[meta-xilinx] Cannot load VFS from SDCard partitioned using wic

[Giordon Stark]

Hi all, I'm using a zynqmp 102 chip:

I used the wic file created to flash an SD card using dd. I also copied
system.dtb and created a BOOT.bin to copy into the first (boot) partition.
However, the SD card seems readable, and shows the right partitions.. but I
still cannot get the kernel to load the FS from it?

Any ideas?
