楼主辛苦,问下楼主,我的盒子TTL连接,PUTTY跑码全为乱码,为什么?别外,测量GND-RX,GND-TX间电压为0伏,0.05伏,这正常吗?

移动定制:咪咕盒子MG100-U7-HN,内存1G,硬盘4G,CPU 4核,海思3798M ,系统安卓4.4.2目前无法破解。
TTL连接后,超级终端(PUTTY,SecureCRT等)跑码是乱码,测量GND-RX,GND-TX电压为0伏,0.05伏,正常应该为3.3伏左右。因此无法打开ADB。
盒子目前无可用的卡刷包,无法通短接CPU1,2角卡刷。端口扫描器扫描的端口为:33896.但无法连接。
hitool工具无法与盒子正常连接。

短接电容后,GND-TXD电压下了0.03伏,短接电阻后,GND-TXD电压升了4点5。变成4.96伏。

电路板背面有两个三极管的地方,可以正常输出开机信息,在里边的三极管上方,有两个10K欧的电阻,一个电容,两个电阻的里边的角有3.32伏电压,用TTL线的RX端接,超级终端跑码正常,但一直找不到,TTL线的TX端的接点。跑码在下面,Bootrom start
