hi3531外同步输入(重发)
大家好,最近调试Hi3531外同步,4路1080P输入,SDK包版本为Hi3531_SDK_V1.0.B.2,有中断输入,但所有中断全部丢失。
我是直接使用开发包中的sample_venc 1调试,修改开发包中的SAMPLE_COMM_VI_StartDev->DEV_ATTR_7441_BT1120_1080P,修改如下:
VI_DEV_ATTR_S DEV_ATTR_7441_BT1120_1080P =
{
/*接口模式*/
VI_MODE_BT601,//VI_MODE_BT1120_STANDARD,//addby mayc
/*1、2、4路工作模式*/
VI_WORK_MODE_1Multiplex,
/* r_mask g_mask b_mask*/
{0xFF000000, 0xFF0000},
/*逐行or隔行输入*/
VI_SCAN_PROGRESSIVE,
/*AdChnId*/
{-1, -1, -1, -1},
/*enDataSeq, 仅支持YUV格式*/
VI_INPUT_DATA_UVUV,
/*同步信息,对应reg手册的如下配置, --bt1120时序无效*/
{
/*port_vsync port_vsync_neg port_hsync port_hsync_neg */
VI_VSYNC_PULSE, VI_VSYNC_NEG_HIGH, VI_HSYNC_PULSE,VI_HSYNC_NEG_HIGH,VI_VSYNC_NORM_PULSE,VI_VSYNC_VALID_NEG_HIGH,
/*timing信息,对应reg手册的如下配置*/
/*hsync_hfb hsync_act hsync_hhb*/
{0, 1920, 192,//0,
/*vsync0_vhb vsync0_act vsync0_hhb*/
0, 1080, 41,//0,
/*vsync1_vhb vsync1_act vsync1_hhb*/
0, 0, 0}
}
}
此时cat /proc/umap/vi没有任何中断
参考以前调试3515经验,直接修改《Hi3531 H.264编解码处理器用户指南》视频相关的寄存器:0x20590300,但全部修改无效。
查看《HiMPP 媒体处理软件开发参考》,我修改了VI_DEV_ATTR_EX_S,设置了HI_MPI_VI_SetDevAttrEx,修改如下:
VI_DEV_ATTR_EX_S DEV_ATTR_EX_1080P =
/* 典型时序3:7441 BT1120 1080P@60fps典型时序 (对接时序: 时序)*/
{
/*接口模式VI_INPUT_MODE_E*/
VI_INPUT_MODE_BT601,//VI_MODE_BT1120_STANDARD,//addby mayc
/*1、2、4路工作模式*/
VI_WORK_MODE_1Multiplex,
//VI_COMBINE_MODE_E
VI_COMBINE_SEPARATE,
//VI_COMP_MODE_E
VI_COMP_MODE_DOUBLE,
//VI_CLK_EDGE_E
VI_CLK_EDGE_SINGLE_UP,
/* r_mask g_mask b_mask*/
{0xFF000000, 0xFF0000},
/*逐行or隔行输入*/
VI_SCAN_PROGRESSIVE,
/*AdChnId*/
{-1, -1, -1, -1},
/*enDataSeq, 仅支持YUV格式*/
VI_INPUT_DATA_UVUV,//VI_INPUT_DATA_UVUV,
/*同步信息,对应reg手册的如下配置, --bt1120时序无效*/
{
/*port_vsync port_vsync_neg port_hsync port_hsync_neg */
VI_VSYNC_PULSE, VI_VSYNC_NEG_HIGH, VI_HSYNC_PULSE,VI_HSYNC_NEG_HIGH,VI_VSYNC_NORM_PULSE,VI_VSYNC_VALID_NEG_HIGH,
/*timing信息,对应reg手册的如下配置*/
/*hsync_hfb hsync_act hsync_hhb*/
{0, 1920, 192,//0,
/*vsync0_vhb vsync0_act vsync0_hhb*/
0, 1080, 41,//0,
/*vsync1_vhb vsync1_act vsync1_hhb*/
0, 0, 0}
}
};
此时cat /proc/umap/vi有中断,但中断全部丢失,查看0x20590300,寄存器数据有所变化,但0x20594300(Videv 1)无变化,根据3515的调试经验,外同步输入需要PORT0、PORT1全部有效才行。

上面说的比较多,请问大家也没有调试过Hi3531外同步的,我的思路是否正常,还有没有哪里需要继续配置的。
只有将VI_DEV_ATTR_EX_S->VI_INPUT_MODE_E配置为VI_INPUT_MODE_BT601或VI_INPUT_MODE_DIGITAL_CAMERA才有中断,其他配置全部中断。
谢谢!
我是直接使用开发包中的sample_venc 1调试,修改开发包中的SAMPLE_COMM_VI_StartDev->DEV_ATTR_7441_BT1120_1080P,修改如下:

上面说的比较多,请问大家也没有调试过Hi3531外同步的,我的思路是否正常,还有没有哪里需要继续配置的。
只有将VI_DEV_ATTR_EX_S->VI_INPUT_MODE_E配置为VI_INPUT_MODE_BT601或VI_INPUT_MODE_DIGITAL_CAMERA才有中断,其他配置全部中断。
谢谢!
