你好~~我自已將板子上附的EXT2的ROOT SYSTEM FILE 轉成JFFS2的ROOT SYSTEM FILE 我掛到板子上面後就卡在下面的畫面

停在這就不動了~~請問是我的MTD裝置沒用好嗎~~還有VFS是什麼東東啊~~可以解說一下嗎~~還有我該怎麼做才可以把他掛到板子上面去啊~~~請各位高手教一下~~拜求~~~~

這個應該是loader的部份有問題吧, 他在跑完kernel後再到指定的ramdisk位址要讀ramdisk.gz的時候找不到了,有可能你的位址算錯了(有改過bootloader/kernel/ramdisk/mtd的大小嗎?有的話, 位址要重算一下)

[yaoyaohsu]

我沒有改bootloader/kernel/ramdisk/mtd的大小~~請問那大小要去那改啊..要怎麼改..可以教一下嗎~~~

[yasachi]

偶們家的是在kernel的flash driver裏可以設定maping的時候在那修改,您那的要看您的driver是怎麼做的..

[yaoyaohsu]

那我想問flash driver要怎麼做啊~~我沒有做過~~可以一步一步教我嗎~~~因為我用的是板子上面附的檔案~~不過他的原始檔案是ext2的格式，我只有把他kernel裡面支援jffs2的選項enable起再重新編譯起來，再來是下載一個MTD_utils_1.0.0的工具，再把ext2 mount起來，把裡面的檔案轉成jffs2，其他我就什麼也沒有動了，我用的是新華s3c2410的板子，有用過的高手可以教一下嗎！！我要再改那裡～～要怎麼改，謝謝～～
