USB Driver for nRF52480 in linux with external CPU

[ratnakar1978]

Hi ,

  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

Hello,

You can find an overview of the USB examples here:
http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/examples_usb.html?cp=4_0_0_4_5_50 

A good start may be the USB CDC (virtual COM port) example. Details on the USB library used by the USB examples above is found here:

Best regards,

Hi Kenneth,

     THanks for sharing the information for USB related examples. I already flashed this example on the nRF52480 chipset on the target which is working fine in terms of detection and showing under "lsusb"  as device ID.

 My query is 1) This BLE chipset (nRF52480) is interfaced with external host CPU on the target hardware using USB interface. Now I want to establish communication between host CPU and nRF52480 shipset using USB .

2) I tried to check USB driver in the current linux kernel but I am not seeing USB driver for Nordic chipset which includes Vendor ID, Dev ID and basic IO operations in the driver. Can you please help me for establishing communication between Host CPU and Nordic chipset using USB interface in linux enviornment.

Please let me know if you need more info to understand scenario.

Thanks.
