Hello, we are having a problem that only seems to appears with new devices from our factory.

 

yaffs_lstat will return -1, aka file doesn’t exist.

 

Steps:

  1. Initial power-up we default our configuration files.
    1. We have multiply mount points but it appears to happen only on the first mount point. Blocks 1-32
  2. Reboot and files all exist in fist mount point. (yaffs_lstat returns 0)
  3. Do a write to a file in first mount point
    1. Any file (from what I can tell)
  4. Reboot and all files don’t exist (yaffs_lstat returns -1)
  5. From then on any write and reboot the files will exist.
    1. I haven’t been able to reproduce it after this.

 

FYI flash NAND is a micron MT29F1G08ABADA.

 

Has anyone seen such behavior?

 

Any help is appreciated.

 

Regards,
