nRF5340 firmware update from nRF Connect SDK ver. 2.3.0 to ver. 2.7. 0

[tommy]

I have a question regarding the firmware update for the Application core and Network core of nRF5340.
Currently, we are developing firmware using nRF connect SDK ver. 2.3.0 However, we would like to switch to nRF connect SDK ver. 2.7.0
Is it possible to update the product which burned the firmware created by nRF connect SDK ver. 2.3.0 to the firmware created by nRF connect SDK ver. 2.7.0 by using the function of Device Firmware Update (DFU) or Peripheral CPU DFU (PCD)?
My concern is whether the bootloaders in nRF connect SDK ver. 2.3.0 and nRF connect SDK ver. 2.7.0 are compatible.

Hi Tomoku,

I don't see a reason why FOTA wouldn't work to upgrade the application from v2.3.0 to v2.7.0

But you need to make sure you can update both the network core and the application core simultaneously. This is important because there can be some changes in the netcore or app core that may require that they have to be updated together. 
Please take a look here: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/app_dev/device_guides/nrf53/simultaneous_multi_image_dfu_nrf5340.html

We have a tutorial here in our Dev Academy. 

Do you have an external flash storage ? 

[tommy]

Thank you for your reply.

Also, I am sorry for my late reply.

 

As mentioned in the question, I do not use external flash storage.

 

I have just started using v2.8.0.

I am trying to check the FOTA operation using the sample program "nrf 5340_ audio" using the nRF5340 Audio DK, but the software does not start due to an error.

 

・The sample program has not been modified

・Compilation can be done using the

https://devzone.nordicsemi.com/f/nordic-q-a/116646/how-to-configure-foat-function-for-le-audio-project

as a reference.

 

It has not started due to the following error.

 

For details such as log, I will attach an excel file.

 

How can I avoid this error?

Hi Tomokuni, 

I think the issue here is that the program expecting to be able to access the external flash that you don't have. 
That's why you received: 
E: Failed to open flash area ID 2 (image 0 slot 1): -19, cannot continue

The reason for that is that there will not be enough free space to receive image to the internal flash. So an external flash is needed. This is mentioned in the ticket you pointed to: https://devzone.nordicsemi.com/f/nordic-q-a/116646/how-to-configure-foat-function-for-le-audio-project

Hung, thank you for your reply.

I would like to know two things: how to avoid accessing external flash and how to reduce the firmware size to perform FOTA without using external flash.
Since we have just compiled the sample program provided by Nordic as it is.

Hi Tomokuni, 

Which firmware are you compiling ? If you are doing the audio firmware, it's not possible to do DFU update without external flash if you plan to update both network core and application core. 

Please take a look here: https://docs.nordicsemi.com/bundle/ncs-2.5.1/page/nrf/applications/nrf5340_audio/README.html#nrf53-audio-app-configuration-configure-fota
