Getting CMake-Error when adding CONFIG_BUILD_S1_VARIANT=y

[Ryisen]

So I am using an nRF5340DK with the "central-bas" example project. I added the MCUBoot-Bootloader by adding "CONFIG_BOOTLOADER_MCUBOOT=y" to the prj.conf file and it works, I get output from the application core.

Now I wanted to build a second version of this firmware for slot 1, but if I add "CONFIG_BUILD_S1_VARIANT=y" to the prj.conf file, I get:

Any ideas, how to fix this issue?

Hi Alex,

You are getting some errors because of cache. Can you try rerunning CMake, or deleting the build folder completely and configuring the project again?

Best regards,

Marte

[Ryisen]

Well, it did something.

I deleted my build folder completely and tried to reload the project "central-bas", but now I get:

error: cmake failed

This didn't happen when I built the application without "CONFIG_BUILD_S1_VARIANT".

How do I solve this?

Best regards,

Alex

[Marte Myrvold]

Hi Alex,

Can you try adding CONFIG_SECURE_BOOT=y to prj.conf?

Best regard,

Marte

[Ryisen]

Hi,

I did and the build went through. Thanks.

Do you know why it wouldn't build without CONFIG_SECURE_BOOT?

Now everytime I connect my board in Segger Embedded Studio I get the (expected) warning "This device is secured. Unsecuring will trigger a mass erase of the internal flash, SRAM and UICR of both the application and network core."

I also get this, when flashing with e.g. nrfjprog.

If I now build a new version of my firmware, how do I get the app_update.bin onto my board without erasing the whole flash?

Best regards,

Alex

Hi Alex,

Ryisen said:

Because CONFIG_BUILD_S1_VARIANT is used by the secure bootloader, so you must enable the secure bootloader for it to work.

Ryisen said:

You must use the bootloader to upload the firmware without erasing, for example putting the device in bootloader mode and using the Programmer app with "Enable MCUboot" selected, using MCUmgr, or using OTA if you have support for that on your device.

Best regards,

Marte

Thanks for your insight.

Which programmer app uses the "Enable MCUBoot" option?

Is it possible to put the device into bootloader mode and send the updated firmware via serial connection? For example, I have an LPC Microcontroller on my board and would like to send firmware to it, and it then sends the new firmware via serial connection to my nRF5340 on the same board.

Best regards,

Alex

Hi Alex,

Ryisen said:

The Programmer app in nRF Connect for Desktop:

See nRF Connect for Desktop for download and nRF Connect Programmer for information on how to use it.

Ryisen said:

Yes, this should be possible. You can use another chip as SMP client as long as the chip supports SMP or can implement it. See mcumgr and SMP for some more information about SMP. A colleague of mine has made a sample where another nRF chip is acting as SMP client, see Bluetooth: Central SMP Client DFU. If the chip is supported in nRF Connect SDK or Zephyr you can use this sample as a starting point. If it is not supported, you will have to implement the SMP client yourself. For this you can try and have a look at SMP Protocol Specification.

Best regards,

Marte
