Sorry ,what does means plain text ?
 
You are emailing html intead of text. Some Windowsy client I guess. Note the blue text and vertical blue bars. I have seen exchange server seem to add html as a wrapper. There is a move to bounce all html emails by zealots.
 
>what does /proc/yaffs say?
 
this is the output of my /proc/yaffs
 
# cat /proc/yaffs

>How big is the mtd partition in the boot messages?
 
# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 04000000 00004000 "BON"
mtd1: 021fc000 00004000 "mtd"
 
2 mtd blocks. Are both yaffs? I am not clear which block /proc/yaffs is referring to but it looks like /mtdblock/1 as 21fc000 bytes is 2175 16k blocks. Is there data in the nand partition? Is it sane?
 
I have seem this before on systems which had a mismatch in the ecc encoding or which had had a lot of erase/resumes.
My problem was a mismatch in the ecc calculations used to write the yaffs image (using bootldr) to nans and that used by linux. Reading was fine, writing was a mess.
 
You could enable mtd debugging and it should tell you where it finds pain.
 
 
    Thanks

Could you use plain text? It makes replying much easier.
 
what does /proc/yaffs say?
If its all used it may be that it isn't all erased ot being accessed correctly.
How big is the mtd partition in the boot messages?

Hi ,

I am using an ARM machine with 2.4.18 kernel
I want to use yaffs , the file system is mounted , but when I try to do any operation , as mkdir or cp , I get the message

"cannot allocate memory" and the command df says 100% used for /dev/mtdblock/1

Any help will be appreciated
