nRF52840 in target hardware access using lsusb command

[ratnakar1978]

Hi . I have query about  that in the target environment we are using NINA-B301 which us having nRF52840 chipset. Now this chipset is interfaced using USB in the target hardware. Please le me know how can I detect and check the vendor and device ID in the "lsusb" command.

Hi.

The NINA-B301 is a 3rd party module, I do not know what is flashed on that.

You need a firmware which understands USB commands on your device in order to use them.

You can flash one of our USB examples onto the board.

Best regards,

Hi Andrea,

 Thanks for response.

I could flash USBD application and test that on EVK with dedicated Nordic chipset USB port. I am able to read Device ID and Vendor ID on host PC. But please let me know without flashing application like USBD in target hardware , can I detect and access device ID ?

 No, you have to flash a firmware which configures the USB in order to use it.

Hi Andreas,

 Thanks for response. So for flashing I need to use JLINK JTAG and then I can flash any application which does supports USB interface.

Hi.

If you have to use a J-Link Debugger to flash, then use it. I'm not familiar with programming NINA-B301. And yes, you have to flash a application which supports USB interface in order to use it.

Hi Andreas,

  In the target hardware I am able to detect the Nordic chipset nRF52480 by flashing USBD application on the chipset using JLINK SWD.

Now I have query related how I can establish communication from Nordic chipset using USB interface to CPU ?

Which USB generic driver I need to use and where I can update VID,PID for nordic chipset?

Is there any specific driver file is required for Nordic chipset for USB communication with CPU ?

Please share your thoughts .

Thanks,

Ratnakar
