i'm using the pre built Android image version:
With android_jb4.2.2_1.1.0-ga_image_6qsabresd prebuilt image and MFG tool Mfgtools-Rel-13.01.00_ER_MX6Q_UPDATER.
However after MFGTool completes to write the image, I change the SW switches and try to get anything from the debug uart. At least to get into uboot. But nothing is written on the uart, and system does not start at all.
