FUSE_DNA

Jump to solution

Hello there,

I know I can read the ZYNQ-7000 SoC FUSE_DNA register value from the external JTAG port

I want to know if I can somehow read the FUSE_DNA (Attention!!! the 64-bit FUSE_DNA, not the unhelpful 57-bit PORT_DNA) with the PS processor...

I think I can add a debug bridge in AXI2JTAG configuration to the PL and connect its I\O to the FPGA external JTAG port.

Is there a way to not waste this additional I\O pins (and had reroute the PCB, btw...)? Can a differen\multiple  debug bridge configuration allow access to the JTAG registers without external wires? Is the FUSE_DNA accessible in the undocumented 0xF800_D000 (eFuse) PS system register area?

Thank you for sheding light on the darkest, worst documented, side of the Xilinx world.

In zynq-7000 the FUSE_DNA is in the PL and not directly accessible by the PS.

I am not aware of an "easier" way to access it from the PS.
