jffs2不能写的问题

weiglink

我是先在主机上建立映像文件
mkfs.jffs2 -e 0x20000 --pad=0x1e0000 -l -d b -o jffs2.bin
然后直接把映像文件写入到flash中，启动后现在还不能进行写入，难道非要在开发板引导以后再檫除mtd分区写入映像才可以吗？没有网卡所以这样做很麻烦！
提示如下：

没人碰到这种情况吗？？？

weiglink

已经解决了；））

kuen

請問能否告訴你是怎樣解決這問題的？

謝謝

weiglink

把提示信息发来，我可以帮你看看；）

kuen

謝謝你

我是可以讀的

不過讀的時候，「len」第次都是不一樣的，而且會是一些不整齊的數 (非 256/512/1024)，而是4096, 44, 8 ，總之就不是整齊的 (間中也會出現1024)


但是寫的時候

nand_write_ecc: to = 0x00028000, len = 68
nand_write_ecc: Attempt to write not page aligned data
Write of 68 bytes at 0x00000280 failed. returned -22, retlen 221828160

不知為何「len」會是68的
我的pagesize是512，blocksize 是 16K

另外也不知為甚麼 retlen 會這麼大的，看來是overflow的問題

謝謝

sysdsn

OK!

weiglink

把整个的启动信息贴出来看看！

kuen

我的是SamSung FS44B0X ，nand flash 是 16M 的 K9F2808
nand flash 的 pagesize 應是512，blocksize 應是 16K


我都nand flash分了四份︰
Block 1 是 192K
Block 2 是 2M-192K
Block 3 是 8M-(2M) = 6M
Block 4 是 16M-(8M) = 8M

我是可以用yaffs來mount的，可以讀寫的，所以我想我的nand flash driver應沒問題的(不過不知對不對)

不過以jffs2來mount，問題就出來了，只能讀，不能寫

jffs2 的 image我是用
「mkfs.jffs2 -l --pagesize=0x200 --eraseblock=0x4000 --pad=0x30000 -d jffs2 -o jffs2.img」來製的

我把那image mount到block 1 (192K) 那裡

請各大俠幫幫忙，謝謝

weiglink

你可以在启动后，檫除jffs2分区试试！
另外nand好像要ecc的支持，具体的我不太清楚！
同时启动时有 No NAND device found!!!  提示，可能问题在这里，你可以在内核里找到这信息提示的位置，再进行分析！

weiglink

Attempt to write not page aligned data
这个错误信息也要去查查看在nand驱动的什么地方，再来分析！

weiglink

我看了一下K9F2808 的手册，你的檫除尺寸也不对啊，你再去看看！

kuen

謝謝回覆

這句「No NAND device found!!! 」應是指沒有插Smart Media Card的，因為我那個板有那個插槽。所以這句應沒關係的

我試過用eraseall，是真的可以檫除整個block

另外，我就是不明白那裡可以設定檫除尺寸的(應該說除了製造image的時候，不知道是否該在uClinux那裡設定 pagesize and earsesize的)

謝謝

weiglink

檫除尺寸是由flash的特性所决定的;
看看手册先;

kuen

謝謝

看過 http://www.samsung.com/Products/Semiconductor/Flash/NAND/128Mbit/K9F2808U0B/K9F2808U0B.htm

試過把pagesize改為 528，blocksize改為 16K+512，可是還是同一樣的錯誤訊息

mkfs.jffs2 -l --pagesize=0x200 --eraseblock=0x4000 --pad=0x30000 -d jffs2 -o jffs2.img



我不明白為何會有「Reading data from NAND FLASH without ECC is not recommended」這個錯誤訊息的
請問如來才可以啟動ECC的？

其實除了製jffs2 image的時候要設置pagesize, blocksize，要不要在uClinux 的source那裡也設置的？

謝謝
