Flashing an application using the Actinius I/O Serial Programmer

[Neso]

Hi. I'm trying to flash the Cell Fund Lesson 4, Exercise 1 app – Reading buttons and controlling LEDs over MQTT, to an Icarus IoT Board v2 using the Actinius I/O Serial Programmer via usb.

I'm using SDK v2.8.0 and have flashed this successfully to the Thingy91.

I tried clean builds, and also tried including the following to prj.conf for the Icarus IoT Board v2 build with board target actinius_icarus/nrf9160/ns

CONFIG_BOOTLOADER_MCUBOOT=y

CONFIG_BUILD_OUTPUT_BIN=y

App builds fine, but I can't find the app_update.bin file. (or zephyr.signed.bin) and trying to flash any other *.bin file from the <path>MQTT_broker\IcarusBuild\MQTT_broker\zephyr folder gives an "Upload failed Firmware is not a valid device image." message.

What am I doing wrong?

Hi,

Do you see the same behavior when using any older NCS version?
You could try the same exercise for NCS v2.4.0-v2.6.2 and for NCS v2.2.0-v2.3.0.

How are Thingy91 and Icarus IoT board related in your case regarding existence of update files?

Best regards,

Haven't tried older versions. What do you mean by update files?
I see that my nrf9160 and icarus builds are missing the mcuboot folder completely. Trying to figure that out at the moment.

Hi,

Have you tried to remove build folder before rebuilding?

Yes,and as I said, I also tried building new applications from scratch. All clean builds.

Hi,

To summarize, when you had CONFIG_BOOTLOADER_MCUBOOT=y in your prj.conf, you were able to build and flash the project to your board but you did not have files neccesary for updating the application. When you removed CONFIG_BOOTLOADER_MCUBOOT=y from your project configuration and added SB_CONFIG_BOOTLOADER_MCUBOOT=y in the sysbuild.conf of your project's root, you are not able to build the project anymore. Is this correct? If this is correct, can you provide a full build log including your build command?

Best regards,

No.. I'm able to build and flash successfully to the Thingy91, but building for the Icarus IoT V2 does not generate an app_update.bin (or zephyr.signed.bin) file, so I'm unable to flash it.

With SB_CONFIG_BOOTLOADER_MCUBOOT=y in prj.conf, nothing changed. Still no bin file.

When I included a sysbuild.conf file with SB_CONFIG_BOOTLOADER_MCUBOOT=y like you said, the build fails.
 
Files included. See Build_Fail.txt for build log. Wasn't able to include it here.

Hi,

Your Build_fail.txt file appears to be empty. Can you check this and re-upload?

I get errors when trying to paste it into this section.

Hi,

I can see in your log that conflicting file names have been discovered by the build system.

CMake Error at C:/ncs/v2.8.0/zephyr/cmake/modules/extensions.cmake:2842 (message):
  Conflicting file names discovered.  Cannot use both
  actinius_icarus_nrf9160.conf and actinius_icarus.conf.  Please choose one
  naming style, actinius_icarus_nrf9160.conf is recommended.

You could try to resolve this naming issue.

Best regards,
Dejan

Holy.. Not sure how I got this conflict, but I deleted and installed board files again. It worked.

My colleague got the same duplicate file error on Mac. Is it something wrong in the nRF connect install?
