I'm having trouble figuring out how to get the image I've created for the microZed 7020 to boot on it. It runs nicely in the qemu emulator but I can't get a valid system.bit.bin file. I've found some not quiet for microZed instructions to make a .bit.bin file, but I try using any of those files the boot process ends with a timeout on DMA when trying to load the FMGA.
For reference I'm using the Avnet-MicroZed-z7020-v2014.2.bsp file with the petalinux-create command, that appears to be the most correct one to use.

With a system.bit.bin that I made using "bootgen -image test.bif -split bin -o i BOOT.BIN" but none of the .bit files I could find to convert with that matched the instructions so I think I'm doing something wrong there. But the boot attempts with that system.bit.bin all failed with:

fpga - loadable FPGA image support
Usage:
fpga [operation type] [device number] [image address] [image size]
fpga operations:
dump [dev] Load device to memory buffer
info [dev] list known device information
load [dev] [address] [size] Load device from memory buffer
loadb [dev] [address] [size] Load device from bitstream buffer (Xilinx only)
loadmk [dev] [address] Load device generated with mkimage
For loadmk operating on FIT format uImage address must include
subimage unit name in the form of addr:<subimg_uname>

Really I'm hoping someone just points me to the correct instructions for this.
