Issue Accessing External NoR Flash when BLE is Enabled in Zephyr with nRFConnect in VSCode

[Sameera]

Hi,

I am using nRF5340 dev kit. I have successfully accessed external NoR flash (mx25r64) over qspi. But once I enable BLE with setting 'CONFIG_BT=y', I got littlefs mounting error as follows:



My prj.conf:

# General configurations

I have even not enabled BLE functionality when this error occurs using this function :

    err = bt_enable(NULL);

I am using VSCode as the IDE and following versions:

SDK : v2.6.1
toolchain: v2.6.1

Note:
I earlier used the version 2.6.0 for both SDK and toolchain and the error was same. Then I switched to the latest.
