Hello, I have a Samsung Exynos 5420 Arndale Octa Board and I am trying to run Xen 4.5 on it. I have successfully managed to configure and patch XEN and the kernel for the board. The problem is that XEN doesn't match the correct CPU mode for its boot.
-------------XEN early debug----------------- Starting kernel ... - UART enabled - - CPU 00000000 booting - - Xen must be entered in NS Hyp mode - - Boot failed - ------------------------------------------------------- As far as I know, the only currently working U-Boot for the octa board is a signed 2012.07 version which starts the booting CPU in a NS SVC mode. I patched it, adding all the modules needed to bring the CPU to HYP mode, as in: http://lists.denx.de/pipermail/u-boot/2013-September/163019.html However, CPU does not seem to switch properly to HYP mode, as it hangs on an assembly instruction (hvc #0) when calling the function _switch_to_hyp(), just like in: http://markmail.org/thread/dhiknm25xfbsrlo6 I am than asking you if there is something I can do to overcome this problem or if there is someone working on it who can help me out. Any help or suggestion would be greatly appreciated. Regards, F.C. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
