我在用yaffs2啓動時遇到問題fs

Question

我正在嘗試使用yaffs2 fs啓動嵌入式系統。 這是我所使用的bootargs：

控制檯= ttyO0,115200n8 androidboot.console = ttyO0 IP =關閉MEM = 256M rootwait = 1 RW根= 1f09 RW rootfstype = YAFFS2 INIT = /初始化

的我該啓動時的內核：

我也試圖與其他init腳本（/系統/ bin/sh的），但我仍然有同樣的問題。

我也tryed與ramdisk的形象和我得到這個日誌從內核：

我不這已瞭解問題的原因。 由於我對這個主題沒有很好的啓發，誰能幫我找到原因？ 是否有任何內核選項可以添加更多有關bootargs中原因或缺少細節的詳細信息？

謝謝！

嘗試在init駐留的命令行參數選項中給出根分區。例如。/dev/sda - 給出你的根分區是什麼。
