2.2 Download firmware
To download firmware into TLSR8278DG48D, first make sure the
TLSR8278DG48D is supplied with power normally. That is, connect the power to the
3V3 of J6, and connect the GND to the GND of J6.
Then connect J6(SWS) of the TLSR8278DG48D 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 TLSR8278DG48D, first make sure the TLSR8278DG48D is
supplied with power normally. That is, connect the power to the 3V3 of J6, and
connect the GND to the GND of J6.
Attach the semi-rigid cable welding steel to the PCBA GND. Then solder wire
core to feed point.
