How to configure DDS and DevTools for special target device #251

nguyenlkdn · 2024-04-04T05:49:09Z

When attempting to connect to the VM service URI output by the Flutter engine in the context of a custom embedder, users may encounter the following error:

This VM does not have a registered Dart Development Service (DDS) instance and is not currently serving Dart DevTools.

Platform:

IMX8QXP
IMX-WAYLAND

Flutter elinux release 3.13.0

Flutter target devices:

flutter-elinux devices
4 connected devices:

Linux (desktop) • linux • linux-x64 • Ubuntu 20.04.6 LTS 5.15.0-101-generic
eLinux (desktop) • elinux-wayland • flutter-tester • Ubuntu 20.04.6 LTS 5.15.0-101-generic
eLinux (desktop) • elinux-x11 • flutter-tester • Ubuntu 20.04.6 LTS 5.15.0-101-generic
> eLinux (mobile) • gridania-pvt1 • flutter-tester • ion-imx-wayland

Step to Reproduce:

flutter-elinux create sample
cd sample
flutter-elinux pub get
flutter-elinux run -d gridania-pvt1 --profile -v

Regarding to your trial on Rpi, i just confused about why did your target board already installed "Dart DevTools" and it will be activated automatically while executing flutter app.

or after "💪 Running with sound null safety 💪"

It is being executed on Host???

nguyenlkdn · 2024-04-10T10:31:43Z

Practice done already, with below notes:

I need to attach "--debug-url" manually after application started

Target Device:

LD_LIBRARY_PATH=/usr/share/flutter/3.19.3/profile/lib/ flutter-client --bundle=/usr/share/flutter/ion-hmi/3.19.3/profile/
flutter: The Dart VM service is listening on http://127.0.0.1:38867/LdVG8OhkIx8=/

Host PC:

Need to go into the project folder
Need to be sure PortForward already started before starting Host Dart Devtool

Ex: in my case is ssh -o ExitOnForwardFailure=yes -L 127.0.0.1:38867:127.0.0.1:38867 [email protected]

flutter-elinux attach --debug-url=http://127.0.0.1:38867/LdVG8OhkIx8=/
Syncing files to device eLinux...                                   6.2s

Practice on Flutter-eLinux release 3.9.13. Thank you!

@HidenoriMatsubayashi I am not sure why did my environment haven't started Devtools automatically as your practiced

You should use The Flutter DevTools debugger and profiler on eLinux is available at: http://127.0.0.1:9100?uri=http://127.0.0.1:43373/-fXmCK4fbG0=/ one on Host PC.

I'm not sure what your issue is here...

I've confirmed that flutter-elinux with a remote-device works fine.

Ya i mean is we able to connect for debugging on target already after we attach debugger manuallly

flutter-elinux attach --debug-url=<Link to VM Service on target board>

I just concerned is why did it is not started automatically on our environment.
Maybe it is environment issues, thank for your confirmed.

HidenoriMatsubayashi · 2024-04-11T03:44:39Z

Please try the followings to break down the issue.

Use the latest version of flutter-elinux
Use other devices such as Raspberry-Pi4/5

HidenoriMatsubayashi · 2024-04-15T12:00:36Z

I'll close this issue as there is no additional update/comment.

HidenoriMatsubayashi · 2024-04-15T12:41:35Z

Re-opening.

Pasting what i had in the other issue

Looked through a bit of the other issues but haven't been able to resolve what I am seeing.

flutter-elinux run -d v1200
Launching elinux/flutter/main.dart on eLinux in debug mode...
Uninstall vis_vision_app from v1200.
Uninstallation Success
Install vis_vision_app (build/elinux/arm64/debug/bundle) to v1200
Installation Success
Launch vis_vision_app.name on v1200

The discovery uri never shows up in the regular log. But if i run with -v

[+5191 ms] Installation Success
[        ] Launch vis_vision_app.name on v1200
[+1231 ms] VM Service URL on device: http://127.0.0.1:40937/MWJ-2vYYMDg=/
[   +1 ms] executing: ssh -o ExitOnForwardFailure=yes -L
127.0.0.1:40937:127.0.0.1:40937 [email protected]

Going to that url I get this.

This VM does not have a registered Dart Development Service (DDS) instance and is not currently serving Dart DevTools.

Other info, I am cross building from x64 to arm64 using custom sdk and yocto.

WDoughty · 2024-04-15T15:21:43Z

I used that url from the verbose log and did the same process with running the flutter-elinux attach from my development machine and I was able to get dev tools. Not sure why its not running the attachment by itself. Here is the forwardPort for this custom device.

"forwardPort": [
        "ssh", "-o", "ExitOnForwardFailure=yes",
        "-L", "127.0.0.1:${hostPort}:127.0.0.1:{$devicePort}", "ccs@<display IP>"
      ],
"forwardPortSuccessRegex": "Linux"

HidenoriMatsubayashi · 2024-04-15T20:45:25Z

"-L", "127.0.0.1:${hostPort}:127.0.0.1:{$devicePort}", "ccs@"

Typo: {$devicePort}
=> Correct one is ${devicePort}

WDoughty · 2024-04-16T13:48:56Z

Good catch, but that is also how i have it in my custom devices. Working between different devices
