然後就停在這裡沒動作了....
請問是為什麼呢??
ext2fs.gz是根據這各網站http://www.jollen.org/blog/2007/01/arm9_bootstrap_root_filesystem.html 自己做的filesystem
請各位大大幫幫忙><

Jollen網頁最下面有提到
jollen.org # tftpboot 32000000 urootfs.img; tftpboot 30F00000 uimage.img; bootm 30F00000 32000000

看出來你少了什麼嗎？No init found就是說你的rootfs沒掛成功
先用mkimage -A arm -O linux -T ramdisk -C把你的ext2fs.gz 包裝成 U-Boot 的格式後

再把
#bootm 0x20000000
改成
#bootm 0x20000000 0x21100000吧

註：mkimage 可以在uboot的source file目錄中找到 (tools/mkimage)
