2.2 Download firmware
To download firmware into TLSR8278DK48D, first make sure the
TLSR8278DK48D is supplied with power normally. That is, connect the power to the
3V3 of J18, and connect the GND to the GND of J18.
Then connect J18 (SWS) of the TLSR8278DK48D with SWM of a burning EVK.
Meanwhile, connect the miniUSB interface of the burning EVK with PC USB.

2.3 Test RF signal
To test RF signal of TLSR8278DK48D, first make sure the TLSR8278DK48D is
supplied with power normally. That is, connect the power to the 3V3 of J18, and
connect the GND to the GND of J18.
In conducted mode, connect SMA connector to spectrum analyzer, or other RF
instruments. In radiated mode, connect SMA connector to external antenna.
