This might seem stupid at first but I am trying to do pycom developpment from a raspberry.
Reason is simple. The whole system lopy4 + raspberry (openplotter) are meant to be installed on my boat for security monitoring (intrusion and water level), navigation logging (that's the raspberry's job), and occasionally retrieve raspberry data remotely
Both will be connected together through the usb port. The lopy4 will be able to turn on the pi remotely record some nmea data (wind, etc... ) and turn it back off
Anyway since the 2 devices will be connected for life I thought why not do the development on the pi and so if I need to make changes later on while on the boat I'll be able to do so.

Anyway I just installed the arm version of VScode and installed pymakr on top of it both successfully !!! I can see the lopy serial(usb) connection but apparently vs nor pymakr seem to keen on detecting it. the bottom menu doesn't appear and on the top right when I click on "pymakr run current file" it says pymakr.run not found...

Any hints or dependencies missing I should have installed or is it not possible at this time?

Thank you in advance

I got vscode for armhf here:
https://code.headmelted.com/
Version: 1.29.0 (user setup)
Commit: c6990d2ed650612cfffcebedad439e61a34c7779

Electron: 2.0.11
Chrome: 61.0.3163.100
Node.js: 8.9.3
V8: 6.1.534.41

installed on:
PRETTY_NAME="Raspbian GNU/Linux 9 (stretch)"
NAME="Raspbian GNU/Linux"
VERSION_ID="9"
VERSION="9 (stretch)"

ID_LIKE=debian

Pymakr is 1.0.4 as far as I can see from the extensions tab.

and it also says command pymakr.upload not found

Thank you for your help.

p.s.: am I the first doing this or have you already heard of people doing it from a raspberry?

So you can solve it by downgrading to 1.28.2, or if you don't want to, by rebuilding the serialport.
Easiest way for the latter is changing one line: var electron_version = '2.0.7' to '2.0.11' in ~/.vscode/extensions/pycom.pymakr-1.0.4/scripts/install.js and then run npm install again from the pycom.pymakr-1.0.4 folder.

I just did as you said and changed the install.js because I don't really know how to get 1.28.2 for armhf:
using
curl -s https://packagecloud.io/install/repositories/headmelted/codebuilds/script.deb.sh | sudo bash
sudo apt-cache showpkg code-oss
only shows 1.29 versions....
Apparently it seems there is only 1.29 versions for debian/stretch and 1.28 is Ubuntu/xenial.
Why does it have to do with the windows manager????

Anyway I had some progress by modifying the electron_version to 2.0.11 and it seems the connection works and the REPL is now working in the consol !!!!!
So serial works and most commands work. (wifi, firmware version, etc)

Except the Global settings, which doesn't do anything (I am expecting to see some file being opened) and looking everywhere I can't find find the json file on drive... although config.js seems to be have a default version of it.
"upload or download project" are also not responding nor throwing any errors.
I am not clear about how to indicate to the vscode that the current folder is supposed to be a project (except by setting the "sync_folder" to the pymakr.conf)
"Run current file" seems to work though...

Also It says that pymakr.conf file format is wrong but I put it in a json validator and it seems to be fine..

here is a screen shot(not sure how it would help)..

Thank you for your support...

Thank you

(By the way, you can leave the 'sync_folder' set to an empty string if you want to sync the root folder of the opened project.)

On linux, the config file should be here: /Users/<username>/.config/Code/User/pymakr.json. Could you check if that is there, and if not, try to create it? Contents with defaults should be this:

    "address": "192.168.4.1",
    "username": "micro",
    "password": "python",
    "sync_folder": "",
    "open_on_start": true,
    "safe_boot_on_upload": false,
    "sync_file_types": "py,txt,log,json,xml,html,js,css,mpy",
    "ctrl_c_on_connect": false,
    "sync_all_file_types": false,
    "auto_connect": false

}

Pymakr should create this by default. I'll check if there is a mistake there that occurs on linux when installing for the first time.

Just reporting that It works actually the folder is oddly named : Code - OSS (headmelted)/
(yes with the sort of "spaces")

so to make it work I just did a symlink in: .config
ln -s Code - OSS (headmelted) Code
and added the json file and I can now code/upload/download my lopy4 from my raspberry 3B+ ;)

Thank you for your help
