Difficulty using nRF7002EK with nRF54L15PDK on SPI

Hi,

You could try to build the scan sample this way

west build -p -b nrf54l15dk/nrf54l15/cpuapp -- -DSHIELD="nrf7002eb_interposer_p1;nrf7002eb"

For pin mapping, you can look at nrf7002eb pin mapping.

Best regards,
Dejan

An additional note - I believe my issue is related directly to the DT_HAS_NORDIC_NRF7002_SPI_ENABLED flag, which is not getting enabled during build, despite my Devicetree .overlay specifying a nrf7002-spi peripheral.

Perhaps it is an issue with my .overlay file (posted above), but I tried my best to use the working Scan sample as reference, and am able to build successfully, although CONFIG_WIFI_NRF70 ends up not getting enabled.

I appreciate you taking the time to help me solve this!

Hi,

Unfortunately I can't post it publicly here, there is too much identifying information tied up in the filenames and code.

Please let me know if there's some other way I could provide specific information, or if there's a way to send that .zip privately.

Here's my CMakeLists.txt, if it helps:

cmake_minimum_required(VERSION 3.20.0)
find_package(Zephyr REQUIRED HINTS $ENV{ZEPHYR_BASE})
project(myproject)

target_include_directories(app PRIVATE ./src)
target_include_directories(app PRIVATE ./src/dtm)

target_sources_ifndef(CONFIG_DTM_TRANSPORT_HCI app PRIVATE
  src/dtm/transport/dtm_uart_twowire.c
  src/dtm/transport/dtm_uart_wait.c
)

zephyr_include_directories(drivers)
target_include_directories(app PUBLIC ${ZEPHYR_BASE}/subsys/net/ip)

target_sources(app PRIVATE
                   src/main.c
                   src/cli_wifi.c
                   )

Best,

Clyde

Hi,

Can you send your complete project (zipped) including build folder?

Best regards,
Dejan

My build command is:

It seems that despite setting CONFIG_WIFI_NRF70=y in the prj.conf, the build process doesn't accept this config, and in the final build it's not set.

Let me know if you need any other info! Thank you.

Hi,

Which build command did you use?

Can you show your full device tree overlay?

Best regards,
Dejan
