Dear users,

do you know if it is possible to clone content of WP76xx module and flash it on other module? I’m trying to replicate SW issue that occurs in the team in other city.  
If I would run x86 Linux I’d run good-old `dd` command and get everything cloned, but I guess WP76xx platform offers more advanced way of doing this.

Regards,  
Aleksandar

OK I just have learned that my WP7607-1 has 21 partitions 😯

```
# cat /proc/mtd

mtd19: 02180000 00040000 "slot_1"
mtd20: 02180000 00040000 "slot_0"

```

which is different from 5 partitions showed [here](https://source.sierrawireless.com/~/media/developer%20zone/content/legato/wp%20flash%20mapping.ashx?la=en) or 7 from [here](https://forum.legato.io/t/larger-rootfs-wp8548/2012)  
Is there some description (at least read-me txt file) to understand which partitions are changed during runtime (e.g. where is ConfigTree data stored etc)?  
To note, I just need to take a snapshot of writable part of the system so I can clone it easily.

Hi @aleksandar.zivkovic ,  
ConfigTree data will be storesd in the USER1/MTD4 partition where the application are stored, So i think USER1/MTD4 partition will get changed during runtime. Will let we you know if we come across any further information on this.

Thanks for answer,

Hi @aleksandar.zivkovic,  
Sorry one clarification here, In **WP85** legato applications, config tree will be stored in **user1/mtd4** partition, Which is read write partition and totally WP85 has 7 partitions.

Similarly in **WP76** , legato applications, config tree will be stored in **userapp/mtd16** partition (mtd16: 08300000 00040000 “userapp”), Which is also a read write partition and totally WP76 has 21 partitions as you told.

Hope it is clear now.
