ff.h no such file or directory

[Ben_Squar3d]

Hi, 

I am working with nRF5340 and nRF Connect v2.7.0. When I try the mass sample it works fine. When I take the code to my custom project, I have 

ff.h no such file or directory

I have seen other threads that speak of the issue and the fact that there are issue witrh out of tree build, but I didn't found any solution to this. I assume it is because the files containing the code are not sourced to app directly, but linked like this : 

zephyr_link_libraries(MassStorageLib)

The MassStorageLib contain the files mass_storage.c and mass_storage.h that are mostly inspired by the working sample. 

How can I make it work ? As a subsidiary question, is it the recommended way to make a mass storage out of the nRf5340? 

Thank you for your help

Hello,

I spoke to Vidar yesterday, who is handling your other ticket. It seems like this was pretty much the same question as your last question here. Please let me know if you still have some unanswered questions here, after checking out Vidar's reply.

Hi, my declaration of the partition was wrong, and I wasn't using sysbuild. I don't build with my app yet, but now I have a working example of fs+ble+mcuboot. Thank you both for your help!
