刷入固件步骤

    1. 拆开电池后盖观察主板是否是如下图所示。(或者查看主控是否为TLSR8359)

焊接图示

    1. 焊接 GND, VCC, RX, RTS四根线。
    1. 使用usb2ttl模块(CH340)链接焊接的四根线。其中rx 链接 tx, tx链接 rx, vcc链接3.3v, GND链接 GND。RTS飞线和芯片CH340G第三脚链接(也可不焊,烧录前手动和GND连一下)。
    1. 打开https://atc1441.github.io/ATC_TLSR_Paper_UART_Flasher.html 波特率选择默认 460800,Atime默认,文件选择Firmware/ATC_Paper.bin
    1. 先点击unlock,再点击write to flush,等待完成。成功后,屏幕会自动刷新。

项目编译

    cd Firmware
    makeit.exe clean && makeit.exe -j12

成功后提示内容:
