Hi, I am trying to use the external flash on the nRF54L15 DK with QSPI to perform the zephyr/samples/subsys/fs/fs_sample sample.
I am using NCS v3.1.0 (on Windows if that matters). I used the nrf/samples/zephyr/subsys/jesd216 and nrf/samples/zephyr/subsys/spi_flash samples to check that sQSPI communication was working properly, but I have trouble with implementing the filesystem on the external flash.
Here are the modifications I applied to the fs_sample sample :
fs_sample/boards/nrf54l15dk_nrf54l15_cpuapp.overlay

/* Because FAT FS needs at least 64kiB partition and default
* storage_partition is 36kiB for this board, we need to reorganize
* partitions to get at least 64KiB.

I also added a pm_static.yml file to put the storage partition in the external flash:
storage_partition:
address: 0x0
end_address: 0x20000
affiliation:
- disk
extra_params:
disk_cache_size: 0x10000
disk_name: SD
disk_read_only: 0x0
disk_sector_size: 0x200
region: external_flash
size: 0x20000
When I flash the sample to the board, I get the following error:
*** Booting nRF Connect SDK v3.1.0-6c6e5b32496e *** *** Using Zephyr OS v4.1.99-1612683d4010 *** [00:34:26.877,190] <err> flashdisk: Flash area 1 open error -2 [00:34:26.877,194] <err> main: Storage init ERROR!

I also tried to disable the partition manager by adding SB_CONFIG_PARTITION_MANAGER=n to sysbuild.conf. In this case, I ge the following errors:

Is this sample supported by the sQSPI peripheral ? It seems to be working when not using sQSPI.
