[Toaster] "Existing git repository" error or How to build a custom layer?

[Romain Bazile]

Hi Belen,


Thanks for answering.

I finally had some time to go through testing again!

I cleaned the poky folder (removed build dirs), dropped the database and 
started again.

I answered inlined to your questions.

Yes, exactly! I used the Krogoth branch.

So, this is what I tried to do (I already have another project with 
another machine and a successful build, but no other build going on):

 1. New empty project, with Krogoth release, named gateway-rasp-krogoth
 2. Import of meta-raspberrypi, same settings as yours
 3. machine to raspberrypi2
 4. build done

This left me perplexed, so I tried again.

One difference though, I made a mistake while typing, and not thinking 
straight I put "HEAD" as a revision for the repository.

It did not like that and crashed the build with the same error.

And, when I tried to put the name of the revision back to master, it 
would apparently save the setting, but when I reload the layer config 
page, the setting went back to HEAD.


So, I think the mistake was mine (I must have put "HEAD" instead of 
"master"). But it seems like toaster doesn't save the git revision when 
I try to change it.


Thanks,



Cheers,
