cd等常用命令用不了
康老师ksh和各位好:我在Ubuntu 10.04.4 LTS中下载了skyeye-1-3-1_rc1.tar.gz，能够编译成功，最后在/opt/skyeye/下生成了新的skyeye。
然后，有下载了skyeye-testsuite-1-3-1.tar.gz，解压后，到skyeye-testsuite-1-3-1/uClinux/at91/uclinux_cs8900a目录下，
运行：/opt/skyeye/bin/skyeye -e linux，然后执行start-run，能够出现uclinux的标识，但是当我在
Sash command shell (version 1.1.1)
/>
下，运行：cd bin，
出现：(running)cd: No such command for skyeye.
请康老师ksh和各位给解释一下，是什么问题？
并且：
在start后，会有
not load section .bss: addr = 0x010f6440size = 0x000222c0 .
出现，这个是不是也有问题？
skyeye.conf内容如下：
-------------------------------------------

运行结果如下：

[ 本帖最后由 cnlihao 于 2012-10-24 12:58 编辑 ] 刚才的效果不好，重新编辑了 问题换了一种方式解决了，我主要想试一下skyeye运行自己的写的程序有没有问题，
照网上的hello例子编译成功一个可执行文件，然后，将romfs.img文件解压后，
重新复制到新的目录下，将hello复制到bin下后，修改etc/rc文件，加入/bin/hello，
然后使用genromfs，重新生成romfs.img，然后，重新运行skyeye，在输出结果
中有Hello运行的结果了。
在启动完成的命令行中，不能运行一些系统命令，我想可能是有些环境变量的问题，但是，
大部分功能应该是可以用了。
由于本论坛人气不是很旺，我想把我的一些心得写出来，供大家参考。 需要加一个-n的参数，来禁止SkyEye本身的命令行功能。如下：
/opt/skyeye/bin/skyeye -n -e linux
