driver and application files porting from SDK to linux kernel

[ratnakar1978]

Hi Group, currently working on nRF52840 chipset based EVK and able to flash program. But I need to port the chipset driver and required files from nRF5_SDK_15.2.0 SDK to my current linux kernel build which are having all the other device driver integrated. Please let me know which are all files I need to port for basic communication from external CPU to nRF52480 chipset .

Thanks in advance.

Haven't we had this before:

https://devzone.nordicsemi.com/f/nordic-q-a/41595/port-driver-application-in-linux-enviorment-after-testing-done-using-nrf52-sdk

it remains unclear whether you're talking about developing code to run on your Linux system, or just using a Linux system as a development platform to create code to run on the nRF52840 ?

Hi Awneil, We are using Linux Kernel 4.9 under yocto build which is running on main CPU(i.MX7)  board. With this CPU nRF52840 is interfaced with USB2.0 interface. Now with nRF52840 evaluation kit I am able to detect and program the device with "nrfjprog" command line tool as well as with Segger Embedded Studio. My main query is how can I detect the only nRF52840 chipset in target board with CPU using USB2.0 interface under linux OS. and then which basic test applications I can use to run on this chipset.

OK - thanks for clarifying that.

That is the situation I was addressing in my first post - both here and in your other thread.

Nordic have examples where the nRF52840 implements a standard USB CDC/ACM Class device - ie, a "Virtual COM Port".

That would appear on a Linux host as a /dev/ttyusb... - just like a standard USB-to-Serial adaptor.

So, as previously mentioned, look at  Serialisation and the ble-driver-pc

Or just devise your own protocol via the virtual COM Port

Hi Awneil, Thanks for information !!

CAn you please share example name(folder) where I can see the standard USB CDC/ACM Class device.

I will look into serialisation and ble_driver_pc code.

Thanks again.

Go to the documentation library

https://www.nordicsemi.com/DocLib

Choose 'SDK Documentation', and click on 'HTML'

https://www.nordicsemi.com/DocLib/Content/SDK_Doc/nRF5_SDK/v15-2-0/index

In the left-hand panel, choose 'Examples', then 'Hardware Peripheral Examples'

https://www.nordicsemi.com/DocLib/Content/SDK_Doc/nRF5_SDK/v15-2-0/examples_hw_peripheral_devices

Choose 'USB Examples' ...

Thanks !! I could detect the port in linux enviornment.

Excellent.

Time to Verify the Answer, then?
