Hello again,
I downloaded the USB-KW41Z software and flashed it to the FRDM-KW41Z board. I had to struggle somehow with the FRDM-KW41Z bootloader mode (this document saved me), but finally succeeded in updating the OpenSDA port and loading the border_router scenario on the board.
During this process, several installations of drivers were performed (J-Link, mbedWinSerial, lpc drivers). However, I still cannot see the desired "NXP RNDIS router" in my device manager as expected when following the Kinetis Thread Stack Demo Applications User's Guide, Chap.11, Border router scenarios.
So, I still got the same question : is it supposed to work on FRDM-KW41Z or should I stop now ?
Thank you,
Sterenn
UPDATE : Should stop now and use USB-KW41Z software for USB-KW41Z only.
