Boot and flash Zephyr OS

Our final purpose is to create a hybrid system on the dragonboard, meaning we are going to dedicate one core to the Zephyr OS to support specific tasks, and the rest of the cores will continue to run some supportable OS. As a first step we are trying to make Zephyr run on the dragonboard, therefore we are need to create an img file to flash over the sd card (after we made the changes needed to support ARMv8 architecture).

I think your board is a bit overkill for running Zephyr. Zephyr is targeted towards small MCUs running from a couple of MHz. There is no boot.img, as this is not x86/Linux. The generated bin is used to flash the board. What are your intentions of running Zephyr on this board? I think you would be better off with some Linux distro. Note that even though Zephyr is supported by a lot of nRF5x based boards, Nordic is not the developers of Zephyr. We cannot provide support on porting to other architectures.

Thanks, i saw some documentation files. I still don't understand how to make the output to "boot.img" file. After compile i got elf and bin (which I understood are relevant and a lot more file), Do I need to convert the elf file to img ?

Can you help with architecture issues ? Zephyr is not support Cortex a-53 (dragonboard architecture) and I don't understand the whole process.

Hi,

You can find all Zephyr related documentation on the Zephyr projects own webpages. I suggest you check out the Zephyr community for help on how to proceed with your contribution.

Best regards,

Jørgen
