Cannot use nrf70-wifi-ble-image-transfer-demo in nRF7002 DK

I am using nrf70-wifi-ble-image-transfer-demo in the nRF7002 DK.

I change nothing on the code form the sample, after patching I have succesfully build the code and then flash to the borad.

However, after flashing, there is nothing happending on the nRF7002 DK,even no printing printk("Starting %s with CPU frequency: %d MHz\n", CONFIG_BOARD, SystemCoreClock / MHZ(1));

I checked RTT there is nothing, and the serial terminal will only shows:

I try to debug but when I enter the dubug it can not stop by the main function.

Could you please help me on this, thank you so much!

Hi We just tested on our end with the following .hex file and the DK set up like the images below. Can you try with the .hex file here (just built the project in NCS 2.7.0 as is). devzone.nordicsemi…

Hi

I just added the overlay, I still cannot use the code

I thought I could use "west build -b nrf7002dk_nrf5340_cpuapp" to use the UDP mode, so I didn't include -DEXTRA_CONF_FILE=overlay_tcp_socket.conf

I think it's the problem from nRF7002DK, so I then use an nRF5340 DK the printing is:

After I flash again, the nRF5340 has the same printing problem before. I can not get the printing form nRF7002 DK and nRF5340 DK now.

Could youl please give me some advice？

Hi,

Today I have added the log to be

CONFIG_LOG=y
CONFIG_LOG_DEFAULT_LEVEL=3
CONFIG_USE_SEGGER_RTT=y
CONFIG_LOG_BACKEND_RTT=y
CONFIG_LOG_BACKEND_UART=y
CONFIG_LOG_PRINTK=y

Finally, I can see something from RTT, however, UART is still unavailable, it shows the same problems before.

I notice the SPI from nRF7002 DK's CS(12), CLK(15) and MOSI (13) shows the correct pattern, however, the code reporting

00> [00:00:00.454,437] <err> spi_nrfx_spim: Timeout waiting for transfer complete
00> [00:00:00.660,095] <err> spi_nrfx_spim: Timeout waiting for transfer complete

00> [00:00:03.101,928] <err> spi_nrfx_spim: Timeout waiting for transfer complete

On the other hand, when I using the nRF5340 DK, the arducam can funtion correctly, the logic analyzer shows:

I think nRF7002 DK should have same SPI compared to nRF5340 DK, what is the problems here? Thank you so much!
