How to use a NOR Flash GD25Q32E to replace MX25R6435F which is using on the development kit?

Hello Team,

We wanted to use a NOR Flash GD25Q32E to replace MX25R6435F which is using on the development kit. But we got an error. Please see below screen captures.

We also tried like ncs2.6.1\zephyr\samples\drivers\spi_flash. It's able to read this new Flash.

And I attached .overlay file in which the Flash gd25q32 is defined like above samples. So this gd25q32 is able to be used for the data storage. But why it can't be used for the firmware backup? The gd25q32 should be able to be used for both data storage and firmware backup. 

1212.nrf9160dk_nrf9160_ns.overlay

Thank you very much!

Hi,

 

To populate a new device, you can do like this first:

https://github.com/nrfconnect/sdk-zephyr/blob/v3.5.99-ncs1-2/samples/subsys/fs/littlefs/boards/nrf52840dk_nrf52840_spi.overlay#L7

then you add your own flash device, with its jedec-id and timing parameters for entering/exiting DPD.

 

When changing the overlay, I always suggest that you delete your build folder and regenerate the build.

 

Kind regards,

Håkon

Hi,

Thank you for your reply. I have deleted build folder and compile again.

the ovlerlay file have added a new node, this is below:17646.nrf9160dk_nrf9160_ns.overlay

My question is:Is it necessary to partition the flash space from 64Mb to 32Mb in the bootloader.? Because the error message below indicates that Area cannot be found.

Thank you very much!

When using mcuboot, you need to configure it to handle the SPI flash.

That is done by setting up a myproject/child_image/mcuboot.conf file containing something similar to this setup:

https://github.com/nrfconnect/sdk-nrf/blob/v2.6.2/samples/cellular/nrf_cloud_multi_service/sysbuild/mcuboot/boards/nrf9160dk_nrf9160.conf

 

Kind regards,
