APM PLANNER on Chromebook

Trying to install apm planner on a Chromebook (303c12-a01) (ARM processor?) Have Unbuntu 14.04 XCFE installed. Followed DIY instructions. Sudo apt get install git qt5…etc–returns cannot find qt5 package errors. Tried installing qt5 from ubuntu sites and are having no luck. From reading it appears qt5 is actually part of 14.04, is it? Possibly not being recognized, or is it something to do with ARM architecture. Not sure if should be trying to install just Linux version, or Rasp Pi version. Even when trying to install Pi version doesn’t work fails (can’t remember exact error, but I recall something about widgets, which again is qt5 related isn’t it?) Even tried Tower as app in Chrome OS using TWERK had no luck, opens window and freezes on startup.

Have literally spent hours googling and trying to install packages on ubuntu and haven’t gotten any further.
Could anyone tell me if they have gotten any version of planner working on Chromebook?
What version should I be trying?
And any solution to getting qt5 packages ‘being found’ and installation would be GREATLY appreciated.

Definitely the RPi2 version.

Can you send the results of this command?

$ cat /etc/apt/sources.list

This is what it returned. I hate to say I know very little about Linux, so please bear with me.
Thanks Dave

Hmm…are you sure you don’t have Ubuntu 12.04 installed on your Chromebook?

Precise would be 12.04 wiki.ubuntu.com/Releases

(trusty)davfar@localhost:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 12.04.5 LTS
Release: 12.04
Codename: precise
(trusty)davfar@localhost:~$

Boy, do I feel dumb…I thought (trusty) showed I installed 14.04. I guess I must have used -n trusty instead of -r trusty on crouton installation, installing chroot name not version. Sorry, like I mentioned first time doing this, lack of experience…
Will upgrade and try again…
Thanks!
Dave

I forgot one other question,
How should I install Pi version? Just download .deb file and use dpkg?
Or use DIY instructions, will it automatically choose Pi version?

Thanks

It should work with the downloaded .deb, but let us now if you have issues. Good Luck :slight_smile:

Did total full clean install of 14.04.
Load apm pi2
dpkg
apt-get -f install
dpkg
ran…YAYYYYYYYYYY!
Got warning to add user for dialout,close…
adduser dialout
ran…FINALLY!!!

Of course still have to try connecting to quad and operations
but looking good so far.

THANKS for all help and guidance --Greatly appreciated!
Dave

Unfortunatley hit a wall again. Tried connecting to quad (cx 20) received error…

error opening port:permission denied
(after hitting connect)
tried adding davfar to dialout again, returns already a member

I’ve included terminal info after starting apm, hopefully someone may be able to aim me
in the right direction.

Would appreciate any help…
Thanks Dave
(Does connect on MP - Windows desktop)


Should fix it.

Hi Bill, thanks for responding,

tried remove modem manager, responded not installed

Does ttyACM0 show up when you enter ls /dev/tty*

(trusty)davfar@localhost:~$

Hi Bill, did some searching and found info about running from root,

sudo -i

ran and added root to dialout

hey…it works, now connects fine

Is there a risk to running from root? should I change something, or is there something I can change so does not have to be ran from root?

Thanks
Dave

Running as root should be fine…but not always recommended. Try running as user davfar again.

It’s a good chance user root has privileges that user davfar does not.

You can check if some other process has a device open using lsof (List of Files). the example below show I have the device open with ‘screen’ command

bonney@slimvan:~$ lsof /dev/cu.usbserial-DN0019M3 COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME screen 14735 bonney 5u CHR 17,11 0t992 1169 /dev/cu.usbserial-DN0019M3 bonney@slimvan:~$
Second, you should check that you did add the user to the right group

bonney@bonney-ThinkPad-T60p:~$ groups bonney bonney : bonney adm dialout cdrom sudo dip plugdev lpadmin sambashare bonney@bonney-ThinkPad-T60p:~$
Post your results might help us :slight_smile: Thx

Thanks for replys guys,

carpy- tried running as davfar, still getting connection error -permission denied

bill- sorry, format error when entering ls command,forgot space after

is that number correct or is it machine port specific? Sorry I’m so linux illiterate…
Thanks

I should have mentioned you should have type

lsof /dev/ttyUSB0 # This is the 3DR modem or lsof /dev/ttyACM0 # This is the Pixhawk not the /dev/cu.usbmodem as that is the device naming on the 3DR Radio on OSX

PS: in the BASH code snippets # is the comment symbol so you don’t need to enter it (everything to the right of it is ignored)
PPS: Try this codecademy.com/en/courses/l … mmand-line if it suits you.

Hi bill,
Think I entered command wrong again on code posted last time…
Thanks for link on code, definitely nver hurts to learn something new (would be a good winter project to get a solid grasp on language)
Yes, in first post of connection error was ttyACM0 with hardwire connection, finally got telemetry installed and it connected ttyUSB0. (both connect when ran from root but not from user davfar)
