as per this instructable with no modifications:
As the knowledgeable lads above have said, check your connections are solid!
I made a pcb with atmega and got the same error message. I have to triple checked every pins of arduino atmega and problem solved. Check your crystal and capacitor also. Better to check connectivity directly from your target atmega to your AVRmakeII or the Arduino UNO.
Got it working. NOTE: Out of 5 chips, only one was labeled "328PB". The rest were 328P. The problem was only with the "328PB" The rest burned the bootloader find. BTW, I was burning the Nano Opti-bootloader.
My Hack was to edit the avrdude.conf file in the directory (on Win10)
search for m328, then commented out the first occurrence of "m328" and in the second occurrence of "m328" changed:
desc = "ATmega328PB";
to
desc = "ATmega328P";
Then Burn the bootloader to the Arduino.
Afterward, revert back to the original avrdude.conf file by removing the changes or if you made a backup of the original file(as you should've !!!) swop them.
So, my changes look like this:
--- Beginning of my Changes ------
#part parent "m328"
id = "m328p";
desc = "ATmega328P";
signature = 0x1e 0x95 0x0F;
ocdrev = 1;
#;
part parent "m328"
id = "m328pb";
desc = "ATmega328P";
add back the B after the 328P
signature = 0x1e 0x95 0x16;
ocdrev = 1;
;
end of Change
Note: After fiddling around some, my error changed. Adding the following for search purposes
The ATMega328PB is a different microcontroller, and so you'd expect to see errors when trying to burn a bootloader to it as if it were an ATMega328P. The easiest way to get it working is to use Minicore, which has support for the 328PB.
