Will Debian Bullseye come? #1554
Comments
|
Not likely (unless someone wants to sponsor me to work on it). |
|
I wanted to try to update it myself, any suggestions to how I might do it? |
|
The first step would be to get https://github.com/ev3dev/lego-linux-drivers updated to the latest kernel and make sure everything still works. Then try building the image from https://github.com/ev3dev/docker-library and see if there are any more ev3dev-specific packages that need to be updated and rebuilt. |
|
Thanks! I’ll try that! |
@pythoncat1 I am also curious about this...did you happen to make any progress with either Bullseye (or Buster)? |
|
@Growflavor Unfortunately no… i’m not really familiar with this sort of thing 😅 |
Ok thank you for the update! Some reference info for anyone else curious or tinkering: (or perhaps incase updates or python packages eventually stop being able to be installed, for example, via 'sudo apt install python3-numpy' on the released EV3dev Debian 9 "Stretch" armel version...) --as discussed in #1228, for basic EV3 core set sensors/motors the EV3dev beta "Buster" (which uses python 3.7 and apparently has Brickman 0.10.2 in the default docker pull rather than 0.10.3) does boot, updates via internet, connects to VScode, & appears to run at least basic programs (so far I've just used basic motors & sensors) The EV3dev Beta Debian 10 "Buster" SD card image can be made using Brickstrap (just by following the provided instructions & terminal commands): https://github.com/ev3dev/brickstrap ========== ev3dev-sysinfo ========== --also, there is a potentially interesting "user created update" (i.e. tinker & use at your own risk & with caution...) of EV3dev Debian 9 "Stretch" image that has Python 3.9.16 in the discussion at #1558 ...it does boot, etc.: I did succeed at flashing a SD card with the provided 14GB .ima image using the trial version of WinImage & have started tinkering... https://wiki.debian.org/LTS https://wiki.debian.org/LTS/Extended |

note for tinkering fun with ev3dev2 & Python 3.9.2 with the Debian Bullseye beta2 based on the old Kernel version: 4.19.85-ev3dev-3-beta2-ev3 @StepanTheFlowey made a brickman fork that will build on & StepanTheFlowey/brickman#1 (comment) With the disclaimer & caveat that the following image(s) are "tinker & use for your own 'breaking' fun/learning risk" google drive link to ZIP file with ev3dev11v7.img that can be flashed directly to SDcard by Etcher: https://drive.google.com/file/d/1ryNuD96bsXy7Kkv1_DASmhP9_wthxCon/view?usp=drive_link .zip sha-256: 917BF029AAF5EC88C70300BD1D84CD2E95AC1C46B49C40515209BD625379D255 .img sha-256: D6DE416D7DED2636B229B2B1DF10E5EF99E5C6B7D5CB1DAE829DC6A0B53A6AD1 this image was built using: sudo brickstrap create-tar growflavor/ev3images:latest ev3dev11v7.tar sudo brickstrap create-image ev3dev11v7.tar ev3dev11v7.img ========== ev3dev-sysinfo ========== Note 1: for us PuTTY & VScode all connect with this above image by USB to ethernet adapter local LAN, USB cable connection to Win 11 computer, & the EV3 onboard Bluetooth. However, with connections to one of our EV3 bricks we had to increase the timeout value to 90 seconds in the VScode ev3dev Browser settings:
Note 2: fun fact -- VScode has a jupyter note book extension so you can have a notebook open directly in VScode served from the same .venv you use for the pylance interpreter & use RPyC 5.3.1 to directly control your EV3 by notebook code cells You can add RPyC to this Bullseye image:Note this sudo use of pip is 'not an ideal' method (but it works ok in this case). sudo python3 -m pip install rpyc==5.3.1
hostname -I
robot@ev3dev:~$ hostname -I
192.168.1.110
robot@ev3dev:~$
then activate the EV3 RPyC server using the IP shown by hostname -I:
sudo python3 /usr/local/bin/rpyc_classic.py --host=192.168.1.110Note 3: using apt is painful onboard the EV3 especially with Bullseye, so easier to: update the image using a docker container:--make changes/updates in a docker container on a machine with a favorite brickstrap/docker setup: commands below are for docker running on linux... details about brickstrap: https://github.com/ev3dev/brickstrap sudo docker pull growflavor/ev3images:latest
sudo docker tag growflavor/ev3images:latest ev3d11old
sudo docker run --platform linux/arm/v5 -it ev3d11old su -l robot--you will get a robot@ prompt, make the updates/changes you want inside this container, then logout from the robot@ prompt --then commit the docker container you just updated to a docker image (docker ps -a will show the image(s) & ID#): sudo docker ps -a
sudo docker container commit ID#_of_your_updated_container_e.g.123eeed582c2 ev3d11new:latest--then use brickstrap to make a new .img from your updated docker container to flash with Etcher, for example: sudo brickstrap create-tar ev3d11new:latest ev3dev11new.tar
sudo brickstrap create-image ev3dev11new.tar ev3dev11new.imgYou may return to your stopped container (use your container's name i.e. not quizzical_wright ) to make further changes/updates anytime by starting it: sudo docker start -i quizzical_wrightor if it is still running you can activate a shell to resume work with syntax like: sudo docker exec -it quizzical_wright /bin/bashyou can also copy files out of the container with syntax like this: sudo docker cp quizzical_wright:/usr/local/src/brickman_0.11.0+fl0wey1_armel.deb .Note 4: for the moment, sudo docker pull growflavor/ev3images:latest should pull this sha-256#: Digest: sha256:e0b53625b2375a4aec942a53860cc2d15f4043693bbc4ed78fa756687c212d76 Note 5: no micropython in this image since appears it would need to be rebuilt at least with libffi7 & libmagickwand-6.q16-6 to even have a chance of working with Bullseye Note 6: fun fact -- "sudo chvt 6 sudo conspy" #880 (comment) Note 7: If you learn or discover or add anything cool...let my son & I know! |

@Growflavor Very interesting! Will try it and tinker as soon as I can! |

Also, for anyone interested in tinkering with the docker library Stretch image... sources for backports & security indicated >100 updates available (see below)... so , here is a link to EV3devDebian9Stretch image based on the EV3dev docker library Stretch image...
ev3dev9mlv02.zip Ev3dev9mlv02.zip sha-256: Ev3dev9mlv02.img sha-256: After flashing the .img to SD (e.g. via Balena Etcher), on first boot, the boot sequence may pause with a notice in the micro text on the screen that root access is locked. In my case, I press the center button = 'Enter" to continue boot, then reboot from Brickman menu once the 1st boot completes. After the reboot, I then connect to VScode etc.

Interesting 👀 |
some 'tinker thoughts':
a) you can easily tinker with 'make altinstall' of Python from source in the docker container (see 4) below as an example). b) As for Debian packages: -- if one needed a feature from a newer Debian package, a first step might be to see if that feature was made available via a backport package, then install just that backport & its dependencies via apt: https://backports.debian.org/Instructions/ -- if just using the python-ev3dev2 package, one 'tinker' path might be to update the Debian version to 'Bookworm' via docker container (in this case the newer Debian packages would be running on the older 'as is' 4.14 or 4.19 armel EV3 kernel) then create a python venv & pip install python-ev3dev2 -- if no major syntax or methods have been dropped by python 3.11.2 that might 'work enough to be useful'...

Question
Debian released Buster and Bullseye but ev3dev is stuck on stretch. Does there is any plan to upgrade? Or is this project discounted?
