Hello,

I've been trying to compile U-boot for hi-tech global's HTG-Z920 board. It's SoC is the zynq ZU19EG ultrascale+. I'm mainly confused as to how I should configure Kbuild with the bare necessities -- UART, SD-LS, and DDR. I've managed to get things running via an FSBL generated with the xilinx sdk (ver. 2018.2), so I know it should be possible. Currently, I only receive the FSBL boot messages, even after enabling the early debug UART. I tried to match the addresses given by my hardware definition file (.hdf), but nothing's appearing.

Should I try adapting one of the pre-set boards' configs (e.g. for the zcu104?), or are there some major pieces I'd still need? I also have the device tree derived from the .hdf file. Would it be simpler to use that?

Any help you can spare would be greatly appreciated!

Thanks in advance, -Patrick
