Programming a standalone ATmega808-XUR using a Nano and UDPI

Using Arduino Microcontrollers
1

I'm attempting to upload a bare minimum sketch using Arduino's IDE to an ATmega808. I downloaded jtag2updi and uploaded it to a genuine Arduino nano board to convert it into a UPDI programmer. I then disabled the reset with a 10uF capacitor, connected D6 to the 808's UDPI pin via a 4.7kOhm resistor. The 808 is powered using the nano's 5V output.

Initially I figured the problem was my newly acquired SMD soldering "skills" but after purchasing an SSOP28 socket for troubleshooting, the problem hasn't gone away. Since this was my first time surface mounting chips, I had another 18 Atmel branded 808s on standby, but all of them returned the same error. In terms of software, I have already wiped and reinstalled Arduino IDE to my laptop, and did the same for all board hardware and libraries.

The issue I am running into is #402 and occurs with avrdude immediately after it establishes a system-wide configuration file. I've run the command just prior in the windows CMD, but nothing popped up with respect to missing .dll files. I've performed the exact same setup as countless others, with the only difference being the microcontroller I am using. The documentation for the 808 provided by microchip (assuming they're exactly the same as the Atmel ones) mentions High Voltage "HV" programming which I've never heard of before, but it doesn't seem to be required? I made sure that no bootloader was selected, and programming was done with JTAG2UDPI via the "Upload using Programmer" option.

Output:

I'm completely stumped as to why this isn't working. In the meantime, I have ordered a USB-to-TTL converter, and am learning PlatformIO since it has the 808 built in. Maybe that will fix my problem, maybe not? Perhaps trying another chipset might work?

2

Remove the manually installed MegaCoreX, restart the Arduino IDE and install MegaCoreX using the Boards manager installer. Instructions here:
https://github.com/MCUdude/MegaCoreX#boards-manager-installation

The latest version of MegaCoreX requires Avrdude 7.1 or newer, and the absolute easiest way to fix this is through a boards manager install.

3

That means you're not even getting to the point where avrdude tries to connect to the AVR, and all of your hardware-level debugging is ... pointless.

4

Thanks for the help! Pasting the github links in the additional boards manager and selecting "install now" is all it took. Not sure how I've come this far without realizing avrdude is a live project you have to occasionally update. Case closed!

Looks like I spoke too soon. I finally got avrdude to initialize the ATmega808, but I think the chip is locking me out? jtagmkII_program_enable() is returning a warning: RSP_ILLEGAL_MCU_STATE. I know one of the 808s locked states requires an AVR-HV programmer which I don't have so I really hope it isn't that. Maybe the serial number of 00:00:00:00:00:00 has something to do with it? This is happening with all the bare chips I have. Very strange, I could've sworn I was able to upload a bare minimum sketch a few days ago but now its giving me this. Any ideas?

The jtag2updi programmer may be unreliable at times. Build or buy yourself a SerialUPDI programmer instead. Less/simpler programmer hardware, faster, and better Avrdude integration.

Good idea. I've got the one you suggested on the way and in the meantime, I'll try building my own. Worst case I just have to wait for the dedicated one to arrive.
