[meta-ti] Problem to build core-image-sato

[winiston at futuraautomation.com]

Dear,

Now I am using yocto  in our project. I am satisfied with yocto build system (poky) . 

Our system configuration :

Host system  : Ubuntu 14.04  (Virtual Machine )
Target system :  am437x-evm

The following errors are spiting out while creating core-image-sato.

winiston at winiston-VirtualBox:~/poky/build$ bitbake core-image-satoLoading cache: 100% |###########################################| ETA:  00:00:00

Missing or unbuildable dependency chain was: ['core-image-sato', 'packagegroup-core-x11-base', 'packagegroup-core-x11-xserver', 'xf86-input-tslib']

Summary: There were 2 ERROR messages shown, returning a non-zero exit code.

What could be the reason? How do I solve this issues? 

second clarification is ,

Can I use “Navit” software in the core-image-sato image? If yes, What is the procedure?

Note: “Navit” is the open source navigation software build for arm/x86 based project.
