I have made FRDM-KW24D512 work with iMX Ultralight linux board. The FRDM-KW24D512 was plugged in the Arduino connector in the iMXUl6 board and they work as Thread border gateway. Eveything works.
Now I want to make the FRDM-KW24D512 to work with raspberry pi. According to the documentation, the connection
between the FRDM-24D512 and any linux host need to be UART. I have connect the UART of both. However
the firmware(thread_host_controller_device_imx6ulevk) ) in FDRM-25D512 is not running properly. Should I connect some more wires between the FRDM-24D512 and the raspberry pi besides UART?
