Please check my post about how to use the qspi on the seeed xiao ble sense. The qspi works.

Xiao BLE Sense using Mbed LittleFS on QSPI blockdevice

Hello, I am unable to mount a mbed littlefs filesystem to the Xiao BLE Sense on-board qspi flash. Urgent help needed. I am using Windows Arduino IDE 2.04, and I installed the Seeed NRF52 mbed-enabled Boards v2.9.1 through board manager. First, I checked this post about qspi demo code. https://forum.seeedstudio.com/t/xiao-ble-sense-persistent-data/262942?u=yangx30 However, the qspi demo code does not work with the above mentioned seeed library v2.9.1. I went to the lib repo and found a commit…

But the littlefs does not work with that block device. I need help. Thanks.
