LittleFS config creating un-used partition in flash_primary

[Brett_G]

I am using LittleFS for an external NAND flash by using the KCONFIG option CONFIG_FILE_SYSTEM_LITTLEFS=y and managing the driver implementation manually. This has worked well for me, but I have found that this config option seems to also create an un-used partition on the internal flash_primary shown below:

I assume, since the implementation of littleFS is on external flash, that this is not being used for anything.

I had plans to use some of that flash for an NVS implementation, but having the random partition in the middle of everything complicates it a bit.

Is that partition being used for anything internally? or is there a way to enable use of littleFS without allocating a partition in flash_primary?

Thanks,

No problem. It is worth mentioning that  there are a lot of open issues with how littlefs interacts with NAND. It really is not designed for it, and there are a lot of speed and size inefficiencies, that can only partially be worked around.
