External flash identification error in nrf5340

[erifat]

Hello,

In our project we are using FLASH 2GBIT SPI/QUAD W25N02KVZEIR external flash together with nrf5340. I have made the flash definitions on v2.6.0\zephyr\boards\arm\nrf5340dk_nrf5340\nrf5340_cpuapp_common.dts.

 

We want to use some of the external flash in the project because it is needed for the network core update. But I get an error during the build process. The error output is in the picture.

Thank you for your support.

Hi,

I have made the flash definitions on v2.6.0\zephyr\boards\arm\nrf5340dk_nrf5340\nrf5340_cpuapp_common.dts.

In this image you get a warning stating that you're using Partition Manager, which will cause .dts definitions to be ignored

Could you check if the issues persists if you're not using partition manager or if you set up your partitions using partition manager instead of dts? 

Kind regards;
Andreas

I don't understand how I should do it. We don't want to set up the partition manager right now. It can create the dimensions itself. How should I do it?

I also have some other bad news. The flash you've selected, i.e W25N02KVZEIR  is a SPI-NAND flash. We do not support NAND-devices with our devices. We only have support for SPI/QSPI-NOR flash devices, so the first step will unfortunately be to reevaluate the choice of external flash.

Kind regards,
Andreas

Thank you for your support. We will continue through Nor flash.I'm using the W25Q128JV model winbond flash that we have at the moment. The same problem persists during identification. What can I do at this stage.
