How many gpios are available on Parallella-16 (Zynq-XC7Z010)

Postby peterpatrov » Fri Aug 29, 2014 2:06 pm

Hi everybody! I've recently purchased Parallella-16 with the small Zynq-7010 and want to design a daugther board for gpio connector. I'm not shure how many gpios are really connected to the Zynq-7010. Unfortunately I could only find schematic for the Zynq-7020 on http://www.parallella.org/board/. In the git-repository ...\parallella_hw\parallella-hw-master\boards\archive\gen1.0\schematic there is a schematic for Zynq-7010 and i can see that only first 12 gpio pairs are really connected to the PL side of Zynq. I would be very thankful to anyone to confirm that Parallella-16 with Zynq-7010 has only 24 pins (or 12 pairs) connected to gpio expansion connector.

If you are using KiCad feel free to start with the "Paracard" template here.

From a schematic perspective the only difference between the 7020 and 7010 is whether or not Bank 13 is "live" or just a bunch of internal no-connects. The PCB is the same for either one. The only signals on bank 13 are GPIOs from 12 to 23.

Also, rather than using the obsolete schematics from the archive you should use the latest one from here.

Hi everybody
I want to connect an adc chip with 14 pairs lvds port but my parallella has only 12 pairs and need just two pairs more :D and plus embedded version price is too high for only two pair pins! how could we manage this problem? Any suggestion would be appreciated!
tnx
