Zed Board XADC Auxiliary Channel

jayasankarvn

How do you access the 16 auxiliary channels of XADC ? Can I use the existing I/O pins as auxiliary inputs ? I couldn't find any options to change the sites of auxiliary channels. Should I use an FMC breakout board to access all analog channels ?

    I referred almost all possible documents. But one thing is not clear to me. If I use Vp/Vn or vauxp0/vauxn0 or vauxp8/vauxn8, the external analog signals can be connected through the pins in xadc header. If I want to extend the auxiliary channel number, where do i connect the analog signals ? Should I use an fmc break out board to access those ? Or can I convert the Pmod I/Os to auxiliary channels ? Please do reply. I've been spending time for last two weeks to clear this doubt.
