TI工程师您好!
现在我们有调试一款HOST->954---953->MIPI 2LANE SENSOR307 LVDS 同轴方式的项目。DS90UB954的IDX、MODE 10K对地 DS90UB953 IDX对地40.2K。目前软件寄存器配置
TI954Q_WRITE_ID:0x60
TI953Q_WRITE_ID:0x30
//Set up Port0
WriteReg(TI954Q_WRITE_ID, 0x4C, 0x01);
//Set up Back Channel Config (0x58)
WriteReg(TI954Q_WRITE_ID,0x58,0x5E);
//Set up SER ID
WriteReg(TI954Q_WRITE_ID,0x5B,0x30);
//Set up SER Alias ID
WriteReg(TI954Q_WRITE_ID,0x5C,0x30);
//Set up Slave/Camera ID
WriteReg(TI954Q_WRITE_ID,0x5D,0x34);
//Set up Slave/Camera Alias ID
WriteReg(TI954Q_WRITE_ID,0x65,0x34);
//Set serializer CSI-2 data input from imager lane to 4 lane, 1.8V VDDIO
WriteReg(TI953Q_WRITE_ID,0x02, 0x33);
//Set GPIO1 and GPIO0 to outputs, where GPIO0 = FSYNC trigger and GPIO1 = IMX390 reset
WriteReg(TI953Q_WRITE_ID,0x0E,0x30);
//Set GPIO1 and GPIO0 to low - confirm snesor is power down mode
WriteReg(TI953Q_WRITE_ID,0x0D,0x00);//0x90
Delay_DelayMs(1);
//Bring GPIO1 high again to prepare sensor for initialization
WriteReg(TI953Q_WRITE_ID,0x0D,0x02);
//enable CSI output and CSI continuous clock, 2lane
WriteReg(TI954Q_WRITE_ID, 0x33, 0x23);
//enable CSI replicate mode
WriteReg(TI954Q_WRITE_ID, 0x21, 0x81);
//enable RX 0 port forwarding to CSI ports
WriteReg(TI954Q_WRITE_ID, 0x20, 0x20);
目前软件一直报953 I2C错误。
有看过很TI论坛贴子。此方面问题很多都是寄存器配置问题。
请帮忙审一下。哪个寄存器是否未配置或者配置错误
谢谢！
