[meta-xilinx] u-boot fpga command silently fails on zcu102 SD boot

[Monaghan, Michael L. (GSFC-5870)]

Hello all,

When booting from SD on the zcu102, the u-boot `fpga` command appears silently fails to configure the PL. The done led does not illuminate and the command returns 1.

Everything was built on the thud branch.

Here's a console snippet from u-boot to help illustrate the problem. I appended a full log starting from power on to the end of this email for additional reference.

Not sure if its related, but I am building the PMU firmware from meta-xilinx using the "zynqmp-pmu" machine as detailed here https://github.com/Xilinx/meta-xilinx/blob/thud/meta-xilinx-bsp/README.building.md. I have also applied the PMU firmware patch mentioned in the readme to load the XPm_ConfigObject at boot https://github.com/lucaceresoli/zynqmp-pmufw-builder/blob/master/0001-Load-XPm_ConfigObject-at-boot.patch.

Any ideas?

Thanks,
Michael Monaghan
