Programming Tool Problem - Will not boot Ramdisk

Question asked by Paul DeMetrotion on Aug 23, 2013
Latest reply on Feb 25, 2014 by Yixing Kong

I am having difficulty programming an on-board SPI-NOR device on a custom i.MX6Q board.

I have built all of the appropriate manufacturing files and placed them in the proper directory. I am using the MfgTool2 program. Everything appears to be working properly but when the kernel gets to the end of execution, it attempts to mount a file system rather than executing the Ramdrive currently in memory. This failure causes none of the Updater commands to be executed.


Any suggestions will be greatly appreciated!


Here are the important parts of the console output:
