使用的tda4ve+9702 evm环境

运行用例：./vx_app_single_cam.out

选择了，

目前使用的sdk里默认的code，配置如下：

#define RAWTESTPAT_OUT_WIDTH (3840)

#define RAWTESTPAT_OUT_HEIGHT (2160)

#define RAWTESTPAT_I2C_ADDR_8BIT (0x60U)

#define RAWTESTPAT_DES_CFG_SIZE (39U)

/*RAW12*/

#define RAWTESTPAT_OUT_BYTES_PER_LINE ((RAWTESTPAT_OUT_WIDTH * 3 )>>1)

#define RAWTESTPAT_BPLN_HIGH ((RAWTESTPAT_OUT_BYTES_PER_LINE & 0xFF00)>>8)

#define RAWTESTPAT_BPLN_LOW (RAWTESTPAT_OUT_BYTES_PER_LINE & 0x00FF)

#define RAWTESTPAT_OUT_HEIGHT_HIGH ((RAWTESTPAT_OUT_HEIGHT & 0xFF00)>>8)

#define RAWTESTPAT_OUT_HEIGHT_LOW (RAWTESTPAT_OUT_HEIGHT & 0x00FF)

/*Same configuration works for UB960 (Fusion1) and UB9702 (Fusion2)*/

I2cParams ub9702DesCfg_RAWTESTPAT[RAWTESTPAT_DES_CFG_SIZE] = {

{0x32, 0x01, 0x50},

{0x1F, 0x10, 0x1},

{0xC9, 0x32, 0x1},

{0xB0, 0x1C, 0x1},

{0xB1, 0x92, 0x1},

{0xB2, 0x40, 0x1},

{0xB0, 0x01, 0x1},

{0xB1, 0x01, 0x1},

{0xB2, 0x01, 0x1},

{0xB1, 0x02, 0x1},

{0xB2, 0xF3, 0x1},

{0xB1, 0x03, 0x1},

{0xB2, 0x2C, 0x1},

{0xB1, 0x04, 0x1},

{0xB2, RAWTESTPAT_BPLN_HIGH, 0x1},

{0xB1, 0x05, 0x1},

{0xB2, RAWTESTPAT_BPLN_LOW, 0x1},

{0xB1, 0x06, 0x1},

{0xB2, 0x02, 0x1},

{0xB1, 0x07, 0x1},

{0xB2, 0x80, 0x1},/*D0*/

{0xB1, 0x08, 0x1},

{0xB2, RAWTESTPAT_OUT_HEIGHT_HIGH, 0x1},

{0xB1, 0x09, 0x1},

{0xB2, RAWTESTPAT_OUT_HEIGHT_LOW, 0x1},

{0xB1, 0x0A, 0x1},

{0xB2, 0x08, 0x1},

{0xB1, 0x0B, 0x1},

{0xB2, 0x80, 0x1},

{0xB1, 0x0C, 0x1},

{0xB2, 0x04, 0x1},

{0xB1, 0x0D, 0x1},

{0xB2, 0x7D, 0x1},

{0xB1, 0x0E, 0x1},

{0xB2, 0x07, 0x1},

{0xB1, 0x0F, 0x1},

{0xB2, 0x08, 0x1},

{0x33, 0x02, 0x1},

{0xFFFF, 0x00, 0x0} /*End of script */

};

结果保存出的图像数据都是0，raw全黑，yuv全绿

有点怀疑是不是9702没有正常工作或者pattern数据输出有问题。

所以请问，哪些寄存器可以判断9702的工作状态，是否有正确的视频流输出？

感谢！

您好，9702是NDA器件，不方便在公共论坛上回复，关于您的问题我这边给您发个邮件。
