Hello,everybody: I have porting linux2.6.11.8 on the ARM s3c2410 using the yaffs as root filesystem. And it runs well but: 1. If I "mkdir gg", it shows me the message:"mkdir: Cannot create directory `gg': Cannot allocate memory". When I disable the ECC, the question also appears. 2. The root device was created using linux2.4 before(done by somebody else), also as yaffs. It has no problem when using the linux2.4. 3. When tracing "mkdir", I found that the return value of the function "yaffs_AllocateChunk" is < 0. Does somebody meet these questions? Please give me some suggestions. what i do to port the linux2.6.11.8 is the same as this article describes:http://superlp.blogchina.com/1391393.html -- USTC Alumni Email System
