Hello All,
It's really disappointing that we can't get a quick response in yaffs mail group.
This issue blocked me several weeks and we can't find any update in yaffs repository.
What's more, many developers think there is something wrong in the mkyaffs2image.
Usually, during linux booting, we get the following warning which is related with this tool.
For example:
s3c-rtc s3c2410-rtc: setting system clock to 2000-01-01 02:27:02 UTC (946693622)
yaffs: dev is 32505858 name is "mtdblock2" rw
yaffs: passed flags ""
VFS: Mounted root (yaffs2 filesystem) on device 31:2.
Freeing init memory: 136K
Failed to execute /linuxrc. Attempting defaults...
Kernel panic - not syncing: No init found. Try passing init= option to kernel. See Linux
Documentation/init.txt for guidance.
[<c0019960>] (unwind_backtrace+0x0/0xf0) from [<c03344e8>] (panic+0x58/0x18c)
[<c03344e8>] (panic+0x58/0x18c) from [<c00085c4>] (init_post+0x7c/0xcc)
[<c00085c4>] (init_post+0x7c/0xcc) from [<c0452838>] (kernel_init+0xe4/0x114)
Then I trace the error information in fs/exec.c, in function do_execve_common, there is wrong file ponter(IS_ERR). In NFS mode, I mount the yaffs2 block to mnt directory, and there is only lost+found folders, all other folders can't displayed. So, it's quite possible that this tool generate a wrong yaffs2 image in the former version. And the latest version can' compile.
Could anyone help me? Sometime I want abandon the yaffs FS, because UBIFS works very well every time.
We need to do too much work to make the latest yaffs work well in the latest linux kernel.

1450 struct user_arg_ptr envp,
1451 struct pt_regs *regs)
1495 file = open_exec(filename);
1496 retval = PTR_ERR(file);
1497 if (IS_ERR(file))
1498 goto out_unmark;
