How to define more than one device (tree) node for QSPI driver

The .zip file has now been removed, and I requested to put the case back to "Public" mode.

Best regards,

Simon

Hi Kazi,

I see what you mean. So basically, I need to update any relevant information for alternative parts in my application, which I can do by reading the alternate device info from the device tree. But the starting point has to be the first node as this is used by the driver at compile time.

If you could remove my project files (.zip) I can make it public again.

Hello Simon,

For nRF5340, CSN is hardware controlled, and you can only add one qspi flash device under one QSPI. it is a hardware restriction of the NRF_QSPI peripheral.

what you can do is to use the SPI peripheral instead, as this has support for software controlled CSN pin(s).

Thanks Kazi,

To build you should use the nrf5340dk_nrf5340_cpuapp board. Include prj.conf & ble.conf & debug.conf and my overlay nrf5340dk_nrf5340_cpuapp.overlay

Hello Simon,

I have made the case private. You can share the project.

Hi Kazi,

Yes I can give you my project, but could you make this ticket private please?

Hello Simon,

Can I look at your application? It shows from the warning that CNFIG_UART_CONSOLE got the value ''n''. You can try to set this ''y'' or both config file of application and the config file of child image.

Hi Kazi,

I still get the same result doing this. I also get initial additional warning

unit address and first address in 'reg' (0x0) don't match for /soc/peripheral@50000000/qspi@2b000/w25q64jq@1

devzone.nordicsemi.com/.../6712.Build-terminal-error-output-_4000_1.txt

I'm thinking that cmake is setup to only taking the first node when setting up the qspi driver?

Regards

Hello Simon,

Have you tried to change the instance number from '0' to '1' on the second node?

Hi Kazi,

Some files for your review

Hello,

It needs to create child node when we define more than one device under one peripheral. Your device tree looks ok.

Can you please share the error log? I also need to look at the zephyr.dts file from the application.

Thanks.
