Hello,

While trying to prepare images for Beaglebone Black with "ltp-testsuite" included (keeping other parameters to their default values),the build process breaks .


-----------------------------
Error Message with Default Settings:
-----------------------------

Updated the value of "BR2_TARGET_ROOTFS_EXT2_SIZE" from 60M to 64G.
An error message mentioning 
"part rootfs size (536870912) too small for rootfs.ext4 (68719476736)"
 (as below) appears in the build log.

--------------------------------

What would be the apt value for this parameter??
Should any other parameter be accordingly modified?? 
Please advice.
