Trying to program custom atmega320pb board with UNO and/or NANO

tuadru · July 17, 2023, 7:26am

Hello,
I am trying to program my custom atmega328pb board with both UNO and NANO as ISP programmers. I have uploaded ArduinoISP sketch to UNO (and later NANO) and then connected pins D13, 12, 11 and 10 (as well as 5V and gnd) to custom PCB ISCP header. Then I changed programmer to Arduino as ISP and tried burning bootloader but it gives me an error:

I have checked connections several times but not sure why it gives an error.
Any ideas what is going on?

b707 · July 17, 2023, 7:31am

atnega328p is not the same as atmega328pb. You should select a correct mcu to upload.

And then -

Signature with all zeros means connection problems. twice check your wirings.
Please draw the connection diagram and show in the forum.

b707 · July 17, 2023, 7:36am

BTW
if you are using a DIY board with an external resonator for clocking, it is very likely that your controller simply does not start. Try to apply an external clock signal with a frequency of 1-8 MHz to pin xtal1 and flash again

tuadru · July 17, 2023, 7:52am

As for custom board, basically I tried simulating UNO board so I have used external 16Mhz oscillator connected in parallel between xtal2 and xtal1 pins.
As for the board when trying to burn bootloader I selected UNO, should've I selected another one? So I need to try apply external clock signal somehow because it wont work otherwise? As for connection I triple checked them, on custom pcb I even checked if ISCP pins header is properly connected to atmega328pb pins and it is.

b707 · July 17, 2023, 8:00am

Indeed
You should selected exact atmega328pb.
The signatures of the chips are different, the avrdude program will not be able to flash the bootloader if you chose the usual atmega328p and try to flash the atmega328pb.

tuadru · July 17, 2023, 8:04am

In my boards I do not see atmega328pb as an option, it is only regular boards.
Should I maybe install or add something to be able to see that option?

b707 · July 17, 2023, 8:16am

There are some packages, supports the atmega328 "PB" variant. For example:

You also can try to call avrdude directly from command line.

tuadru · July 17, 2023, 8:19am

I have switched to NANO as programmer, installed boards you mentioned and selected atmega328pb Xplained mini, now I get this error which is different than one on UNO:

No, it is the same error. Signatures with zeros or 0xffffff has the same meaning - "no responce from the chip".

It is still a connection problem or chip doesn't start.

tuadru · July 17, 2023, 8:27am

Im 99.99% sure connection isnt an issue so I guess chip doesent start is the issue. Like I said Ive been copying UNO with custom PCB and I have connected external 16Mhz oscillator in parallel between xtal2 and xtal1 pins with all other components that go with it (capacitors and if I remember correctly resistor as well). How can I start the chip if it doesent start by itself at this point? You mentioned bringing external signal to xtal1 pin somehow?

Nano Atmega328pb
D13 -> SCK(pb5)
D12 -> MISO(pb4)
D11 -> MOSI(pb3)
D10 -> RST(pc6)
5V -> VCC(
GND -> GND(

b707 · July 17, 2023, 8:48am

Use a custom version of the ArduinoISP which adds an 8 MHZ 'crystal' output on pin #9 :

tuadru · July 17, 2023, 8:53am

So basically I upload this sketch to programmer and then connect d9 to xtal1 pin of atmega328pb and then burn bootloader? I will try that now.

TomGeorge · July 17, 2023, 8:56am

Hi,
Can you post a schematic of your project?

Can you post some EXPORTED jpg images of your PCB pattern?

Did you breadboard this project before going to PCB?

Thanks.. Tom..

As for the schematics I will upload shortly. I have tested functionality of the parts I want to control with UNO board and this custom pcb should simulate UNO board in sense it has necessary parts to work.

b707 · July 17, 2023, 9:20am

I used this sketch and it worked for me. Honesty, I did not download it from the github, but found it on the network.
If you do not find a solution before, I can post my version for you. But it will be in the evening, after 8pm (GMT +3) .

tuadru · July 17, 2023, 9:23am

Yeah you can do it as I can try with your sketch tomorrow then.
Here is pcb schematic:

You CAN NOT have MOSI connected to buzzer.
Remone R3 and try again

tuadru · July 17, 2023, 9:35am

Buzzer is not on pcb while I am uploading the code so there is an open line on the connectors where buzzer goes. But after I successfully upload the code isn't it possible to use pin as buzzer control? On UNO you can still use d11 even though it is mosi pin to connect external stuff on it?

b707 · July 17, 2023, 9:39am

If you use a SPI bus in the code - you can't use D11 and other spi pins for any purposes other than spi bus.
In other cases, this is the same pin as any other

tuadru · July 17, 2023, 9:41am

I am only using it to program the pcb, after that I dont use it anymore in the code. And it should not cause any problems while programming since the buzzer is not connected on the board currently so there is an open line after the R3 resistor, right?
