Hi there. I'm having some issues with the results of the Zynq-Linux Lab 2.2, when I try to boot the ZedBoard. I consistently get the following error message out of u-boot:
Wrong Ramdisk Image Format
Ramdisk image is corrupt or invalid
I followed the procedure outlined in 2.2. I've even tried loading u-boot with both the uncompressed ramdisk and the gzip'ed version. Same message.
In the interest of full disclosure, I am using the 14.7 toolchain, and as such, I checked out the xilinx-14.7 tag of u-boot. I did the correct configure, and had no build errors. So I'm not certain why this issue would come up. I can mount the uncompressed ramdisk image just find in openSUSE, so I don't really think it is an ext2 format issue.
Have any of you guys done the same lab procedure using the 14.7 toolchain, and been able to create a boot SD card boot set?
I've also tried manually using the u-boot "fatload" commands to load the file into memory, as I thought maybe the mem offsets used by default in uboot would mess thing up. The fatloads worked fine - but no matter what, the bootz or bootm is what would fail. Here is what I normally try:
zynq-uboot> fatload mmc 0 0x80000 zImage
reading zImage
3083112 bytes read in 277 ms (10.6 MiB/s)
zynq-uboot> fatload mmc 0 0x1A00000 devicetree.dtb

Thoughts?
