Hi, I tried to build aarch64 image by follow https://en.opensuse.org/openSUSE:AArch64#Boot-wraper. 1. However seems some steps maybe missed before "Cross-compile *.axf file", I guess the following steps should be run under boot-wrapper-aarch64 folder, is my understanding correct? $ autoreconf -i $ ./configure --host=<toolchain-triplet> --with-kernel-dir=<kernel-dir> <other-options> 2. I used below cmds to compile boot-wrapper-aarch64 1) ./configure --host=aarch64-linux-gnu --with-kernel-dir=<kernel-dir> --with-dtb=<kernel-dir>/arch/arm64/boot/vexpress-foundation-v8.dtb Boot wrapper configuration ========================== Linux kernel build dir: /home/gjiang/linaro-aarch64/ Device tree blob: /home/gjiang/linaro-aarch64/arch/arm64/boot/vexpress-foundation-v8.dtb Linux kernel command line: console=ttyAMA0 earlyprintk=pl011,0x1c090000 Embedded initrd: NONE Use PSCI? no CPU IDs: 0x0,0x1,0x2,0x3 Use GICv3? no 2) make CROSS_COMPILE=aarch64-linux-gnu- BOOTARGS='"root=/dev/vda2 consolelog=9 rw console=ttyAMA0"' FDT_SRC=vexpress-foundation-v8.dts IMAGE=linux-system-foundation.axf gic.S: Assembler messages: gic.S:26: Error: invalid address at operand 2 -- `ldr x1,=' gic.S:42: Error: invalid address at operand 2 -- `ldr x1,=' make: *** [gic.o] Error 1 But apparently some errs happened due to can't find the addrs for GIC_DIST_BASE and GIC_CPU_BASE, and I do following changes to fix it. diff --git a/arch/arm64/boot/dts/vexpress-foundation-v8.dts b/arch/arm64/boot/dts/vexp index 5e566a7..23e8e95 100644 --- a/arch/arm64/boot/dts/vexpress-foundation-v8.dts +++ b/arch/arm64/boot/dts/vexpress-foundation-v8.dts @@ -64,7 +64,7 @@ }; gic: interrupt-controller@2c001000 { - compatible = "arm,cortex-a9-gic"; + compatible = "arm,cortex-a15-gic"; #interrupt-cells = <3>; #address-cells = <0>; interrupt-controller; 3.
