Re: JFFS2 questions with eCos
Hi Andrew,
I find that there is the FSTAB_ENTRY as following if I turn on the
CYGOPT_FS_JFFS2_WRITE :
FSTAB_ENTRY(jffs2_fste, "jffs2", 0,
CYG_SYNCMODE_FILE_FILESYSTEM | CYG_SYNCMODE_IO_FILESYSTEM,
jffs2_mount,
jffs2_umount,
jffs2_open,
jffs2_ops_unlink,
jffs2_ops_mkdir,
jffs2_ops_rmdir,
jffs2_ops_rename,
jffs2_ops_link,
jffs2_opendir,
jffs2_chdir, jffs2_stat, jffs2_getinfo, jffs2_setinfo);
Question :
Q1 :There are the functions to write the jffs2 filesystem,
but currently RedBoot does not support the commands.
So we can not write (create) a file/dir into the jffs2 image.
Is it correct ??
Q2 : It is the same with FAT filesystem as JFFS2 filesystem,
currentky it does not support the write command.
Is it correct ??
Q3: If I add the some commands likes open (create) by using above functions,
then I can create a file into jffs2 filesystem.
Is it correct ??
Thank you~~
Steven Cheng
