Hi @Arty7_Lover,

I have seen this error when the Mode Jumper is set to SD instead of JTAG. I have also seen this error when the ZYNQ processor is not correctly configured. 

In you other post here it appears you are altering the zynq processor setting.

Please attach a screen shot of your vivado block design and your sdk.

best regards,

Jon

Hi @Arty7_Lover,

Here is a completed and verified Hello world project for the Arty-Z7-20 using Vivado 2018.3 and the Digilent board files. Please use the Digilent board files as shown in the attached screen shows. The screen shots show the process taken to complete the project.  Here is the data sheet for the IS43  TR16   2 5 6 A - 1 25KB DDR3 part on the Arty-Z7-20. You can see this on page 11 of the schematic here.  I believe it is the commercial version. Its  my understanding that in our boards files we used  the pre-loaded  MT41J128M8JP-125 DDR3 controller since it interacts with the on board DDR3 memory correctly and we could configure it to the spec's of the on board DDR.  The reference manual shows the DDR3 to be 512 MB(Mega BYTES) which is the same as 4 Gb (Giga bits).   

best regards,

Jon
