RE: Adding a device driver to a nRF Connect SDK Zephyr freestanding application

Thank you very much, that link was what I needed to get my modified driver working!

The only portion of the tutorial that didn't seem to work was

CONFIG_FLASH_NRF_FORCE_ALT=y

can't be set in my case - but it doesn't seem to need to be set.

I really appreciate the help here! I would love if there was an official tutorial post or DevAcademy tutorial that would go through adding a driver to an application and modifying an existing Zephyr driver and the various options that there are (in tree and maintaining a fork, out of tree, for freestanding applications, for workspace applications, etc). Hopefully you can see how I had a hard time finding the post and answer that you linked to. In addition, that post linked to multiple other posts and it gets a bit complicated when it's all through the forum.

Again, thanks for the help Simon!

Check out this reply, which explains how to add an out of tree custom driver to zephyr/drivers/flash (no patching of Zephyr): RE: MCUBoot: adding custom serial flash driver as secondary partition
