PIO unified debugger and sublimetext


#1

Hello,

I am unable to use the platformio unified debugger with sublime text…
I used the debugger feature with atom and vscode successfully.

I changed my IDE recently to sublime and I am unable to use the debugging feature.
Sublimegdb is installed.
I run the debug command and I get this error

irrespective of the different boards I try with…
I tried with 3-4 different stm32 discovery boards and I get the same issue every time.

These are the sublimegdb specific settings in the pio generated platformio.sublime-project.

   "settings":
    {
         "sublimegdb_workingdir": "/Users/srikrishnachaitanyanarumanchi/Documents/PlatformIO/Projects/disco_f030r8",
         "sublimegdb_exec_cmd": "-exec-continue",
         "sublimegdb_commandline": "/Users/srikrishnachaitanyanarumanchi/.platformio/penv/bin/platformio -f -c sublimetext debug --interface=gdb --interpreter=mi -x .pioinit"

    }

and this is the sublimegdb settings file

{
// All options in here can also be specified in your project settings
// with a prepended “sublimegdb_”. You probably want to
// have something like this in your project settings:
//
// “settings”:
// {
// “sublimegdb_workingdir”: “${folder:${project_path:your_executable_name}}”,
// // NOTE: You MUST provide --interpreter=mi for the plugin to work
// “sublimegdb_commandline”: “gdb --interpreter=mi ./your_executable_name”
//
// }
//
// generalized pattern for using always the current open file with an executable name
// as the current file
// “settings”:
// {
// “sublimegdb_workingdir”: “${folder:${file}}”,
// // put your arguments hear
// “sublimegdb_arguments”: “”,
// // NOTE: You MUST provide --interpreter=mi for the plugin to work
// “sublimegdb_commandline”: “gdb --interpreter=mi --args ./${file_base_name}”
//
//
// }
//
// If you want to debug different executables as part of the same project, you can add something
// like this to your project settings:
//
// “settings”:
// {
// “sublimegdb_executables”:
// {
// “first_executable_name”:
// {
// “workingdir”: “${folder:${project_path:first_executable_name}}”,
// “commandline”: “gdb --interpreter=mi ./first_executable”
// },
// “second_executable_name”:
// {
// “workingdir”: “${folder:${project_path:second_executable_name}}”,
// “commandline”: “gdb --interpreter=mi ./second_executable”
// }
// }
// }
//
// When you start debugging, you will be prompted to choose from one of your executables. Any
// settings not specified for that project will be searched in your project settings (with a
// sublimegdb_ prefix), then in your user settings, then in the default settings.
//
// (Note: if you have multiple executables, and you have a breakpoint set in a source file which
// is not included in the current executable, you may have to set either debug_ext or
// i_know_how_to_use_gdb_thank_you_very_much.)
//
// ${home}, ${project_path:}, ${folder:}, ${file} and ${file_base_name}
// tokens can be used in ‘workingdir’, ‘commandline’, ‘arguments’ options.
//
// ${home} is replaced with the value of the HOME environment variable.
//
// ${project_path:} tries to find a file with the given name in all the registered project folders and
// returns the first file found, or the original file name if none is found.
// Example: ${project_path:main.cpp} tries to find a file named “main.cpp” relative
// to the current project’s folders. If none is found, it is replaced with “main.cpp”.
//
// ${folder:} is replaced with the dirname of the given path.
// Example: ${folder:/path/to/file} is replaced with “/path/to”.
// “workingdir”: “/tmp”,
//
// ${file} is replaced with absolute path to currently open file (if any)
// Example: /home/user/main.cpp
//
// ${file_base_name} is replaced with name without extension of currently
// open file (if any)
// Example: replaced with “main” for file “/home/user/main.cpp”

Any ideas on what I am missing?? Did anyone else face this issue with sublime and pio??

Thanks in advance!! :slight_smile:

Ok…
never mind… It was a PEBKAC error… :stuck_out_tongue:

For anyone else who might run into the same issue.
The board in question is STM32F030 discovery.

You must add the extra commands as shown in
http://docs.platformio.org/en/latest/plus/debugging.html#st-util-and-st-link

These lines specifically.

debug_tool = custom
debug_port = :4242
debug_server = $PLATFORMIO_HOME_DIR/packages/tool-stlink/bin/st-util

Once I added those lines in the platformio.ini file, sublimegdb started working… :slight_smile:

Manually running the command in the sublime-project shone some light as to the possible cause what I did wrong…

In retrospect I realise, I gave absolutely no information about my project, board, platformio.ini files… :-I


#3

Does it work now? Can you do step debugging?


#4

Actually I spoke too early. The sublimegdb opened the debug session. However there was absolutely no indication that I was able to debug.

I tried with a simple Blinky for the target board and I never got the leds to blink.
I am at work now and have tried to debug with a stm32l100 discovery board.
I had to create a custom board for this, since the stm32l100 discovery is not in the present boards.

this is my disco_l100rct6.json file

{
“platform”: “ststm32”,
“build”: {
“core”: “stm32”,
“cpu”: “cortex-m3”,
“extra_flags”: “-DSTM32L100xC”,
“f_cpu”: “32000000L”,
“mcu”: “stm32l100rct6”
},
“debug”: {
“default_tools”: [
“stlink”
],
“onboard_tools”: [
“stlink”
],
“openocd_target”: “stm32l1”,
“svd_path”: “STM32L1xx.svd”
},
“frameworks”: [
“stm32cube”,
“mbed”
],
“name”: “ST 32L100DISCOVERY”,
“upload”: {
“maximum_ram_size”: 16384,
“maximum_size”: 262144,
“protocol”: “stlink”,
“protocols”: [
“stlink”,
“blackmagic”,
“mbed”
]
},
“url”: “https://www.st.com/en/evaluation-tools/32l100cdiscovery.html”,
“vendor”: “ST”
}

and this is my platformio.ini file.

The code compiles and I am able to flash it to the board. The leds blink as well…
But I am back to square one with the same error popping up when I try to debug.
I get the same pop up “You have not configured the plugin correctly…”

I am guessing I configured something wrong in th board.json file…

Manually running the same command as specified in the sublime-project file for debugging using platformio seems to be working . It is however flaky and seems to quit often. Further it seems to delete the watchpoints.

This is the entire log of the operations when run from command line.

It is programming well, and starting the debug server gdb.
It breaks at the temporary breakpoint where I set a breakpoint at main.c line 113.
and set a watch on the variable counter.
It seems to hang when I run after setting the breakpoints and watchpoints.

I am guessing this is what is happening even with the disco_f030 board I tried yesterday as well.


#6

changing the debug tool from stink to openocd gave this results.

platformio.ini file

openocd does not seem to be able to even start a debug session.

I ll try invoking the tools manually and report back in a while…

[Edit]
Manually running the openocd bundled with platformio gives this screen.

invoking the platformio bundled arm gdb. I am able to connect to the openocd instance using “target remote localhost:3333” and load the firmware elf file and single step it.

The leds light up and expected and I am able run the debugger.

A minor quirk I noticed is that the compiler seems to be optimising out the “counter” variable. I am unable to watch the variable. “Info variables” doesn’t show the variable counter. I did add the “volatile” keyword to the variable declaration to prevent the optimisation but the compiler seems to be still optimising it out.

This is the screen I get.

@ivankravets Hope this a little more informative on isolating the issue. :slight_smile:

(gdb) 

this is the console output when I run the debug command from command line.


#9

My bad… It debugs fine even when I manually invoke the pio debug command.
I gave “s” as the input instead of “step”. Using “step” command to manually step through works just fine.

“continue” or “c” works just fine. I misread the output.
Now I need to get the sublimegdb plugin work with this. instead of manually doing so from the command line.
:slight_smile:

[Edit:]
My mistake was that in assuming the command line for platformio debug would behave the same as gdb.
GDB executes the last command if only enter is pressed. pio debug does not do that.


#10

Further debugging shows this message in the sublime console.

Will write debug info to file: stdout
Running: notset
In directory: notset
error: You have not configured the plugin correctly, the default configuration file and your user configuration file will open in a new window

I am guessing that some settings in the sublime-project file generated by platformio are not setting correctly.
I ll investigate further and see if I can get it to run.


#11

Ok.
It seems to a very weird quirky bug.

I connected the board again, reinitialised the project again using the command line.
then opened the sublime-project file, did nothing except “save all” from the menu of ST3.

Then sublimegdb started working just fine.
Even single stepping and watching the variables.
Sublimegdb works as expected now. :slight_smile:

@ivankravets Thank you for the board definition. maybe this board too can be added to the list of supported boards.

I am leaving this post here if anyone else runs into the same issue later.


#12

Thanks! Added :wink:


#13

Just a follow up post for reference.

The process blew up in my face again when I tried to debug boards.
I carefully retraced my steps and I think I finally figured it out…

I ran the Pio init command from the command line and specified sublimetext as the ide …
It initialised just fine…
but sublimegdb won’t work unless you open the project in sublime and save the project explicitly.

i.e “Project > Save Project as > platform.sublime-project”

it might overwrite the platformio.sublime-project file but a quick undo will revert the changes.
Then and only then does sublimegdb work.


#14

Should we fix something here? https://github.com/platformio/platformio-core/blob/develop/platformio/ide/tpls/sublimetext/platformio.sublime-project.tpl

I see that we do automatic execution in wrong position. I’ve just fixed that https://github.com/platformio/platformio-core/commit/2ba41cddc45666ac3dd7c619ea19158898680061


#15

No Ivan,
The pio command did everything right. I m guessing it is a quirk with the sublime ide and/or sublimedebug package…

I didn’t have to do anything else except literally open the generated project and save it again to get sublimedebug work correctly.

Edit:
maybe this might explain why this is happening. When I generate a new project with “pio init” command, a new project is created. But I am unable to open the project in sublime. It just doesn’t do anything… I have to "Project > add folder to project > " and select the new project folder and then save it again…

Maybe the way that platformio is handling the sublime project creation isn’t entirely compatible??


#16

You need to double click on platformio.sublime-project file from project folder.

I’ve just tested and it works even with complicated FreeRTOS project based on ESP32. See below


#17

Yes, double clicking on the pio generated project file works perfectly…
Including sublimegdb and debugging…
As I have said earlier… PEBKAC error :stuck_out_tongue:

I literally didn’t have to do anything else… just double click on the sublime-project file and everything just magically works…

I m sorry, this entire thread has been a huge wild goose chase owing to my incompetence…
