USB-KW41Z Thread KDS and debug

whistle512 — Fri, 04 Nov 2016 19:16:42 GMT

If I build the router_eligible_device for the USB-KW41Z from the examples folders in C:\NXP\MKW41Z_ConnSw_1.0.2\boards\usbkw41z_kw41z\wireless_examples\thread\router_eligible_device\freertos\kds I get an OK build but no USB emulator debugging.

1)Is Segger's 43_OpenSDA_USB-KW41Z.bin needed for this dongle in order to debug with J-Link?

2)Also, the ProjectCloner for USB-KW41Z projects has a build error: "cannot open linker script file MKW41Z512xxx4_connectivity.ld: No such file or directory"

Thanks for the KDS build capability for Thread!

OK, to answer my own idiocy:

1) yes, you need to get 43_OpenSDA_USB-KW41Z.bin onto the dongle to use J-Link

2) you need to do a clean build of a project BEFORE you clone it. so to clone, say, end_device_ota_client :

a) build end_device_ota_client to create the debug folder and files like MKW41Z512xxx4_connectivity.ld in the original

b) clone that original

Hi David,

I am facing the same issues as you did two months ago.

How did you get your dongle recognized as a J-Link USB emulator?

I tried to flash "43_OpenSDA_USB-KW41Z.bin" on the K22F with my 'real' J-Link box, but with no luck: the dongle was not even recognized by Windows anymore.

Thanks!

Armel

I an having the same issue where the dongle is not recognised as a JLINK debugger/programmer. Did you manage to get this working Armel?

Nope couldn't get it to work.

I was hoping for some help/guidance from NXP.

Hi Armel,

That's disappointing. I'll try and raise it with our local distributor and NXP FAE to see if I can get it resolved.... I'll let you know if I manage to get it sorted.

Cheers

Michael

Hi Armel

I managed to get this resolved....

Take your USB-KW41 (which supports OpenSDA) and connect it to the PC via USB while keeping the 'RESET KW41Z' button pushed. This will start the OpenSDA platform in MSD mode.
After a second relese the push button
The OpenSDA platform will show up as mass storage device (MSD) on the PC just like an USB stick.
Download the OpenSDA image for the USB-KW41Z from https://www.segger.com/downloads/jlink/43_OpenSDA_USB-KW41Z.bin
Load the firmware by simply drag & drop the *.bin file on the device.
After power-cycling the hardware, the OpenSDA platform will show up as J-Link on the PC.

I hope this help

Best regards

Michael

Actually the dongle still doesn't show up as a mass storage device. I will open another thread to ask what should be flashed (with a J-Link) on the dongle's K22F and KW41Z to have it recognized.

Cheers,

Armel
