我在参考datasheet上,使用下面参数:
//AHD 720P 30
{0x33,0x01}, //# CSI0 enable
{0xB0,0x00}, //# Indirect Pattern Gen Registers
{0xB1,0x01}, //# PGEN_CTL
{0xB2,0x01},
{0xB1,0x02}, //# PGEN_CFG
{0xB2,0x33},
{0xB1,0x03}, //# PGEN_CSI_DI
{0xB2,0x24},
{0xB1,0x04}, //# PGEN_LINE_SIZE1
{0xB2,0x0F},
{0xB1,0x05}, //# PGEN_LINE_SIZE0
{0xB2,0x00},
{0xB1,0x06}, //# PGEN_BAR_SIZE1
{0xB2,0x01},
{0xB1,0x07}, //# PGEN_BAR_SIZE0
{0xB2,0xE0},
{0xB1,0x08}, //# PGEN_ACT_LPF1
{0xB2,0x02},
{0xB1,0x09}, //# PGEN_ACT_LPF0
{0xB2,0xD0},
{0xB1,0x0A}, //# PGEN_TOT_LPF1
{0xB2,0x04},
{0xB1,0x0B}, //# PGEN_TOT_LPF0
{0xB2,0x1A},
{0xB1,0x0C}, //# PGEN_LINE_PD1
{0xB2,0x0C},
{0xB1,0x0D}, //# PGEN_LINE_PD0
{0xB2,0x67},
{0xB1,0x0E}, //# PGEN_VBP
{0xB2,0x21},
{0xB1,0x0F}, //# PGEN_VFP
{0xB2,0x0A}
ARM端无法解析出正确的宽和高,无法获取到正确的图像。
请问寄存器配置的是否有遗漏?
谢谢
Kailyn Chen:
您好 ,寄存器0X70 配置为0X1F,为YUV422 10bit mode。在您的寄存器中没看到寄存器0X70的配置。可以试试能否解决您的问题。

我使用如下寄存器配置:
{0x21,0x04}, {0x70,0x1F}, {0x1f,0x03}, {0x33,0x23}, {0x20,0x20}, {0x4C,0x01}, {0x6D,0x7F}, {0x70,0x9E}, {0x7C,0xF8}, {0x58,0x00}, {0x0C,0x81}
示波器得到如下波形,此波形soc端识别不了。
soc端能识别到的波形(同类型其他厂家芯片的波形如下)

图片不出来,就是波形上跟正常的相比,没有明显的4个通道区分,而正常的上能明显看出mipi信号有4个分割线存在。
