Changing Flash parameters in overlay file

[CktDesigner]

My project is using nRF52840.   Early software development used an nRF52840-DK to develop most of the software.   Software is based on Zephyr using nRF Connect version 1.6.1.     I'm using the "littlefs" file system.   I got most things working using the nRF52840-DK.     I now have my custom board and it uses a slightly different (and larger) qspi-nor flash device.   

I'm still using the nRF52840-DK board file, but "modify" some of the parameters using an overlay file.    I know I need to change some of the parameters w.r.t. the flash.    I was able to modify the jedec-id for the new device, but am looking for some documentation that defines the parameters (keywords) in the board definition file (what some of them mean and format of values)   

Can you point me to these definitions (so I don't have to read through a lot of code :-))?

Thanks!

Hi

I have asked our development team to take a look at this, but I'm still waiting for a reply there. Hopefully I'll hear back either today or just over the weekend. Thank you for your patience.

Best regards,

Hi Simon,

I moved on to other issues (and other projects), but am now back to trying to solve this issue.

I'm now using NCS 2.0.0 but having the same issues.     I'm actually using two LFS volumes.  One uses an on-chip storage partition (and works well), and the other attempts to mount the qspi-nor device (for larger data files) and is still having issues mounting...

Any thoughts?

Thanks!
