Example on how to use samples with nrf52840 Dongle #3

Open tyczj opened 5 years ago

tyczj commented 5 years ago

So far I have only got these examples to work with the nrf52840-DK board and at the time that is all there was I believe. Now there is a more reasonable/smaller nrf52840 option the USB Dongle.

The setup for the DK board does not apply to the dongle because it does not have a debugger on it that you can flash with. I have yet to find a way to get the dongle to work with the LowPAN API fully.

To get where I am today I had to manually build a .hex file with some extra flags

make -f examples/Makefile-nrf52840 clean
make -f examples/Makefile-nrf52840 USB=1 BOOTLOADER=1 BORDER_AGENT=1 BORDER_ROUTER=1 COMMISSIONER=1 UDF_FORWARD=1 LINK_RAW=1
arm-none-eabi-objcopy output/nrf52840/bin/ot-ncp-ftd -O ihex ncp.hex

Whenever register gets called for the LowPANDriver This exception happens in the receiver and transmitter samples with the dongle
