K22F updates using DFU and MCUXpresso

karamanr — Thu, 07 Oct 2021 08:14:48 GMT

Hello,

The main idea of my project is to update the software OTA using MCUBoot, DFU and Mender. I followed this https://hub.mender.io/t/updating-device-firmware-using-dfu-in-zephyr-project-on-a-frdm-k64f-board/1618 to set up MCUBoot and DFU for my board and it all works fine. However, the next step is putting and application build with MCUXpresso on the K22F board. What is the best way to approach this? Do I need to use tools from the Zephyr Project to build my application or is there a tool that I can use with MCUXpresso to build and sign my application?

We have similar question on KVF46f, appreciate for any response.

Hi @karamanr ,

I think to the application, it needn't any special building. You can use MCUXpresso to build it, put the start address in dedicated space and use the tool in Zephyr to sign the image.

Hi and thanks for your reply,
I have tried using the binary built by MCUXpresso and sign it with the Zephyr tools, however it seems that MCUBoot is unable to detect the image when I flash it to the board using DFU.
