I'd like to know what went wrong

Development Tools Uploading
1

Hello,

Do you also hate the feeling when something went wrong, but you don't know what exactly happened? Here's the short story:

I uploaded the standard Blink.ino sketch on an ATMega328P using a breadboard and Arduino as ISP in Arduino IDE.
The led blinked very slowly, so I figured the chip was running on the factory clock setting of 8Mhz/8 = 1MHz. After that I tried uploading the bootloader. The process failed. Since then I can no longer communicate to the chip. (Yikes, invalid signature, check connections...)

Can anyone tell me if I did something wrong?

Also, the chip was given to me sitting on an old Arduino NG board, which doesn't use the 328P (as far as I know), that's why i tried it on a breadboard. Could the chip be damaged and did I just get lucky uploading the one program?

I'm clueless and I hate it :slight_smile:

The board is a VMA101 Atmega2560 mega development board.

Connections (328P --> 2560):

white - RESET (1) --> PIN 10
red - Vcc (7) --> Vcc on ICSP
black - GND (8) --> GND on ICSP
yellow - SCK (19) --> SCK on ICSP
brown - MISO (18) --> MISO on ICSP
green - MOSI (17) --> MOSI on ICSP

the ceramic cap is 100n (Vcc to GND)
the electrolytic cap is 4.7u (RESET to GND)

Arduino IDE v1.8.19 on linux with following settings:

Board: "Arduino Duemilanove or Diecimila"
Processor: "ATmega328P"
Port: "/dev/ttyACM0 (Arduino Mega or Mega 2560)"
Programmer: "Arduino as ISP"

When I "upload using programmer", avrdude says:

I also just ran this command in terminal (please, don't ask why :upside_down_face: ):

@er_name_not_found @groundFungus

Hi guys,
I really appreciate your interest.
I posted an update with additional info. I hope this can give you a clue on where to go next...

If I posted irrelevant info, please tell me what to remove.
If you need more info, tell me what to add.
If I shouldn't tag you, also let me know. I don't want to be annoying.

To make this somewhat concrete: let's try to upload that blinky again?
Preferably using the my current 'setup'.

Big thanks in advance!

5

This is not good, right? Should I bother hooking up and external clock or is this something you need an HVPP for to reset the fuses. Or should I not use these words and just wait for the pro's? I'm tier 0...

Also, I am reading this thread I try hardest to answer a post when and now I'm terrified :smiley:

6

Don't worry about that, it's for old salts to vent.

Your post is looking good so far.

You really want at least a minimum circuit for your 328:

You can program it while it's in this circuit too.

Hey, thanks for the input.
I'd have to desolder the crystal from the NG board I have to accomplish this circuit.
Would it be a good idea to put the chip back on the NG board and try programming through the icsp header instead of using a breadboard?
I was gonna try that last night, but I got tired and went to bed and honestly I forgot to try this today...
I'll try both and update...

Sounds like a good idea, but what is an NG board?

Some kind of old arduino board that used the atmega8 or atmega168, I can't find much about these myself and I don't know if many of these were made...
You can see the build-in led is not installed between GND and PIN13 but it has an internal 1k on PIN13.
When I put the chip in it blinked the led, before it went haywire...

10

Woah, careful with that thing, it's an antique.
I think that's meant for a 168.

I'd search "Uno Dip" on ebay and buy an Uno for that, or I'd buy the few components necessary to make the circuit I showed above.

If you desolder the clock, the pins might not be long enough to use with a breadboard.

11

That is a very good point you made there, and indeed, my brother told me to take care of this when he gave it to me a couple years ago.
I never got it working and just had it laying around until i started thinkering with an at85 recently.

This did the trick :smiley: and it blinks at the right speed now. Thanks for thinking along @er_name_not_found :pray:

Still don't know what went wrong, though...
But hey, I got a working chip now to figure that out.

Thanks again!

13

One more question:

How did you know a 16MHz clock would work? Because I think it ran on the internal clock when I first uploaded the sketch, it was running a lot slower on the same NG board.

14

You said it was a 328, check out the datasheet

That's a new one on me.
A more experienced used will be able to help, I'm sure.

When you burn an UNO/Nano bootloader it is going to set the chip fuses to use a crystal or resonator. If you don't have a crystal or resonator (you didn't) the processor clock won't run and you can't do serial programming (like Burn Bootloader or Upload Using Programmer). The target processor system clock has to be running and at least four times as fast as the programmer clock.

Once you put the chip in a board with a crystal the system clock was able to run and serial programming was again possible.

Another way around the problem is to inject an external clock to the XTL1 pin. Adafruit produced an "ArduinoISP" sketch that generated an 8 MHz clock on Pin 9 to allow programming of UNO/Nano chips without a crystal.

Thank you for the information @johnwasser!

So to conclude:
The bootloader did upload successfully. This switched the internal factory-set clock to an external clock that I needed to connect in order to program again.
