You need to escape the quotation marks with '\' if you want to set the symbol from your CMake file as done in the sample here: https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/blob/ff9429012a8731df7966e5cf777bb4b2310559f7/bootloader_samples/keys_and_signatures/mcuboot_smp_custom_key/CMakeLists.txt#L5

Hi, no worries. Here is a sample that selects a custom signing key: https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/bootloader_samples/keys_and_signatures

Hi Vidar,

Good day!

I apologize for the misunderstanding. What I meant by "secure bootloader" is changing the MCU Boot key for production. Could you please let me know what changes I need to make?

I tried configuring and adding the key, but I ended up with an error.

Thank you!

Hi,

The error message is safe to ignore. It is raised when the app tries to access the emulated flash partition in RAM (partition used to transfer netcore image to the netcore bootloader). With regards to secure boot, this is enabled by enabling CONFIG_SECURE_BOOT.

Best regards,

Vidar

Hi Vidar

I have tested the simultaneous updates it went success now it working.
The reason for previous error is app.conf file is not created.
while the updating the firmware I have received this logs E: Failed to open flash area ID 1: -2

is this a problem?

kindly let me know process for secure boot loader.

Now it back to this error

RE: nrf5340 BLE FOTA With QSPI flash

The linker error indicates that the bootloader (MCUBOOT) is too big to fit into the default flash partition allocated to the bootloader. You can increase the partition size by adding CONFIG_PM_PARTITION_SIZE_MCUBOOT=<new partition size in bytes> (e.g., 0x12000) to your mcuboot kconfig fragment.

I have changed configuration according to the mcuboot_smp_ble_simultaneous code

I am getting FLASH size problem

Do I need to change something

I recommend you test without the static partition file first. You can add it back later when you are ready to lock down the memory layout. This allows the build system to add any missing partitions. You may also try this sample made by one of my coworkers here: https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/bootloader_samples/nrf5340/mcuboot_smp_ble_simultaneous

Hi Vidar,

Thanks for the replay!!!

I added the to the code to mcuboot.overlay.

Additionally i have created empty pm_static.yml file inside the child_image

now this is the error that i am getting.

Hello,

The mcuboot.overlay must also select the QSPI flash device to enable the bootloader to access the external flash:

/ {
    chosen {
        nordic,pm-ext-flash = &mx25r64;
    };
};

Please try to see if it works after making this change.

Best regards,

Vidar
