Any news here?

As described, i already did that - encountered this problem and isolated it to just enabling the defines. I have retried and i can init SD card and mount FS.

However i debugged it a little further (in the scenario where my SDCARD is initialised and mounted)The problem arises when FS is enabled together with CONFIG_BT_SETTINGS

So:

CONFIG_BT_SETTINGS=y

CONFIG_SETTINGS=y

and:

CONFIG_DISK_ACCESS=y

CONFIG_FILE_SYSTEM=y

CONFIG_FAT_FILESYSTEM_ELM=y

Then the following chain of events plays out:

bt_settings_init()
settings_subssy_init()
settings_store_init()
settings_backend_init(void) (in zephyr/subsys/settings/src/settings_file.c)
settings_mount_file_backend()
mkdir_if_not_exists()
fs_mkdir() returns -2

This apparently works when FS configs are not set.

Maybe you could have a look at how it's done in this fs_sample ? There are overlays' and config's for the nRF52840, so you might need to create some for the nRF5340.

Hi, did you have a chance to take a look at it?

Hi!

What version of nRF Connect SDK(NCS) are you using?
