Debugger not starting

Advanced Solutions Debugging
1

Hello, I’m trying to get debugging working for a nRF52 based board, but when I start the debugger via the PIO Debug option from the dropdown it just compiles the firmware and doesn’t do anything afterwards (it only shows an infinite loading bar in the debug/run side panel).

My platformio.ini is this:

[env:rak8211_nb]
platform = nordicnrf52
board = nrf52_dk
framework = zephyr
board_build.mcu = nrf52832

upload_protocol = custom
upload_command = $PROJECT_PACKAGES_DIR/tool-openocd/bin/openocd -f $PROJECT_PACKAGES_DIR/tool-openocd/scripts/board/nordic_nrf52_ftx232.cfg -c init -c "reset init" -c halt -c "program {$SOURCE} verify" -c reset -c exit
debug_tool = custom
debug_server = $PROJECT_PACKAGES_DIR/tool-openocd/bin/openocd -d -f $PROJECT_PACKAGES_DIR/tool-openocd/scripts/board/nordic_nrf52_ftx232.cfg

I’m using a FTDI FT2232HL based board to connect to a RAKwireless RAK8211-NB and uploading the firmware works just fine.

Am I missing something to get the openocd gdb server running and connected? According to the Debug Console tab it never runs my custom openocd commands.

I’ve noticed that sometimes it takes quite a whole for the openOCD invocation to happen. Have you waited for like, 5 minutes?

The docs only describe the style that separates each argument in its new line… Well if upload_command works like that, then I guess it works like that, too

What’s the output when manually run

$PROJECT_PACKAGES_DIR/tool-openocd/bin/openocd -d -f $PROJECT_PACKAGES_DIR/tool-openocd/scripts/board/nordic_nrf52_ftx232.cfg

in a command terminal (with adapted paths)?

Also I’d suggest to explicitly add

debug_port = localhost:3333

to the platformio.ini since that’s where openOCD should start the gdb server.

I just tried waiting for ~15 minutes but nothing happened (and it didn’t seem like it was doing anything in the background according to the CPU usage). Is there any reason it would wait before executing the debug_server command?

I tried that first but at least for the upload command it only used the first line and not all of them for some reason, so I just went with all in one line…

When I run the command directly it starts as expected on port 3333, just like you said:

It just seems like it doesn’t even try (or silently fails) to execute the command. Is there maybe anything I have to change in the VSCode launch.json file? (afaik that file is autogenerated though)

Hm I had the idea of running debugging in the commandline to see more output but that doesn’t look good either (Debugging not accessible on commandline using Windows CMD · Issue #3793 · platformio/platformio-core · GitHub)

The thing is there should be some output, even if it’s failing. I’m e.g. testing with a STM32 Bluepill config but no connected STLink, and launching debugging gives

And on the commandline output

All that good debug output.

Is there also no output with the “skip Pre-Debug” Debugging option?

And then click on that play button.

With the skip Pre-Debug option it looks the same:

Even when I disconnect the board there are no errors…

I noticed that the project name is missing after the name of those options, does that mean anything?

It should not, I just have multiple projects in my workspace, thus the needed distinction.

One obversation I just had was that when just using the platformio.ini

[env:rak8211_nb]
platform = nordicnrf52
board = nrf52_dk
framework = zephyr
board_build.mcu = nrf52832

upload_protocol = custom
upload_command = $PROJECT_PACKAGES_DIR/tool-openocd/bin/openocd -f $PROJECT_PACKAGES_DIR/tool-openocd/scripts/board/nordic_nrf52_ftx232.cfg -c init -c "reset init" -c halt -c "program {$SOURCE} verify" -c reset -c exit

(to get the default JLink debug method) and starting PIO debug, I did get some output, after being away from the computer for… half an hour? Don’t quite remember.

Obviously something is wrong there…

I’ve opened issue Debugging not started or takes ages · Issue #102 · platformio/platform-nordicnrf52 · GitHub since I’m out of ideas.
