问个嵌入式问题:关于U-BOOT启动内核

xw009

zImage在用vivi启动时是没问题的

xw009

若用uimage,下载到30000000,则:

到这里不动了

文件系统呢？

xw009

还没加载，这样应该说明kernel有问题了吧？

试一试
tftp #地址1 zImage
tftp #地址2 ramdisk.image.gz
go 地址1
这样应该就没有问题了

游行到此

这个问题, 我正在困惑呢
我怀疑是地址映射的有问题.
因为制作image文件时, load address 和 entry address选择的不同, 现象也不同.
但是我还是没有用u-boot启动成功

xw009

好象是内核分区与bootloader分区不一致吧

Data Size: 626188 Bytes = 611.5 kB
Load Address: 30008000
Entry Point: 30008000
好像你的加载有问题。611KB的image在30000000处，肯定覆盖到30008000了吧。
然后解压缩到30008000会不会把原来压缩的image覆盖？

把你的ld.script发出来看看
