devtool question/issue

Hi,

I've been following along on this youtube video created by a Yocto
developer:

https://youtu.be/nqHylLP2NmA?t=1592

I can reproduce everything presented until it comes to using devtool (as
shown at the time index in the link given above). When attempting to run:

devtool add git://blah-blah-gitrepo

I get the error:

ERROR: workspace layer not set up

My understanding from the documentation is that the "workspace" layer gets
created (if it doesn't exist) when running devtool with a command such as
add.

Since I'm new at using Yocto, it's likely that I"m missing something
fundamental here.

Any help/suggestions would be appreciated

I always start with

devtool modify <package>

This sets-up the workspace,  puts the package source code in workspace/sources, inits git, etc.

Thanks for the suggestion. I gave it a try but I still get the same result/error :(

After some experimentation it appears that devtool does not like running from a filesystem volume that does not contain my home directory.

My current setup on a virtualized host has the following volumes:

Filesystem Size Used Avail Use% Mounted on

udev 32G 0 32G 0% /dev

tmpfs 6.3G 5.7M 6.3G 1% /run

/dev/sda 25G 11G 13G 46% /

tmpfs 32G 0 32G 0% /dev/shm

tmpfs 5.0M 0 5.0M 0% /run/lock

tmpfs 32G 0 32G 0% /sys/fs/cgroup

/dev/sdc 148G 39G 102G 28% /mnt/YB

tmpfs 6.3G 0 6.3G 0% /run/user/1000

My home directory is located on /dev/sda - devtool works for yocto projects on this volume

/dev/sdc - I added this volume so that I'd have more space while using yocto, but devtool complains and doesn't run here. I deleted the contents of /dev/sdc and re-tried following the tutorial given in my initial post. I can reproduce (e.g. create and run qemuarm images) everything upto the step where devtool needs to be used.

The short term solution would be to increase the size of /dev/sdc but this requires moving up to a more expensive plan from my cloud provider.

Any insight as to why this occurs

I found the issue that was causing my problem. Just an FYI if anyone else happens to run into this.

There was a file named ".devtoolbase" in /mnt/YB. I think this was a remenant of some previous work I was doing with yocto. I'm not sure what the purpose of this file is but once I removed it devtool no longer errorred out.

Oh great, thanks for the heads up. I am actually the one who did the
video, and just returned into office mondayishly and would have tried
probably this afternoon. But that I would have never found, as I
usually start out in clean slate containers, and I use devtool a lot
in there with builds even scattered out over multiple mount points.So
glad you figurede out and took the time to share!
