2.2 Download firmware into DUT via TLSR8266BR56
The TLSR8266BR56 is used as burning adapter and it is preloaded with the
“8266_evk.bin”.
Method 1: Connect the TLSR8266BR56 with DUT via Single wire (Swire).
1. Connect the miniUSB interface of the TLSR8266BR56 with PC USB via a mini USB
cable.
User can observe the indicating LED to check the TLSR8266BR56: If the light
blinks once, it indicates the TLSR8266BR56 and its connection with PC are both
OK.
2. Connect the pin header of the TLSR8266BR56 with DUT via Swire: connect SWM,
GND and 3V3 of pin header with SWS, GND and 3.3V of DUT, respectively.

Method 2: Connect the TLSR8266BR56 with DUT via USB instead of Swire. This
method only applies to the DUT with USB interface (e.g. dongle board).
1. Connect the miniUSB interface of the TLSR8266BR56 with PC USB via a mini USB
cable.
2. Connect the USB interface of the TLSR8266BR56 with the USB interface of the
DUT.
