Atmega328pb Xplained upload problems

oceansource · October 24, 2020, 9:29pm

Hello, I found an Atmega328p Xplained board while cleaning out a closet and wanted to mess around with it on Platform IO.

I’ve spent some time reading some forum posts about uploading to it, but I’m not having any luck. I’m pretty sure I don’t have the atmel studio driver problem, but I’ve tried reinstalling drivers to libusb32 and libusbk (didn’t work). I keep getting the same error:

*** [upload] Error

Here is my platformio.ini with a few options I have commented out, none of the upload protocols are working for me:

[env:ATmega328PB]
platform = atmelavr
board = ATmega328PB
framework = arduino
upload_protocol = xplainedmini
;upload_protocol = xplainedmini_dw
;upload_protocol = xplainedpro
;upload_flags = -P usb

When changing the drivers didn’t work I let windows locate and install the “best drivers”:

Any help would be apreciated!

This command still contains the auto-detected COM22 port which avrdude doesn’t seem to like. Please try the following:

In VScode, open a PIO terminal. Then try each of the commands until one one works or throws some other error:

C:\Users\email\.platformio\packages\tool-avrdude\avrdude.exe -v -p atmega328pb -C C:\Users\email\.platformio\packages\tool-avrdude\avrdude.conf -c xplainedmini -b 115200 -D -Pusb -U flash:w:.pio\build\ATmega328PB\firmware.hex:i

I also note that -e (erase) is not contained in any flags – so if some other partial verification shows up, try adding -e at the end.

Hopefully that revelas what the correct upload command is and if the -P "COM22" is the problem here.

@maxgerhardt Port 22 is the CDC virtual com port (interface 1). It looks like PIO automatically wants to use that port to upload.

Here are the results of the commands.

With these drivers:
mEDBG CSMIS-DAP (Interface 0): WinUSB (v6.1.7600.16385)
mEDBG CDC (Interface 1): usbser (v7.3.0.0)

Every command gives me this response:

avrdude.exe: jtag3_open_common(): Did not find any device matching VID 0x03eb and PID list: 0x2145

avrdude.exe done.  Thank you.

If I switch to libusb-win32 drivers (unplug and plug back in after driver switches):
mEDBG CSMIS-DAP (Interface 0): libusb0 (v1.2.6.0)
mEDBG CDC (Interface 1): libusb0 (v1.2.6.0)

I lose the ability to communicate with the CDC virtual com port (port 22) that you believe was causing the problem when I attempt to upload using the platform IO button. When I attempt to upload using the PIO upload button, PIO tries to upload to COM 8 which is one of my RS232 adapters. So… Since COM 22 goes away when I use libusb drivers on the CDC interface 1 device, PIO just grabs the next available com port?

So I reinstall the windows driver for that interface (right click in device manager and “update driver”) and now my drivers are listed in Zadig as:
mEDBG CSMIS-DAP (Interface 0): libusb0 (v1.2.6.0)
mEDBG CDC (Interface 1): usbser (v7.3.0.0)

Which allows me to communicate with the CDC interface via a terminal.

I just want to stress that I needed to unplug the board and plug it back in after updating my drivers, if you don’t you get errors and freezes.

Doh! My board is a 328p Xplained Mini, not the 328pb. I edit that argument in the command.

And like you mentioned, It looks like I need the erase argument, so I add the -e to the end of the command.

This successfully runs my program that blinks the LED and prints hello world to port 22.

Just to check I ran the other commands you suggested, and here are the results:

It looks like it works fine without the -Pusb argument.

Thanks a lot for the help so far. Any suggestions on correcting the PIO update behavior and getting debugging working?

maxgerhardt · October 25, 2020, 4:23pm

Could you try this platformio.ini

[env:ATmega328P]
platform = atmelavr
board = ATmega328P
framework = arduino
upload_protocol = custom
upload_flags =
    -C
    $PROJECT_PACKAGES_DIR/tool-avrdude/avrdude.conf
    -p
    atmega328p
    -Pusb
    -c
    xplainedmini
    -e
upload_command = avrdude $UPLOAD_FLAGS -U flash:w:$SOURCE:i

This should correct the used board and straight up inject the correct upload command instead of attempting to fix that PlatformIO injects -P"COM22" in the commands (didn’t have a play but maybe modifying upload_port = usb or something works too?)

If it can’t find avrdude then please replace the last line with

upload_command = $PROJECT_PACKAGES_DIR\tool-avrdude\avrdude.exe $UPLOAD_FLAGS -U flash:w:$SOURCE:i

oceansource · October 25, 2020, 4:51pm

That works for uploads.

Attempting to debug gives me this:

Error: Currently, PlatformIO does not support debugging for `ATmega328P/PA`.
Please request support at https://github.com/platformio/platformio-core/issues
or visit -> https://docs.platformio.org/page/plus/debugging.html
The terminal process "C:\Users\email\.platformio\penv\Scripts\platformio.exe 'debug'" terminated with exit code: 1.

Terminal will be reused by tasks, press any key to close it.

I am just messing around with this board, if you don’t feel like figuring out the debugging I won’t take it personally. I see in the documentation a fuse might need to be set:

http://ww1.microchip.com/downloads/en/devicedoc/50002659a.pdf#page=8

I know the board has an ATmega32U4 that is used to debug / upload. I don’t know much about different debugging protocols or basically anything beyond pressing debug on an IDE/

maxgerhardt · October 25, 2020, 6:15pm

Indeed, PlatformIO has no native support for debugging real AVR hardware. Only simavr as a simulator. You might want to see if avarice can connect to the chip and open a GDB server, as in Atmega32 debugging with avarice and avr-gdb - #2 by mate910327. This is all relatively unchartered territory though.

oceansource · October 26, 2020, 11:14am

Thanks for the help Max.

The avarice / GDB stuff looks fun to learn about. While I was reading about GDB I came across this github issue Support for other development tools · Issue #11 · jdolinay/avr_debug · GitHub which is discussing the code in these two repos GitHub - jdolinay/avr_debug: Source level debugger for Arduino - GDB stub for Atmega328 microcontroller used in Arduino Uno. and GitHub - msquirogac/avr-debugger-bootloader: avr-debugger bootloader to enable Flash breakpoints, built throught PlatformIO.

Which also looks fun.

Just wanted to mention it for anyone that might land on this post and wanted to try it out.

Thanks again!

maxgerhardt · October 29, 2020, 7:34pm

The avr-debug project with its GDB stub are now officially supported in PlatformIO! Atmel AVR dev/platform v3.0.0: updated Arduino cores, support for AVR GDB stub

That’s awesome!

This program / community is the best.
