Also, I found a typo in the documentation:

PC $> lunch aosp-<BoardId>-userdebug

Hi @Mikalaj Karhin​ ,

If the patches don't apply automatically, could you please try to do it manually to get the returned error and also check on which kernel-headers

and kernel SHA1 they are applied ?

Regarding the typo in the Wiki, <BoardId> is a variable : put your mouse cursor on it to get its values : as you work on Eval board, <BoardId>=eval.

BR,

Christophe

lunch aosp-<BoardId>-userdebug

Should be:

lunch aosp_<BoardId>-userdebug

[Christophe Guibout]

OK, modified, need to wait next synchro to see the result.

thanks !

How to manually apply patches and get a more informative log?

I don't see any options in "applypatch".

[Mikalaj Karhin]

Oh, sorry for the fake report. I didn't set git config (email, name) on a dev server. Everything is ok, now.

I think applypatch script should show more informative log at these cases :)
