In the Hardware Overview (https://udooboard.github.io/X86-Docs/Hardware_Reference/Overview.html) there are two undocumented connectors, both on the top side of the board: A: near the upper edge, somewhat in the middle, behind the right USB3.0 and the audio connector B: near the lower edge, almost completely to the right, between the right DP+ connector and the mounting hole. Could you please provide the purpose and pin-out of this connectors. Thanks, Goetz.
In the diagram, B has the same pin count as the JTAG connector on a standalone Arduino 101. Also, a JTAG is listed in the block diagram but not labelled anywhere in the layout overview picture. So it's probably that. I am not sure what A could be.
The one near the upper edge (A) is the connector to program the STM32 micro. The one near the lower edge (B) is the JTAG connector. For an exhaustive explanation of the hardware, please wait just a few days and we will provide the hardware manual.
It's been two weeks. Any word when that "exhaustive explanation of the hardware" will be released? Thanks.
It is not exhaustive but more than 2 weeks ago: http://www.udoo.org/docs-x86/Hardware_Reference/Resources.html
