ok both the jz4775 and ic1t cpu cards pass routing and plane (connectivity) checks, it's what i've been spending my evenings on, over the past couple of weeks. i have to consider replacing the SD/MMC card slot on the IC1T board with a BGA 11mm eMMC because SD/MMC is not as reliable, eMMC has 8 data lines and will be faster. BGA 159 pin eMMC will just about fit and will simplify the design slightly.
more later, will create PCB images etc.

Based on our experience with board we created it is good decision.
