| I tried kernel kvm-15-v10. But it seems not the kernel's problem. Because the debugger shows that the program triggers some fault in function "fdt_num_mem_rsv" of boot_loader, which leads to infinite loop. If there's no error in bootloader, it must be the device tree file that causes the problem, I guess.

I recommend you use a later branch, kvm-15-v10 for example.
The -stage branches are unflattened patches applied on top of each
other and merged with other changes, the other ones are folded down
patches, rebased on newer upstream kernels.

I have checkout the kvm-a15-v8 branch (don't know what's the difference
between kvm-a15-v8-stage branch). After recompiling the kernel, I find it
still failed to produce any output.
Later, I retried the model debugger to figure out what's wrong inside. The
problem seems to occur when loading fdt. What kind of mistake may lead to
this error?

I have disable "append device tree config option", but nothing happened
either. I guess my host NF S is not configured well, so is there any other
way to boot the host without NFS? If the kernel cannot load the file system,
will it still print out some error message to serial port?
earlyprintk should output some text even without successfully loading a file
system. Not getting any output at all means that there is a problem far too
early. You could eventually use model debugger to get a better idea on where
the problem is (bootwrapper or kernel).
Also the provided "host_config" was meant for kvm-a15-v8 branch if I am not
mistaken. Use that kernel configuration as is for the v8 branch, no need to
reconfigure with "make vexpress_defconfig".
