我现在适应983+984，读取983寄存器0x08 = 0x58，寄存器0x0C = 0x01,可以看出已经检测到线路LINK上，使用98x Script Gen v5p3生成的配置如附件，
uint8_t serAddr = 0x18;
uint8_t desAddr0 = 0x58;
uint8_t desAlias0 = 0x5A;
uint8_t McuAddr0 = 0x60;
uint8_t McuAlias0 = 0x60;
WriteI2C(serAddr,0x70,desAddr0);
WriteI2C(serAddr,0x78,desAlias0);
WriteI2C(serAddr,0x71,McuAddr0);
WriteI2C(serAddr,0x79,McuAlias0);
WriteI2C(serAddr,0x88,0x0);
WriteI2C(serAddr,0x89,0x0);
if((FPD0_Rate != FPD4_Strap_Rate_P0)|| (SSCG_FDEV_STRAP != SSCG_FDEV_0)|| (SSCG_FMOD_STRAP != SSCG_FMOD_0)|| (SSCG_TYPE_STRAP != SSCG_TYPE_0))
{
WriteI2C(serAddr,0x1,0x1); //soft reset Ser
delay_ms(100);
printf("Enable I2C Passthrough\n");
uint8_t I2C_PASS_THROUGH = ReadI2C(serAddr,0x7,1);
uint8_t I2C_PASS_THROUGH_MASK = 0x08;
uint8_t I2C_PASS_THROUGH_REG = I2C_PASS_THROUGH | I2C_PASS_THROUGH_MASK;
WriteI2C(serAddr,0x07,I2C_PASS_THROUGH_REG); //Enable I2C Passthrough
delay_ms(1000);
WriteI2C(desAlias0,0x1,0x1); //Soft reset Des
delay_ms(100);
}
else {
printf("Enable I2C Passthrough\n");
uint8_t I2C_PASS_THROUGH = ReadI2C(serAddr,0x7,1);
uint8_t I2C_PASS_THROUGH_MASK = 0x08;
uint8_t I2C_PASS_THROUGH_REG = I2C_PASS_THROUGH | I2C_PASS_THROUGH_MASK;
WriteI2C(serAddr,0x07,I2C_PASS_THROUGH_REG); //Enable I2C Passthrough
}
WriteI2C(serAddr,0x2d,0x1); //Select write to port0 reg
使能了透传，也是设置了透传ID，但是远程读写不了 984的寄存器
984配置的10.8G FPD-LINK IV 单Port
屏参如下
//## Total Horizontal Pixels = 3084
//## Total Vertical Lines = 1662
//## Active Horizontal Pixels = 2880
//## Active Vertical Lines = 1620
//## Horizontal Back Porch = 60
//## Vertical Back Porch = 8
//## Horizontal Sync = 60
//## Vertical Sync = 2
//## Horizontal Front Porch = 84
//## Vertical Front Porch = 32
//## Horizontal Sync Polarity = Positive
//## Vertical Sync Polarity = Positive
//## Bits per pixel = 24
//## Pixel Clock = 307.53MHz
//## PATGEN Enabled
这是什么原因造成的
