Issues uploading to atmega324pb w/ adruino as ISP

Question

I've been having some issues programming a new atmega324pb I have on a custom board. I set up an old adruino UNO as an ISP by uploading the ArduinoISP sketch, setting the programmer to "Arduino as ISP" and then using the "Upload using programmer" option but to no avail. Here is the verbose error message that the console logs:

I think it might be an issue with Arduino possibly targeting a chip other than atmega324pb that I'm using, but I'm not sure. I don't know of any official arduino boards that utilize the 324pb. The main issue that I see is that avrdude can't find the device signature. I've see others mention it might be faulty wiring, but I made sure all connections are intact.

Answer 1

In case anyone was wondering, I solved the problem.
Unfortunately I wasn't able to figure out how to upload it using Arduino as ISP, but I was able to get it to work with an AVR Pocket Programmer from Sparkfun. If you decide to use this, check out this drivers guide. It will It'll save massive headache getting the usb device to be recognized.

IMPORTANT FOR ATMEGA324PB USERS!!!
The atmega324pb is apparently not a default microcontroller in avrdude. You need to add it to the toolchain manually. You can do this by following this blog:
https://hackaday.io/project/9313-uino-mini-super-atmega328pb/log/31003-easy-way-to-a-toolchain-for-the-atmega328pb
It is the same process to add any Microchip microcontroller to avrdude, so this guide will work for the atmega324pb (did it firsthand). From there, you can also add a custom entry to Arduino's boards.txt config file if you'd like to use the Arduino IDE for development. I didn't mind working the command line, but having it in Arduino definitely streamlines the proccess of compiling the .hex and uploading it in one go.

Here is the custom entry I added to Arduino's boards.txt file for the Atmega324pb. All the data was gathered from the datasheet:

####   ATmega324PB    ####
m324p.name=Atmega324pb
m324p.upload.via_ssh=true

m324p.vid.0=0x0424
m324p.pid.0=0x2740

m324p.upload.tool=avrdude
m324p.upload.protocol=usbtiny
m324p.upload.maximum_size=28672
m324p.upload.maximum_data_size=2560
m324p.upload.speed=57600
m324p.upload.disable_flushing=true
m324p.upload.use_1200bps_touch=true
m324p.upload.wait_for_upload_port=true

m324p.bootloader.tool=avrdude
m324p.bootloader.low_fuses=0x62
m324p.bootloader.high_fuses=0xD9
m324p.bootloader.extended_fuses=0x0f

m324p.build.mcu=atmega324pb
m324p.build.f_cpu=1000000L
m324p.build.vid=0x0424
m324p.build.pid=0x2740
m324p.build.usb_product="Arduino m324pb"
m324p.build.board=AVR_m324pb
m324p.build.core=arduino
m324p.build.variant=standard
m324p.build.extra_flags={build.usb_flags}

Note that I set the upload.tool to avrdude, and the upload.protocol to usbtiny since I was using the pocket AVR programmer.

IMPORTANT!!! The high fuse bit in this config also is 0xD9, instead of the default 0x99. I changed one fuse bit to disable JTAG and regain access to GPIO pins. To my knowledge Arduino wasn't setting fuse bits when uploading with the programmer, but this is an important note to take. If you need to use GPIO pins that share JTAG functionality, run the avrdude command line to set the high fuse bit appropriately. (0xD9 for me).
