tests/subsys/fs/fcb fails on nRF52840-DK

[mbolivar-nordic]

Describe the bug

I'm getting a test failure on tests/subsys/fs/fcb for nrf52840dk_nrf52840.

To Reproduce
Steps to reproduce the behavior:

1. cd zephyrproject/zephyr
2. west build -b nrf52840dk_nrf52840 -p -t flash -s tests/subsys/fs/fcb
3. test fails on device serial console

Expected behavior

The board is listed in platform_whitelist inside tests/subsys/fs/fcb/testcase.yaml, so I expected this to pass.

Impact

Unclear.

@nvlsianpu not sure if you are the right assignee. Please feel free to change.

@nvlsianpu should we deprecate FCB at this point?

Ah, so this is the one which might get deprecated. I couldn't remember the status of all these storage backends.

Not today - we can deprecate fcb at some point, but it was not problematic for user and initially it was the default setting back-end, so better to make a query before.
