Re: JFFS2 directory copy problem

[Cmmn Ml <cm...@ya...>]

Hi all,

Thanks for replying on this matter. Still I couldn't solve the problem with 2.6.21-rc7 with SH7705.

I changed my system to LITTLE ENDIAN also, but the same thing happens. 

As a summary what happens is the kernel boots up fine up to the point where run_init_process("/sbin/init") is called. After the run_init_process("/sbin/init") function is called, kernel hangs itself and even the timer interrupt is not handled. As I feel the kernel fails to start a user space process and puts it self to a not running state.

According to above observation, I doubt this may be due a problem in the area where the kernel tries to start a user space process. Can it be a possibility ? If any one have used 2.6.21-rc7 on SH7705 successfully and any one can give me some thoughts, it will be a great .. great help.

By the way, I' trying to use 2.6.21-rc7 is mainly because of the JFFS2 file system problem I experienced with 2.6.16.9 kernel (in 2.6.16.9 kernel, trying to copy a directory which is larger than around 2 MB  makes the system to crash). If any one have experience that problem or have any idea about it, that will also be a help for me to sort out this problem.

Thanks

Sorry , I dont check bigendian.
I checked little endian only.
