I don't know whether that command does any check to say it has been written correctly, but if it does this means your PL is powered up. > I also added some LED output to my fabric design to see if it comes up > after programming, Good idea. > and the LEDs fail to light up… Which leads me to > question what is responsible for powering up the PL island? I don't remember having ever written a single line of code to power it up. I guess it's done by the psu_init code... Try to validate your FPGA design by sending it directly from Vivado to the board via USB. No U-Boot, no Linux, no software at all. Does the LED light up that way? -- Luca -- _______________________________________________ meta-xilinx mailing list meta-xilinx@yoctoproject.org https://lists.yoctoproject.org/listinfo/meta-xilinx
