Unable to Mount LittleFS File System On External Flash On NRF54L15-DK

[Khalil Tawosli]

Hi everyone,

I'm new to both nRF Connect SDK and Zephyr RTOS, and I’m trying to modify the official LittleFS FileSystem Sample to mount an external SPI flash as the storage backend.

So far, I haven't been successful in getting it to work.

I've attached the relevant files:

• .overlay file with external flash node

• prj.conf with the necessary config options

• boards/<board_name>.yaml if needed

I'd really appreciate any advice, corrections, or working examples from anyone who has managed to get LittleFS working on external flash (especially using nordic,pm-ext-flash or similar).

Thanks in advance for your help!

Best regards,
Khalil
