U-boot hyp mode

Postby tklengyel » Wed Mar 30, 2016 3:41 am

Hi all,
I'm trying to get Xen to run on the Arndale Octa but unfortunately the u-boot build that's available doesn't start in NS Hyp mode. I'm trying to port the U-boot patches from the ODROID-XU that has smdk5410 CPU, so technically very similar to what the Octa has. I've applied the same patches that got the XU to boot in the correct mode to the Octa (available at https://github.com/tklengyel/u-boot/tre ... 12.07-virt). However, when I flash the resulting bl2 blob from spl/smdk5420-spl.bin and the u-boot.bin the board doesn't boot at all. I assume the bl2 blob needs to be signed? If so, any chance to get it signed (it's attached in the zip)?

Thanks,
Tamas
