Using the nRF secure immutable bootloader to update the application core

[Ryisen]

Hi everyone,

I'm using an nRF 5340-DK and want to update the application core firmware by using the nRF secure immutable bootloader. The bootloader and the network core do not need to be updated.

I used the example project "central_bas" where I added the bootloader by adding "CONFIG_SECURE_BOOT=y" to the prj.conf file. The bootloader works as it gives the expected output to a e.g. Putty console.

Now what I don't unterstand is how to send application firmware images to the bootloader in order to update the application core. I couldn't find any examples in the official nRF Connect SDK documentation. For this I am using nRF Connect SDK v1.9.0.

For testing I tried to program the application core with nrfjprog, but it would give me an error saying that "readback protection" is enabled and I have to flash the complete application core.

What I try to achieve is to send new firmware images to the bootloader, which updates the current firmware on the application core.

Best regards,

Alex

Hi Amanda,

I deleted the entire build folder and reloaded the "central-bas" project, now I get:

When building without "CONFIG_BUILD_S1_VARIANT", everything worked fine.

Hi, 

Can you provide the prj.conf?

I cannot reproduce the issue to build the NCS v1.9.0 "central-bas" project with VScode or west using the following command. 

west build -b nrf5340dk_nrf5340_cpuapp  -- -DCONFIG_SECURE_BOOT=y -DCONFIG_BOOTLOADER_MCUBOOT=y -DCONFIG_BUILD_S1_VARIANT=y

Maybe you can run the "update SDK" in the Tool Manager and then reload the project.

Hi,

my prj.conf file contains the following lines:

# Changed for bootloader
CONFIG_BOOTLOADER_MCUBOOT=y
CONFIG_BOOT_SIGNATURE_KEY_FILE="privMCUBoot.pem"
CONFIG_MCUBOOT_IMAGE_VERSION="2"
CONFIG_BUILD_S1_VARIANT=y

I added "CONFIG_SECURE_BOOT=y" and with this, the build went through.

Do you have an idea why it wouldn't work withouth 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

See my colleague's answer in your post. 

Please don't create duplicated case for the same questions.
