Works for me with: $ qemu-system-arm --version QEMU emulator version 3.0.0 Copyright (c) 2003-2017 Fabrice Bellard and the QEMU Project developers => bootefi hello Scanning disks on mmc... MMC Device 1 not found MMC Device 2 not found MMC Device 3 not found Found 3 disks WARNING: booting without device tree ## Starting EFI application at a0008000 ... WARNING: using memory device/image path, this may confuse some payloads! Hello, world! Running on UEFI 2.7 Have SMBIOS table Load options: <none> ## Application terminated, r = 0 That is with CONFIG_CMD_BOOTEFI_HELLO=y added to the vexpress_ca15_tc2_defconfig of course. > Bisection points to > efi_loader: ARM: run EFI payloads non-secure > commit dc500c369486fbe04000fd325c46bb309e4a1827 That suggests an issue with emulation if the mode switching instructions or HYP support in qemu. Or a toolchain issue of course. Cheers, Mark _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
