本帖最后由 huliqun138 于 2012-10-16 08:30 编辑linux内核是2.6.28用的arm-linux-gcc 3.4.1 编译
文件系统busybox 1.13.3用的arm-linux-gcc 4.3.2编译 ，我试过用一般的编译版本的编译器没用，
烧录后上电启动打印的信息，真心看不懂，求救啊，搞了几天了
网上找资料，有帖子说a,b 方法有效，但我都式了，根本没用
a. 重新配置内核，选上以下参数：
Kernel Features --->
[*] Use the ARM EABI to compile the kernel
[*] Allow old ABI binaries to run with this kernel (EXPERIMENTA)
b. 把编译器换成3.*。
我当然会选择第二种了，于是乎又把编译器换回3.4.1版本。再次重重新编译下载启动，从终端的启动信息可以看到。2.6.33.7内核+yaffs2文件系统顺利启

自己移植的内核或运营商的内核 +自己移植的文件系统就会打印错误信息，
自己移植的内核或运营商的内核 +运营商的文件系统就能正常启动，
那应该是文件系统的问题吧，但我前后反复检查了10几次了，真心找不出是哪的问题
