Failure to program FPGA - Zedboard

I'm learning the tools (Vivado and SDK) and so I'm doing just a small project consisting of one for cycle.

The synthesis, implementation and bitstream generation all pass in Vivado, but when I try to program the FPGA in SDK an error occurs:

Program FPGA failed

Reason:
Failed to download the bit file

Failed to configure device 2 (xc7z020) with bitstream /home/.../workspace_SDK/Simple_for_wrapper_hw_platform_0/Simple_for_wrapper.bit
Reason: Programming failed

I saw a couple of posts with the same problem and so I tried a suggestion that was to try and program the FPGA in the Vivado. The result:

ERROR: [Labtools 27-2270] Target localhost/xilinx_tcf/Digilent/210248495746 is no longer available.
Check cable connectivity and that the target board is powered up then
use the disconnect_hw_server and connect_hw_server to re-register this hardware target.

Every other example project runs fine and I can program the FPGA in both SDK and Vivado.

Do I have a problem in my bitstream file?And if so why didn't Vivado say so?

It looks to me like you have a cable problem.
Check cable connectivity and that the target board is powered up
I suggest the following:

Is your microUSB plugged into the correct USB-JTAG port? Should be J19, up by the audio connectors. Make sure you don't have anything plugged into J15.

Did you put the MODE jumpers in JTAG mode? All 5 should make the SIG/GND connection.

Is the board powering on properly?

If it still fails in Labtools, then try a different microUSB cable or use a JTAG pod if you have one, plugged into J15.

Thank you for the answer.

If that's a cable problem then why can I program the FPGA with another example but not with this one that I made?

But u00CE checked your 4 points and all is ok. Except for point 1: here, do you mean J17?

Oh and just to make sure we're talking aobut the same thing, here's an high resolution image:

I have the same problem with Device xc7z020_ which is:
ERROR: [Labtools 27-2312] Device xc7z020_1 is no longer available.
I can upload other projects, but for one specific project I get this error.
Any solution please?

Yes, J17 is correct.

If you can load other projects it does indicate that your project is the issue. Check that your project has the correct Zynq device AND package. It should be xc7z020clg484-1. Did you make sure that you have used the correct board file (for ZedBoard and not some other 7020 based board) to generate your design?
