Anna, Sure - I've tried a few different combinations, but the latest Genode 18.5 used seL4 9.0.1. I'm attempting to use this on an x86 machine that has a Xeon 1607 and a dedicated GPU. The thread I referenced in my initial post implied that UEFI might be an issue, but I've tried both UEFI and legacy boots without success. I tried using/building Genode 17.5 with whatever version of seL4 it acquires, but get the same error. Let me know if there's anything else I can provide On Wed, Jul 4, 2018 at 7:51 PM wrote:

Hi Jeremy,

Could you please provide more details about your setup? What version of seL4 are you using? And which platform / configuration?

Thanks

Anna.

Hello-

I'm trying to boot Genode/seL4 on hardware. I've tried a few different combinations of versions, and GRUB configurations, without success. I keep getting the same error despite these different combinations

There was a thread that touched on this, but I couldn't find any resolution http://sel4.systems/pipermail/devel/2017-December/001776.html

Any thoughts? Anything I can try? Any information I can provide to help diagnose?
