Hi Hakon,

Can you please share other related files(like C files and all) if it is possible? I also wanted to test the same scenario over the nrf54l15DK to the nrf7002EK board.

I am using nRF Connect SDK v3.1.0

Thanks,
Maulik

Thanks Håkon, that was part of the problem and it is working now.

I also had MISO and MOSI mixed up, even after checking my wiring several times!

For anyone interested, here is the working overlay:

Hi,

[quote user=""]It seems that the build system is linking in files that expect to be using QSPI only and the log indicates that it is running functions that use QSPI.[/quote]

It will run on SPI, as indicated by the first lines:

[00:00:00.004,598] <inf> wifi_nrf_bus: SPIM spi@c7000: freq = 1 MHz
[00:00:00.004,618] <inf> wifi_nrf_bus: SPIM spi@c7000: latency = 0

The remainder is due to common file for both transports.

This pin needs to be changed:

host-irq-gpios = <&gpio2 6 GPIO_ACTIVE_HIGH>;

as P2 does not have a GPIOTE instance.

Could you try this and report back?

Kind regards,

Håkon
