Hello everyone,

I'm new to isar and today I made an attempt to build the default image 
with it. I installed all the host tools necessary as it is written in 
the docs. Then I followed strictly the doc/user_manual.

My host OS is debian jessie.

Unfortunately when I try to build an image I get this error:

/bitbake isar-image-base//
//Parsing recipes: 100% 
|###########################################################################################################################################| 
Time: 0:00:00//
//Parsing of 11 .bb files complete (0 cached, 11 parsed). 110 targets, 0 
skipped, 0 masked, 0 errors.//
//NOTE: Resolving any missing task queue dependencies//
//ERROR: Nothing PROVIDES 'linux-image-${KERNEL_NAME}' (but 
/mnt/elbe/Isar/isar/meta-isar/recipes-core/images/isar-image-base.bb 
DEPENDS on or otherwise requires it)//
//ERROR: Required build target 'isar-image-base' has no buildable 
providers.//
//Missing or unbuildable dependency chain was: ['isar-image-base', 
'linux-image-${KERNEL_NAME}']/

So I added KERNEL_NAME ?= "armmp" to the local.conf but now I get 
another error:

/bitbake isar-image-base//

the default tty in the conf/machine for qemuarm is set to ttyAMA0. My 
user is in the sudoers file as showed in the docs. I don't understand 
what I'm doing wrong here.

Hope you can help.
