USB Mass Storage Sample Application

[cagri]

Hello. I'm newbie with the NCS environment so tell me if I'm saying nosense. I use the nrf connect extension in vs code ide. (SDK: v2.7.0 toolchain: v2.7.0)

I want to create usb mass storage with spi flash on my own card so I wanted to examine the mass storage example. I copied the sample usb mass storage example with create a new application. I want to build the FAT FS Example as FLASH-based. I read README.rst but I don't understand how to do it. Can you help me with this?

Thank you.

Hello again. command line
west build -b nrf5340dk_nrf5340_cpuapp -- -DCONFIG_APP_MSC_STORAGE_FLASH_FATFS=y
But if I compile it I get errors:

Hi,

I assume you're referring to the Zephyr sample? https://docs.nordicsemi.com/bundle/ncs-2.7.0/page/zephyr/samples/subsys/usb/mass/README.html 

Thank you for providing the build logs. There are quite a few warnings here. You mention that you "want to test this on your board". What exactly is your board? Is it a nRF5340DK, or a custom board you've made with a nRF5340?

Kind regards,
Andreas

Hello,

I have a custom board with nRF52833 and W25Q512JVEIQ. I wanted to examine a similar example on a different board, because I am new to this and I don't know what to do.

Thank you for your support.

[AHaug]

Aha, thank you for clarifying.

The first issue is that you're building for the wrong target (board) if you ever want to flash the device. Your board is the nRF52833, while the build target you're building for is the nRF5340DK.

I think I would recommend you to take a few steps back from the project you're working with and instead familiarize yourself with the fundamentals and intermediate NCS courses we have on our academy pages to get to know your board and the SDK a bit better before jumping into the deep end.

You can find the course for the fundamental course here https://academy.nordicsemi.com/courses/nrf-connect-sdk-fundamentals/ 

• I recommend you do all lessons, but specially focus on lesson 1, 2 and 3

and the intermediate here https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/ 

• I recommend you do all lessons, but specially focus on lesson 1, 2 and 3

I know this is probably not the solution you were hoping for, but if you spend a day going through these two courses I believe you should be far better of and ready to pick up the challenge with getting the flash sample to work on your custom board

Kind regards,
Andreas

Actually, I just wanted to build and examine the sample. I know I can't flash it.

I looked at the tutorial you suggested and I learned that I need to type the command “west build -b adafruit_feather_nrf52840 -- -DCONFIG_APP_MSC_STORAGE_FLASH_FATFS=y” (or any other command) into the cRF Connect terminal. I was typing in powershell terminal before, so I got errors.

I wanted to mention this to help anyone who has such a problem and reads this article

Anyway, my problem is solved for now. Now I will have to analyze the sample and adapt it to myself, this is the main issue :)

Thank you
