hi John

I'm glad you downloaded this right away.
@kittaakos is looking into this, we must have added some regression in the communication between UI and CLI.

As I was telling you a couple days back the debugger didn't get much love this time around, as we had to focus on releasing a more stable editor with broader compatibility, but it's definitely on our list for the next few weeks.
At least now you have access to nightly builds, so if it's something we figure out quickly you'll be able to get a working version faster than 4 months from now :D
I'll make sure this issue gets updated as we know more.

Thank you :)

jwestmoreland · 2020-08-25T07:28:52Z

Hello @ubidefeo ,

Yes, not much love appears to be no love at all actually; ;) - hope this can move forward but there's more ways to debug as we've discussed as well.

That's cool we have access to nightly builds now - thanks for letting us know about that!

And, thanks for looking at the debugger issues as well.

You are more than welcome!

Best Regards,
John W.

kittaakos · 2020-08-25T08:54:30Z

I have a quick update: we have identified the breaking change. I built a CLI with a tiny modification locally, dropped it into the IDE and the debugger works.

jwestmoreland · 2020-08-25T08:58:41Z

Hello @kittaakos ,

So, will this be in the nightly update or how can I give it a try?

Thanks,
John W.

kittaakos · 2020-08-25T09:02:48Z

will this be in the nightly

Yes, once we fix the issue and very it, we will make it available in the nightly.

how can I give it a try?

I will keep you posted. Thank you for logging the bug.

jwestmoreland · 2020-08-25T09:05:49Z

Hello @kittaakos ,

Thanks for getting to this so quickly!

And, sure, NP - been waiting for the ThreadLib stuff to get stable.

Thanks Again,
John W.

ubidefeo · 2020-08-26T12:39:21Z

@jwestmoreland
you could try the nightly but we're also doing a patch release possibly today

kittaakos · 2020-08-26T12:49:13Z

you could try the nightly

Please note, the nightly won't work until we have another CLI release.

kittaakos · 2020-08-26T14:59:55Z

@jwestmoreland, we have a new IDE release with the debugger fix: https://github.com/arduino/arduino-pro-ide/releases/tag/0.1.1

jwestmoreland · 2020-08-27T06:04:00Z

Hello @kittaakos ,

OK - thanks for that - and loaded it - just wondering, has anyone debugged anything with it?

I got this when I tried to debug:

kittaakos · 2020-08-27T07:16:34Z

has anyone debugged anything with it?

Of course.

On Windows and macOS, we verified the basic debugging features on a compiled sketch,

such as start debugging,
hit breakpoint,
step in/out,
change local variables (int),
stop/restart the debug session.

On both Windows and macOS, we used an Arduino Zero board, plus we tried it with CMSIS-DAP debugger on Windows.

Reading symbols from c:/tmp/demo-web-server/build/arduinobeta.mbed.envie_m7/demo-web-server.ino.elf...
done.

I do not know if debugging works with the Portenta board. @ubidefeo, can you please help with this?

jwestmoreland · 2020-08-27T07:22:44Z

Hello @kittaakos ,

Thanks for the response.

Since this is the arduino-pro-ide 'forum' - thought Portenta as the target was/is implied.

Thanks,
John W.

pnaybour · 2020-08-27T09:22:55Z

@jwestmoreland i am not to sure about the support for Portenta board.

jwestmoreland · 2020-08-27T09:27:19Z

Hello @pnaybour ,

TheadLib is in the Portenta library source files - so, why would that be the case?

Thanks,
John W.

ubidefeo · 2020-08-28T16:19:31Z

@jwestmoreland
as I was pointing out the other day this release was largely focusing on getting a more stable and usable IDE out the door.
Now we have the platform (nightly builds are a huge part of this new workflow) to accept requests for change and show that we work on features.
Portenta is a big part of this transition, and we're actively investigating its behaviour with CLI and Pro IDE as well as looking into how to offer a working debugger that people actually want and can use

You and other users will be able to see things moving at a faster pace, so please keep on submitting your issues and telling us what doesn't work so we can make a plan to fix it :)

jwestmoreland · 2020-08-28T23:28:31Z

Hello @ubidefeo ,

Absolutely, as evidenced here.

I hope the nightly builds will have a log as to which bugs could have been fixed or at least are ready to test to see if they've been fixed - by issue number.

Thanks!
John W.

ubidefeo · 2020-08-29T07:42:58Z

@jwestmoreland
nightly builds at the moment do not come with a commit history, but let's look into how we can automate that.
@silvanocerza @kittaakos this one is for you, I guess ⬆️

On Monday I'll check with @facchinm what's left to do to enable debugging via ThreadDebug on Portenta, we already chatted about it a few days ago but need to collect more info to make into a clear development/fix task. I'll notify you as soon as we have something.

Thank you again for being (or trying to be) so active with Portenta and the new IDE, hope it doesn't cause too much frustration as you bring valuable feedback to this project :)

jwestmoreland · 2020-08-29T08:17:38Z

Hello @ubidefeo ,

OK - yes, I think a commit history will be really helpful in this stage of things - thanks for that.

Seems like ThreadDebug is really close to being functional and that will be extremely helpful. I also have a thread here: that's the original post I had regarding ThreadLib.

Thanks for discussing with Martino, and sure, I think we all will benefit once this is solid - I really enjoy embedded systems.

Best Regards,
John W.

kittaakos · 2020-09-03T07:39:54Z

I hope the nightly builds will have a log

It's available. Please reference the updated documentation here. Here is the direct link to the changelog.

jwestmoreland · 2020-09-03T07:55:10Z

Hello Akos,

Thanks for doing this. Much appreciated.

Regards,
John

kittaakos · 2020-09-11T09:50:10Z

To sum up:

As I wrote here, IDE2 does not do more than calling the debugger.

From the command line - using what was compiled by the 0.1.0 IDE - it does run:

C:\tmp\demo-web-server\build\arduinobeta.mbed.envie_m7>C:\Users\John\AppData\Local\Arduino15\packages\arduino\tools\arm-none-eabi-gcc\7-2017q4\bin\arm-none-eabi-gdb -ex "set pagination off" --baud 230400 -ex "set target-charset ASCII" -ex "set print pretty on" -ex "set remotelogfile mri.log" -ex "target remote COM4" demo-web-server.ino.elf

@jwestmoreland, I do not know how did you end up with that command, something else is defined in the platform.txt of the core, but after adjusting the command that worked for you to my macOS env, I got no output:

 % /Users/akos.kitta/Library/Arduino15/packages/arduino/tools/arm-none-eabi-gcc/7-2017q4/bin//arm-none-eabi-gdb -ex "set pagination off" --baud 230400 -ex "set target-charset ASCII" -ex "set print pretty on" -ex "set remotelogfile mri.log" -ex "target remote /dev/cu.usbmodem14601" /Users/akos.kitta/Documents/Arduino/Blink/build/arduino-beta.mbed.envie_m7/Blink.ino.elf

There was another probably important comment here that I do not understand:

OK - I changed COM11 to COM2 and it appears to have fixed that...on the CLI...

Where did you get this info from? Can you please help, @jwestmoreland? Once I can run gdb from a terminal using the CLI, I can make it work with IDE2. Thank you!

jwestmoreland · 2021-02-24T22:32:41Z

@kittaakos ,

Can you let me know what's unclear now - I'm wondering what the actual question(s) is/are that you want me to answer?

Thanks,
John W.

ubidefeo · 2021-02-26T21:25:38Z

hi @jwestmoreland
This is a fairly old thread.
We have since assessed that changes are to be made to the arduino:mbed core in order to get the ThreadDebug port to be recognised and used at the start of a debug session.

The issue will remain open until we have this implemented and working :)
