Q1: After updating legato Framework(ex. legato-19.02.cwe), does it change only “mtd14 lefwkro”? Q2: After updating legato Application(.update), does it change only “mtd16 userapp”? Q3: Does “mtd15 swirw” equivalent to /mnt/userrw/? Back Ground: I consider the case of updating each partition. And I would like to know whether user data will be erased after updating partition. Regarding to the following ticket, it seems that user data is saved in /mnt/userrw. If Q1 to Q3 is all “Yes”, I don’t care my concern, that’s why I asked it. > [@Create directory](https://forum.legato.io/t/create-directory/2504): > > Hi, I want to create directory, but system allows me to do it, only when in my .adef file sandboxed: false.

Hi, jyijyi I tested the following procedure. (1) write legato application(.update) $update \ (2) write kernel image v19.10 fwupdate download \ (3) write kernel image v19.02 fwupdate download \ After (3), legato application is erased automatically. (Regarding to your answer, this legato application is saved in mtd16 userapp, so I think it is not erased by updating only kernel image.) Regarding to (3), I get cwe file by executing “make wp76” to the following source code.

can you try just upgrading with the same legato version on 19.2.0 instead of using 19.10.0 ? you can check by “legato version” where the string will be changed if you have upgrade successfully. ---

Hi, jyijyi > > can you try just upgrading with the same legato version on 19.2.0 instead of using 19.10.0 ? In that case, legato application is not removed automatically. I suspect if legato version is same before and after updating, legato application is kept. ---

Maybe it is because your application is not built with the new legato version. ---

Hi, jyijyi Sorry for late reply. As we tested, legato application was not removed after executing build once time. As the result, if legato framework is updated version, legato application is also needed to execute build in new legato framework. Is that right? ---

Actually I advised you to build the application together with the new legato.cwe. In this case, you don’t need to care about the above.
