    Understood; it wouldn't be fair for someone to get one that didn't understand what is expected of them with regards to beta testing hardware like this.

    I have multiple copies of the development environment installed on my linux box by having them under different user IDs. I need to do that because I'm working with three radically different controller boards that have conflicting setups in the development environment.

    @Paul,
    I understand that the pins for sdhc are already taken of pin list.
    Q: will there be a on-board uSD (e.g. lower side?) or are there some pins/pads for external uSD?

    I do currently have the 8 pads in the design. They create a routing nightmare! I probably can't place them at the ideal location, but trying....

    Wow, looks like they trimmed it by ~200 pages.

    Seems 180 of the removed pages are from table of contents, which was ridiculously long on Rev 1 due to fully expanding all the sub-sections. Doesn't look like they actually removed any significant info.

    It's still filled with copy-paste errors from iMX6, like "the maximum chip supported frequency 1.0 GHz" which moved from page 411 to page 957. Still has lots of confusing stuff, like the SRC diagram (who draws such a stupid diagram?), which now appears on page 1242.

    At least they changed to the sensible organization of chapters, rather than alphabetical by module acronym.
