Hi All,


I just tried my first Yocto build on the iMX6 SDB.  How easy was that!  GREAT job!!!  After LTIB headaches over the years, it is quite refreshing to follow the instructions, download as instructed, build, have it run to completion without errors, and work first time.  HUGE LEAP FORWARD! THANK YOU, THANK YOU, THANK YOU!!!  For those who haven't tried it, you owe it to yourself...


I was running the fsl-image-gui image, and during my initial playing around, the following appeared on the serial console:

Also, is there a list (other than the directory listing) of what is in each image? For example:
