Re: Xen 4.14.1 on RPI4: device tree generation failed

Hi Tamas,

I had another problem with device tree built with this script (rpixen.sh)...

No promises, but it's worth trying on clean tree:
make O=.build-arm64 ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j $(nproc) dtbs
(instead of broadcom/${DTBFILE})

Good luck,
