nrf5340_audio app build fails when selecting external flash

[khett-ptd]

I am using ncs v2.2.0 on Windows.

Using the python buildprog.py script I am able to build and run the nrf5340_audio application with the bootloader enabled and using the internal flash memory.

Here is the build command that builds and runs correctly:

C:\ncs\v2.2.0\nrf\applications\nrf5340_audio>python .\tools\buildprog\buildprog.py -c both --pristine -b release -d gateway -m internal

If I then build using the external flash memory option using the following command, the build fails:

C:\ncs\v2.2.0\nrf\applications\nrf5340_audio>python .\tools\buildprog\buildprog.py -c both --pristine -b release -d gateway -m external

Here is the output from the build process:

Is the use of external flash a supported option when using ncs v2.2.0? 

If so, can give me some guidance on how to resolve this build issue?

Thanks,

Hello Kristopher,

I do not think the current audio DK has external flash. You could get an external flash device and wire it to the DK though.

I understand this can be confusing considering the references to external flash in some of the documentation, for an explaination of that, see here.

Regards,

Elfving

Hi Elfving,

I have attached an external SPI flash memory to the nrf5340 audio dev kit and now I am trying to get the application compiled so it will interact with the external memory.  The issue here is that audio app does not build if I compile with the switch that selects the external memory.

I have been doing some more debugging and I discovered that the script "\ncs\v2.2.0\zephyr\zephyr-env.cmd" sets the variable ZEPHYR_BASE to "c:\ncs\v2.2.0\zephyr\.  I noticed in the build output that some of the paths looked suspicious so I changed the value of ZEPHYR_BASE to be "c:/ncs/v2.2.0/zephyr/" and now I can build the audio application with the external memory option.

Is there another env var configuration script that should be used to set the env vars when using ncs on a Window machine?

Thanks,
-- Kristopher

[Elfving]

Hello again Kristopher, and sorry about the wait.

Great that you have in a way found the problem. You could set the enviroment variables ZEPHYR_BASE and toolchain using the script that you can find within the {NCS version}/zephyr/ folder. You could also alternatively run the cmd from the toolchain manager using the drop down menu next to the NCS version you're using.

I believe this issue stems from where your application is placed in relation to the SDK. Do you have a freestanding application?

Regards,

Elfving

Hi Elfving,

This build issue happens when I try to build the nrf5340_audio application in the ncs directory.  On my system ncs is installed on the C: drive and the app I am trying to build is in the following directory:

C:\ncs\v2.2.0\nrf\applications\nrf5340_audio\tools\buildprog\buildprog.py

I am trying make sure that I have the ncs SDK and build systems installed and configured correctly on my PC.

Can you verify that you are able to build the nrf5340_audio application with the external DFU memory option builds on one of your windows PC systems?

Thanks,
-- Kristopher

Hi Elfving,

I also encountered the same problem in NCS2.2.0.
