［请教］如何在skyeye上运行基于MPC8560的uboot？

phenix_yw

模拟mpc8560的skyeye配置文件应该如何写呢？在网上搜到一个，如下：
# skyeye config file sample
arch: ppc
#cpu: e500（这个是我注释掉了，根据运行skyeye的提示，好像不需要指定cpu）
mach:mpc8560
mem_bank: map=M, type=RW, addr=0xFF000000, size=0x1000000
#log: logon=0, logfile=./test.log, start=0xC0000000, end=0xB0000000

首次执行skyeye，结果如下：
[root@localhost u-boot-2009.11-rc2]# ./skyeye -e u-boot

不明白skyeye为啥需要initrd.img，先不管它，我直接把u-boot改名为initrd.img，然后再运行:
[root@localhost u-boot-2009.11-rc2]# mv u-boot initrd.img
[root@localhost u-boot-2009.11-rc2]# ./skyeye -e initrd.img

疑问：1.为啥显示的文件格式是elf-i386呢？
      2.执行run命令没有任何反应，问题出自哪？是否是配置文件有问题？

第一次使用skyeye，请大家多多帮助，谢谢～

ksh

目前还不能运行u-boot，为了直接能够运行linux，对mpc8650的处理器进行了一些相关的初始化，并不是机器一上电的标准状态。相关初始化在文件 arch/ppc/mach/mpc8560_boot_linux.c 中的mpc8560_boot_linux函数。

预计在SkyEye-1.3.1中更改这些设置可以运行u-boot，让u-boot来加载linux

晕死，那网上不是已经说u-boot运行在skyeye的mpc8560上了么，他们是怎么做？也没见他们的文章中需要改啥啊，难道是“虚假广告”了。

ksh

skyeye-1.2.3应该可以，可以参看1.2.3的release notes:
