Hi all, I’m trying to run seL as a microvisor following the CAMKES-ARM-VM. My development board is TK1-SOM from ColoradoEngineering. I was able to flash the U-boot to to load seL4 HYP mode. However when I try to load the kernel. The system just hangs. I got stuck here any help would be appreciated thank you! I built the capdl-loader-experimental-image-arm-tk1 and can copied it to the TK1 MMC storage, then I followed the wiki to setup env bootm_boot_mode to nonsec. Attachment is the printout: ------------------------------------------------------------------------------------------- U-Boot 2018.03-rc3-00090-g3990c9d (Mar 01 2018 - 14:33:40 -0500) TEGRA124 Model: Colorado Engineering TK1-SOM Board: CEI tk1-som DRAM: 2 GiB MMC: sdhci@700b0400: 1, sdhci@700b0600: 0 Loading Environment from MMC...
