[U-Boot] Using u-boot with qemu-system-mips(qemu-2.1.2) caused infinite loop
Hello all: I just downloaded the latest u-boot source code,then compiled with: make qemu_mips_defconfig make CROSS_COMPILE=mips-linux-uclibc- then create image: # dd of=flash bs=1k count=4k if=/dev/zero # dd of=flash bs=1k conv=notrunc if=u-boot.bin
run with: qemu-system-mips -M mips -pflash flash -nographic
but I got nothing then I try to debug with gdb,I got this:
0xbfc001fc <_start+508>: nop 0xbfc00200 <_start+512>: b 0xbfc00200 <_start+512> 0xbfc00204 <_start+516>: nop 0xbfc00208 <_start+520>: nop
Another thing, the file u-boot.bin I got was 215k, is that ok?
What should I do to use u-boot in qemu?:)

with recent Qemu versions there occurs a CPU exception in CFI probing

if you don't need 64bit support, you should use the malta board for Qemu
$ make malta_defconfig $ make CROSS_COMPILE=mips-linux-uclibc- $ qemu-system-mips -M malta -m 256 -nographic -bios u-boot.bin

Dear Daniel: Thanks for your guide,It's really helpful.Then last question,which version of qemu do you use?:) 在 2014/12/5 22:14, Daniel Schwierzeck 写道:
