[meta-xilinx] rel-v2018.1 / zcu102-zynqmp: U-boot crashes with error "fdt_root: FDT_ERR_BADMAGIC"

[Martin Lund]

Hi Manju,


Ok, I've updated u-boot-mkimage to use the 2018.1 recipe from meta-petalinux by copying the files to the meta-xilinx layer.


Then when building arm-trusted-firmware it triggered a rebuild to update u-boot-mkimage which resulted in an updated atf-uboot.ub. I notice that u-boot-xlnx does not depend on u-boot-mkimage.


However, it did not solve the issue - I still see the following error:

Resetting CPU ...

### ERROR ### Please RESET the board ###


Any ideas what else might be broken?



FYI - on a similar note, I've pushed a patch upstream to update the README.booting.md in meta-xilinx to include updated SD install steps for ZynqMP:

https://lists.yoctoproject.org/pipermail/meta-xilinx/2018-May/003793.html


Those are the install steps we are following and expected to work for meta-xilinx after building core-image-minimal.


Thanks.

Hi Martin,

Can you update the u-boot-mkimage recipe as well?
https://github.com/Xilinx/meta-petalinux/blob/master/recipes-bsp/u-boot/u-boot-mkimage_2018.01.bb

An give it a shot?

We use the entire layer stack during testing meta-petalinux,meta-xilinx and meta-xilinx-tools and did not see this breakage

Thanks,
Manju
