nRF5 SDK for Thread and Zigbee OTA Example

[Alexey_B]

Hello DevZone,

I'm using nRF5 SDK for Thread and Zigbee v4.2.0 and trying to test Zigbee OTA example and faced some troubles.

I'm following this guide https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_tz_v4.2.0%2Fzigbee_example_ota_examples.html  and when I need to build the bootloader with command: "make -C bootloader\pca10056\blank\armgcc " there is no such directory in SDK. There only "C:\NRF_SDK_4.2_test\examples\zigbee\ota\bootloader\pca10056\mbr\armgcc" , MBR is Master Boot Record not bootloader.

Is it possible that in SDK 4.2 MBR and bootloader already merged?

Maybe I'm missing something, but where can I find this bootloader?

Hi,

The steps in the documentation are outdated. You should use the bootloader under the mbr folder (examples\zigbee\ota\bootloader\pca10056\mbr\armgcc).

The MBR is used when you are using bootloader, and it is responsible for safe upgrades of the bootloader. 

Best regards,
