Hi,

I am trying to build U-Boot for an Avnet MicroZed board with a Zynq7 processor. Needing a customized hardware initialization, I tried to replace the distributed 'board/xilinx/zynq/MicroZed_hw_platform/ps7_init_gpl.[hc]' files with the ones produced by the Xilinx tools during creation of the FPGA design. A PetaLinux system built using the hardware description from which I took these files runs just fine, so I am as sure as can be that they are o.k. However, the 'boot.bin' SPL program thus built gets stuck early during the boot process, before any console output is produced. One of the LEDs on the RJ45 jack is flashing. If I repeat the build using the distributed ps7_init_gpl files, everything is fine.

I had expected that I could simply replace the distributed ps7_init_gpl files with the ones from the actual FPGA design, but this does not seem to be the case. Is there anything I am missing?
