折腾：
【记录】尝试用QEMU模拟ARM开发板去加载并运行Uboot，kernel，rootfs
期间，接着去折腾，尝试，是否可以加载自己已经在：
【记录】Ubuntu下用arm-xscale-linux-gnueabi交叉编译uboot
（【记录】Ubuntu下基于Eclipse去调用Makefile交叉编译Uboot）
编译好的uboot，并且正常运行输出。
【折腾过程】
1.参考：
先去看看mkimage的事情。
去uboot的tools下面看看
果然有个mkimage，是个x86的程序：

2.然后去做个对应的mkimage的软链接：
crifan@ubuntu:u-boot-1.1.4-whgs$ ln -sf \$PWD/tools/mkimage /usr/local/bin/mkimage ln: failed to create symbolic link ‘/usr/local/bin/mkimage’: Permission denied crifan@ubuntu:u-boot-1.1.4-whgs$ sudo ln -sf \$PWD/tools/mkimage /usr/local/bin/mkimage crifan@ubuntu:u-boot-1.1.4-whgs$ ls /usr/local/bin -lha total 8.0K drwxr-xr-x 2 root root 4.0K Aug 15 19:14 . drwxr-xr-x 10 root root 4.0K Apr 24 10:02 .. lrwxrwxrwx 1 root root 18 Aug 15 19:14 mkimage -> $PWD/tools/mkimage crifan@ubuntu:u-boot-1.1.4-whgs$ sudo ln -sf $PWD/tools/mkimage /usr/local/bin/mkimage crifan@ubuntu:u-boot-1.1.4-whgs$ ls /usr/local/bin -lha total 12K drwxr-xr-x 2 root root 4.0K Aug 15 19:14 . drwxr-xr-x 10 root root 4.0K Apr 24 10:02 .. lrwxrwxrwx 1 root root 71 Aug 15 19:14 mkimage -> /home/crifan/develop/crosscompile/uboot/u-boot-1.1.4-whgs/tools/mkimage crifan@ubuntu:u-boot-1.1.4-whgs$
3。对于教程中：
qemu-system-arm -M versatilepb -nographic -kernel u-boot
中的
versatilepb
对应的模拟的板子是：
QEMU Emulator User Documentation
中提到的：
| ARM Versatile baseboard (ARM) 。。。 The ARM Versatile baseboard is emulated with the following devices:
|
而我此处的，xscale的板子，自然的，暂时不支持。
所以，看起来，想要用QEMU去模拟我此处的pxa的板子，是没希望了。
只能是用其自带的那个versatilepb才可以。
换句话说，必须自己去下载教程中提到的，最新的u-boot-2010.09.tar.bz2，然后配置为versatilepb，然后编出个uboot，然后供此处QEMU去加载和运行。
4.下载对应的，最新的uboot：
最终得到：
u-boot-2013.07.tar.bz2
5.然后解压得到源码：
crifan@ubuntu:u-boot-2013.07$ ls u-boot u-boot-2013.07.tar.bz2 crifan@ubuntu:u-boot-2013.07$ cd u-boot/ crifan@ubuntu:u-boot$ ls api board common COPYING disk drivers examples include MAINTAINERS Makefile nand_spl post rules.mk spl tools arch boards.cfg config.mk CREDITS doc dts fs lib MAKEALL mkconfig net README snapshot.commit test crifan@ubuntu:u-boot$ pwd /home/crifan/develop/crosscompile/uboot/u-boot-2013.07/u-boot crifan@ubuntu:u-boot$
6.然后去配置和编译最新的u-boot-2013.07：
【记录】用arm-xscale-linux-gnueabi为u-boot-2013.07去配置和交叉编译versatilepb
7.重新用最新的uboot的mkimage：
crifan@ubuntu:u-boot$ sudo ln -sf $PWD/tools/mkimage /usr/local/bin/mkimage crifan@ubuntu:u-boot$ ls /usr/local/bin/ -lha total 12K drwxr-xr-x 2 root root 4.0K Aug 15 20:24 . drwxr-xr-x 10 root root 4.0K Apr 24 10:02 .. lrwxrwxrwx 1 root root 75 Aug 15 20:24 mkimage -> /home/crifan/develop/crosscompile/uboot/u-boot-2013.07/u-boot/tools/mkimage crifan@ubuntu:u-boot$
8.然后就可以去测试了：
就可以了：
crifan@ubuntu:u-boot$ ls api boards.cfg COPYING doc examples lib Makefile nand_spl README spl tools u-boot.lds arch common CREDITS drivers fs MAINTAINERS Makefile~ net rules.mk System.map u-boot u-boot.map board config.mk disk dts include MAKEALL mkconfig post snapshot.commit test u-boot.bin u-boot.srec crifan@ubuntu:u-boot$ sudo ln -sf $PWD/tools/mkimage /usr/local/bin/mkimage crifan@ubuntu:u-boot$ ls /usr/local/bin/ -lha total 12K drwxr-xr-x 2 root root 4.0K Aug 15 20:24 . drwxr-xr-x 10 root root 4.0K Apr 24 10:02 .. lrwxrwxrwx 1 root root 75 Aug 15 20:24 mkimage -> /home/crifan/develop/crosscompile/uboot/u-boot-2013.07/u-boot/tools/mkimage crifan@ubuntu:u-boot$ qemu-system-arm -M versatilepb -nographic -kernel u-boot oss: Could not initialize DAC oss: Failed to open `/dev/dsp' oss: Reason: No such file or directory oss: Could not initialize DAC oss: Failed to open `/dev/dsp' oss: Reason: No such file or directory audio: Failed to create voice `lm4549.out' U-Boot 2013.07 (Aug 15 2013 - 20:08:41) DRAM: 128 MiB WARNING: Caches not enabled Flash: 64 MiB *** Warning - bad CRC, using default environment In: serial Out: serial Err: serial Net: SMC91111-0 Warning: SMC91111-0 using MAC address from net device VersatilePB #
如图：
9.然后又去试了试基本的一些命令，输出如下：

很明显，是无法运行的，直接挂掉。
【总结】
此处，只能运行，QEMU自己的versatilepb，无法运行自己的uboot。
