NRF qspi nrf7002

Quick qestion

Making a new board with external memory(jedec) and using SQSPI as I have to put it into cpuflpr_vpr(does not work with QSPI). Works fine !!

but I also plan to have a nrf7002 chip on board. And why not use the same spi bus. Is this possible? or should I use a normal SPI bus for both instead?

nrf70: nrf7002@0 {

compatible = "nordic,nrf7002-qspi";    -> gives error saying: "Node should only occur on the qspi bus."

Hi Perre,

As of now, its a limiatation that the SPI bus for the nRF7002 can only be used on the nRF7002; there can't be more devices on the same bus.

Ah, but sounds strange.. Do I understand it correctly as
I can not run both Flash and NRF7002 on the same normal SPI, and instead have to use SQSPI for flash and normal SPI on separate pins on the NRF54L15 to the NRF7002?

Or is it ok to use a normal SPI for both? I have separate chip select for each device..

Yeah as long as you do it on seperate pins, or on a seperate SPI instance it is fine. So you can have multiple SPI buses with multiple devices, but the one for the nRF7 needs to stand alone.

Hello Elfving, sorry for refloating this. i'm also building a board with the nrf7000, the nrf54l15 and a nrf91. my doubbt here is. in the thingy91, i've seen that all the nrf91,nrf54l,nrf7000 and flash share the same SPI. in my case i'm only using a regular spi for the flash, not a fancy qspi. will it be fine if all of them share the same spi bus?
