Zybo Z7 linux boot

[aashish]

Hi all,

I recently bought a new Zybo Z7-10 board, I want to boot linux in it (With GUI desktop like linaro), and then want to control LEDs, Switches etc by Python/C/C++ codes.

I could not find a well documented beginner tutorial targeting Zybo Z7-10 yet, so I am trying this : https://www.instructables.com/Embedded-Linux-Tutorial-Zybo/

Now the Problem :

I downloaded the zybo_base_system.zip from https://reference.digilentinc.com/_media/reference/programmable-logic/zybo/zybo_base_system.zip I then opened it by Vivado 2017.4 then upgraded the design as written in the tutorial above.

But when I hit the Generate Bitstream it failed, I am getting the following errors,

ImplementationPlace Design[Place 30-58] IO placement is infeasible. Number of unplaced terminals (8) is greater than number of available sites (0).
The following are banks with available pins: 
 IO Group: 0 with : SioStd: LVCMOS18   VCCO = 1.8 Termination: 0  TermDir:  In   RangeId: 1  has only 0 sites available on device, but needs 8 sites.

Below is the partial placement that can be analyzed to see if any constraint modifications will make the IO placement problem easier to solve.

I am a absolute beginner to Zybo and Vivado,  please help me how to proceed.

Thanks in advance
