1.3 Firmware burning instructions

The firmware burning tool and firmware can be downloaded from the official website of Anxin ：https://docs.ai-thinker.com/rtl87xx

1.3.1 Set the module or development board to enter the burning mode

• Module burning process

(1) First of all, will LOG_TX use 2k The resistance is pulled down to the ground （ If the resistance is not used, the serial port of the pull-down part will be stuck, resulting in failure to connect ;
branch , Some serial ports have no effect , After the serial port is stuck, it needs to be loosened LOG_TX Then plug and unplug the serial port again ）;
(2) keep LOG_TX The drop-down , Power up the module or press the reset key （ Silk screen printing is EN, Low level trigger ）;
(3) take LOG_TX Access TTL Modular Rx mouth ;
(4) Open the serial port debugging software , Serial port parameter setting ： Baud rate 115200,8,N,1,16 Base display , If the serial port keeps printing “15”, Then enter the burning mode successfully , The effect is as follows ：

• Development board burning process
  (1) The new version of the development board Type-C USB The serial port connected is Log UART, It can be directly used to burn new firmware ;
  (2) Serial port download software use sdk\tools\AmebaZ\Image_Tool\ImageTool.exe Tools ;
  (3) Connect the Android cable , Press and hold the button on the right and don't release , Press the reset button on the left , after , Loosen the right LOG_TX, At this time, the module enters the burning mode ;
  (4) Check whether the development board enters the burning mode, and the method of using the module above is the same ;

1.3.2 Burn firmware

• When the module enters the download mode, open the burning software sdk\tools\AmebaZ\Image_Tool\ImageTool.exe

• Click... In the tool Chip Select->AmebaD(8721D) Select chip

• Select the file to burn （ With 1484 Take firmware burning for example ）

• Burn the compiled original firmware
  (1) Burn the compiled original firmware ：
  Burning file has 3 individual ：
  KM0boot：（ Burn address ：0x08000000）
  route ：（1484）RTL_AT Download all-in-one firmware _V3.0.1\ Original generated firmware ( Non production firmware )\km0_boot_all.bin
  KM4boot：（ Burn address ：0x08004000）
  route ：（1484）RTL_AT Download all-in-one firmware _V3.0.1\ Original generated firmware ( Non production firmware )\km4_boot_all.bin
  KM4image：（ Address ：0x08006000）
  route ：（1484）RTL_AT Download all-in-one firmware _V3.0.1\ Original generated firmware ( Non production firmware )\km0_km4_image2.bin
  (2) Burn and merge firmware ：（ Address ：0x08000000）
  Firmware path ：（1484）RTL_AT Download all-in-one firmware _V3.0.1\（1484）BAT_BW16_ Customize _16Mbit_v3.0.1_20210712.bin

• Select serial port to set baud rate bit 1500000, Click on OPEN Open the serial port ,Flash Erase Column Size Fill in 2048, Click on Erase Erase the original firmware of the module , And then click download Download new firmware , The effect is as follows ：
  

Be careful

If log Stuck in Uart download server has started…
This is generally because the serial port download mode is not entered , First, confirm whether the serial port has entered the serial port download mode .

2 Firmware burning completion verification operation

When the download is complete , Close firmware burning software , Open the serial debugging assistant , Configure baud rate 115200,8,N,1, Press the development board reset key , You will see the startup information as follows ：

Send instructions “” Query firmware version number , Will reply “”, It means that the firmware is burned and started successfully , The effect is as follows ：
