Zephyr, MCUboot and FOTA tutorial

[xproto]

I'm trying to achieve FOTA using Zephyr with PlatformIO, but can't find any tutorial yet based on my google searches. I'm using the platform nrf52dk - nrf52832. 

I'm following this blog but I cant go through building the mcuboot part.

With this error. 

error: ARM (defined at arch/Kconfig:28) is assigned in a configuration file, but is not directly
user-configurable (has no prompt). It gets its value indirectly from other symbols. See
http://docs.zephyrproject.org/latest/reference/kconfig/CONFIG_ARM.html and/or look up ARM in the
menuconfig/guiconfig interface. The Application Development Primer, Setting Configuration Values,
and Kconfig - Tips and Best Practices sections of the manual might be helpful too.

Renamed the nrf52_minimal_footprint.conf to mcuboot.conf and dts.overlay to mcuboot_dtc.overlay. The blog doesn't exactly states where those files came from.  I just opened the files in the mcuboot bootloader sample and based on content I think that is the one needed.

Are there any other step by step tutorial with zephyr with mcuboot and FOTA in platformio you know?  or If none at least with zephyr even building via terminal.

TIA.

Hey Xproto!

How to perform a FOTA is well documented on the developer page. I would suggest that you try to follow that instead.

The blog you have there might lack some documentation here and there, and may be not up to date, however the developer page always is. I don't know of any tutorials that use PlatformIO, though that shouldn't stop you from following along with the steps described in the documentation.

Best regards,

Thank you Elfving. Great that the documentation is now based zephyr. I will try this one and get back to you in case there is a problem I can't resolve.
