Hello,

I am trying to create a new bsp layer for a customized board.

After running the commands: Yocto-bsp create  ctp arm,

I am seeing the following errors:

evk1206@evk1206-VirtualBox:~/Projects/Yocto/build-ctp$ yocto-bsp create custom arm

Checking basic git connectivity...

Done.

Would you like to use the default (4.8) kernel? (y/n) [default: y] y

Do you need a new machine branch for this BSP (the alternative is to re-use an existing branch)? [y/n] [default: y] y

Getting branches from remote repo git://git.yoctoproject.org/linux-yocto-4.8.git...

Couly anyone let me know how to fix the issue.

I tried using both the master and morty-16.0.1  branches of poky.
