I’m trying to get debugging on the UNO working using the avr-debugger. (Linux desktop)
I’ve installed the library, and as per the documentation I’ve added the
#include “avr8-stub.h”
#include “app_api.h”
includes as well as the debug_init(); in the setup.
I’ve also set my platformio.ini to have the extra variables
debug_tool = avr-stub
debug_port = /dev/ttyUSB1
lib_deps = jdolinay/avr-debugger@^1.5
When I compile it says that it can’t open the include files. What am I missing?
Full platformio.ini please.
Did you already refresh your intellisense by doing Ctrl+Shift+P → Rebuild Intellisense Index?
Thanks for replying. My platformio.ini is as follows:
[env:uno]
platform = atmelavr
board = uno
framework = arduino
monitor_speed = 115200
debug_tool = avr-stub
debug_port = /dev/ttyUSB1
lib_deps = jdolinay/avr-debugger@^1.5
I’ve found that adding
#include <app_api.h>
to main.cpp seems to find the other include files, so now onto the next error:
* The terminal process "platformio 'debug'" terminated with exit code: 1.
* Terminal will be reused by tasks, press any key to close it.
* Executing task in folder blinkpin: platformio debug
Processing uno (platform: atmelavr; board: uno; framework: arduino)

============================================================
An unexpected error occurred. Further steps:
* Verify that you have the latest version of PlatformIO using
`pip install -U platformio` command
* Try to find answer in FAQ Troubleshooting section
https://docs.platformio.org/page/faq/index.html
* Report this problem to the developers
https://github.com/platformio/platformio-core/issues
============================================================
* The terminal process "platformio 'debug'" terminated with exit code: 1.
* Terminal will be reused by tasks, press any key to close it.
That usually appears if you have an invalid lib_deps expression in your platformio.ini.
Can you take a screenshot of VSCode with the platformio.ini open and post it here?
That should not happen.
Can you, in the terminal in VSCode, execute
rm -rf .pio
rm -rf ~/.platformio/lib
to make sure there aren’t any zombie libraries causing this issue.
So it rebuilt the libraries but failed on linking.

You cannot use the Serial object in your code because the serial is used by avr-stub to exactly communicate with the GDB client. Please exactly use the example code in
https://docs.platformio.org/en/latest/plus/debug-tools/avr-stub.html
as your first test program and double-read the documented limitations section.
Ah, that explains it. Thanks for your time.
