I’m studying about the boot loader.

I aim to build the Linux kernel and boot the zImage on qemu-system-arm. First, I installed a cross-compiler for vexpress-a9. Using crosstool-ng, I installed arm-cortexa9_neon-linux-gnueabihf, but I changed the target vendor name from cortexa9_neon to hello. After building, the following executable files were created in x-tools/bin.

Next, I downloaded Linux version 6.6.33 and built it using the following commands.

make ARCH=arm CROSS_COMPILE=arm-hello-linux-uclibcgnueabihf-

I then attempted to boot using the zImage with the following qemu command. However, the outcome was as follows.

qemu-system-arm -M vexpress-a9 -m 128M -kernel zImage -nographic -append "console=ttyAMA0 root=/dev/mmcblk0 ro"

There is no progress at all. I expected the kernel to load and potentially produce a panic log, but nothing is being outputted.

Thanks for your helps!…

ps. I tried another command to build the kernel.

make ARCH=arm CROSS_COMPILE=arm-hello-linux-

But there is no output log too.
