Uploading files using the filesystem module with MCUMGR

[Vitalacy Guy]

I'm trying to upload image asset binary files onto a custom hw that uses the nrf52833 mcu. I use mcumgr for performing DFUs and I would like to use it to upload the binary files which is outlined here:

docs.zephyrproject.org/.../mcumgr.html

Unfortunately when I try to perform a upload I get back an error code 8 which according to the MCUMGR sdk file mgmt.h signifies that the operation i attempted is not supported. What do I need to configure to make uploading files via MCUMGR possible? I uploaded my conf files, let me know if you have any questions.

 release_devzone.confprj_devzone.conf

So during tuning my project's kconfig settings I found out that by increasing the value of 

CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE

it fixed the usage fault. For anyone else that is having the same issue uploading files using mcumgr fs, try modifying this setting.
