Hi Matthew,
I had have some similar issues with the microzed. Nevertheless in reality you need to create your own FSBL and bitstream for your application. So you could try to create a fsbl for your board. Please keep in mind that the fsbl contains the ps7_init.c, what initializes most of the Zynq (MIO, Clocks, PLL's, ...). Use bootgen to build your own boot.bin comprising fsbl, bitstream (build by vivado) and u-boot.elf (build by bitbake).
The fsbl and bitstream used by yocto are only templates and need to be replaced anyway for your application.
That works for microzed and zedboard.
Hope that helps,
Martin

Hi,
I've had some experience with Yocto in the past and I'm trying to get a project started using the Avnet Zedboard, I have YP fido 1.8 and the meta-xilinx setup. I had an issue with a recipe downloading source initially and now have a successful core-image-minimal build. Initially I am trying to boot directly from the SD card and the boot process appears to hang up when reading the kernel.
Boot Sequence output:
U-Boot SPL 2015.01 (Oct 28 2015 - 09:53:12)
mmc boot

Source Download issue (could be related?)
Problem downloading "git://github.com/Xilinx/embeddedsw.git;protocol=https;branch=master" in fsbl-platform-init_2014.4.bb
It could not find the source. I manually downloaded the source and placed it in the appropriate folder "<builddir>/zedboard_zynq7-poky-linux-gnueabi/fsbl-platform-init/2014.4-r0/git" to get past the issue after trying several times to resolve it.
Thanks for your help.
