Wifi and BLE frequency test

Did you try with the sample I linked and was able to detect it? Can I have a look at your application to see if I can recreate it?

Hi,

I ran the code example on my custom board ans on the nrf7002DK but same problem, unknown USB device - A USB device descriptor request failed for both.

Best regards,

Mallory.

Hi.

I would recommend that you start with the sample in zephyr/subsys/usb/console and see what they do just to get the USB running on the app core. After this is working you can add the network core

Hi,

With nrf-gpio-forwarder, it worked, thanks.

But now, I want to communicate with the chip using VCOM instead of UART and RTT viewer.

I think it is possible because D+ and D- are rooted to an USB C port :

I want to have log from APP core on VCOM0 and logs from NET core on VCOM1. Here is the code I use for APP core:

zephyr_udc0: &usbd {
	compatible = "nordic,nrf-usbd";
	status = "okay";

	cdc_acm_uart0: cdc_acm_uart0 {
		compatible = "zephyr,cdc-acm-uart";
		label = "CDC ACM 0";
	};
 
	cdc_acm_uart1: cdc_acm_uart1 {
		compatible = "zephyr,cdc-acm-uart";
		label = "CDC ACM 1";
	};
};

compatible = "nordic,caelimp-nrf5340-cpuapp";

	chosen {
		zephyr,console = &cdc_acm_uart0;
		zephyr,shell-uart = &cdc_acm_uart0;
		zephyr,uart-mcumgr = &uart0;
		zephyr,bt-mon-uart = &uart0;
		zephyr,bt-c2h-uart = &uart0;
		zephyr,sram = &sram0_image;
		zephyr,flash = &flash0;
		zephyr,code-partition = &slot0_partition;
		zephyr,sram-secure-partition = &sram0_s;
		zephyr,sram-non-secure-partition = &sram0_ns;
		nordic,pm-ext-flash = &mx25l32;
		zephyr,wifi = &wlan;
	};

# Enable USB subsystem
CONFIG_USB_CDC_ACM=y
CONFIG_CDC_ACM_IAD=y
CONFIG_USB_DEVICE_STACK=y
CONFIG_UART_INTERRUPT_DRIVEN=y 
CONFIG_USB_DEVICE_MANUFACTURER="4MOD TECHNOLOGY"
CONFIG_USB_DEVICE_PRODUCT="CAELIMP_9192"
CONFIG_USB_DEVICE_SN="0001"
CONFIG_USB_CONFIGURATION_STRING_DESC_ENABLE=y
CONFIG_USB_CONFIGURATION_STRING_DESC="CDC ACM"
CONFIG_USB_DEVICE_VID=0x2804
CONFIG_USB_DEVICE_PID=0x9192
CONFIG_USB_DEVICE_INITIALIZE_AT_BOOT=y
CONFIG_USB_COMPOSITE_DEVICE=y
CONFIG_USB_CDC_ACM_RINGBUF_SIZE=2048
CONFIG_EARLY_CONSOLE=n
CONFIG_UART_USE_RUNTIME_CONFIGURE=n

When I plug the USB on my computer, I don't see the VCOM0 in the connected device area and in the windows manager I have : Unknown USB device - A USB device descriptor request failed.

My questions are :

- Why the board is not reconized ?

- How to enable it for NET core ?

Best regards,

Mallory.

Hi
Do you get any output from the netcore with other samples?

Are you using internal or external clock for the nrf5340? If you are using internal remember that you need to set the clock config in the .config for the network core. You might also need to set CONFIG_BOARD_ENABLE_CPUNET=y on your app core.

Another alternative is that you have forgotten to the following in your overlay

gpio_fwd: nrf-gpio-forwarder {
  compatible = "nordic,nrf-gpio-forwarder";
  status = "okay";

  uart {
    gpios = <&gpio1 1 0>, <&gpio1 0 0>, <&gpio1 5 0>, <&gpio1 4 0>;
  };
};

I tried it on a custom board with nrf5340 and nrf7001 but it is not working (nothing on NET core uart0). All the modifications to switch from nrf7002 to nrf7001 have been made and wifi test is working well.

Hi,

And using VCOM ports like with DKs ?

Hi!
I would not think it is possible without major work on the application which I would not recommend

RE: Wifi and BLE frequency test

MalloryLP — Fri, 26 Sep 2025 15:57:25 GMT

Ok great it worked, many thanks.

Another question : is it possible to merge UART from APP core and UART from NET core in order to have only one UART for both ?

Best regards,

Mallory.

With the 3.1 sample you should not need to set the kconfig anymore. just build with west build -b "board" -p -T

sample.nrf7002.radio_test_combo .

RE: Wifi and BLE frequency test

No problem.

I followaed your recommandations and started a new project based on Wi-Fi: Radio test (Multi domain) with NRF SDK V3.1 and Toolchain V3.1.

I tried to built the project but CONFIG_NRF70_RADIO_TEST_COMBO is not reconnized :💯

Sorry for the delay. My recommendation would be to run this sample on NCS 3.+ as they have made it ready for multidomain out of the box

Hi,

I'm starting with this project : https://docs.nordicsemi.com/bundle/ncs-2.9.1/page/nrf/samples/wifi/radio_test/README.html

Noted, switching to SDK V2.9.1 and toolchain V2.9.1 also.

Best regards,

Mallory.

RE: Wifi and BLE frequency test

runsiv — Mon, 15 Sep 2025 13:15:32 GMT

I would also recommend that you change toolchain version so that it matches the version of NCS you are using.

When you tried this, which sample did you use as starting point? You should be using the wifi/radio test sample

Regards

Runar
