Tina V85x 平台适配双目GC2053的操作步骤
GC2053数据手册： ov-GC2053datas

2.问题背景

Tina V85x 平台支持多目sensor场景。Tina V85x SDK默认配置一般都是单目sensor，比如SDK V1.0默认是单目GC2053。为方便用户适配双目或多目sensor，下面以V853 perf1方案+双目GC2053为例，介绍适配的操作步骤。

3.解决办法

一、双目GC2053适配
适配双目GC2053主要修改以下几处：

1、dts设备树
文件：device/config/chips/v853/configs/perf1/board.dts
修改：

  • （1）修改csi/isp频率
    为节省带宽，可将csi/isp频率由原来默认的300MHz降至200MHz。
vind0:vind@0 {
-			vind0_clk = <300000000>;
+			vind0_clk = <200000000>;
 			status = "okay";
  • （2）修改成离线模式
    因双目场景下，ISP需分时复用，故只能支持离线模式，即work_mode改成1（离线）。 具体可参考->
tdm0:tdm@0 {
-				work_mode = <0>;
+				work_mode = <1>;
 			};
 
 			isp00:isp@0 {
-				work_mode = <0>;
+				work_mode = <1>;
 			};
 
 			scaler00:scaler@0 {
-				work_mode = <0>;
+				work_mode = <1>;
 			};
 
 			scaler10:scaler@4 {
-				work_mode = <0>;
+				work_mode = <1>;
 			};
 
 			scaler20:scaler@8 {
-				work_mode = <0>;
+				work_mode = <1>;
 			};
 
 			scaler30:scaler@12 {
-				work_mode = <0>;
+				work_mode = <1>;
 			};
  • （3）修改sensor配置
    sensor0默认是gc2053，无需修改。但是需要修改sensor1的配置为gc2053。修改后，sensor0和sensor1的配置如下：
sensor0:sensor@0 {
				device_type = "sensor0";
				sensor0_mname = "gc2053_mipi";
				sensor0_twi_cci_id = <1>;
				sensor0_twi_addr = <0x6e>;
				sensor0_mclk_id = <0>;
				sensor0_pos = "rear";
				sensor0_isp_used = <1>;
				sensor0_fmt = <1>;
				sensor0_stby_mode = <0>;
				sensor0_vflip = <0>;
				sensor0_hflip = <0>;
				sensor0_iovdd-supply = <&reg_aldo2>;
				sensor0_iovdd_vol = <1800000>;
				sensor0_avdd-supply = <&reg_bldo2>;
				sensor0_avdd_vol = <2800000>;
				sensor0_dvdd-supply = <&reg_dldo2>;
				sensor0_dvdd_vol = <1200000>;
				sensor0_power_en = <>;
				sensor0_reset = <&pio PA 18 1 0 1 0>;
				sensor0_pwdn = <&pio PA 19 1 0 1 0>;
				sensor0_sm_hs = <>;
				sensor0_sm_vs = <>;
				flash_handle = <&flash0>;
				act_handle = <&actuator0>;
				status	= "okay";
			};

			sensor1:sensor@1 {
				device_type = "sensor1";
				sensor1_mname = "gc2053_mipi_2";
				sensor1_twi_cci_id = <0>;
				sensor1_twi_addr = <0x6e>;
				sensor1_mclk_id = <1>;
				sensor1_pos = "front";
				sensor1_isp_used = <1>;
				sensor1_fmt = <1>;
				sensor1_stby_mode = <0>;
				sensor1_vflip = <0>;
				sensor1_hflip = <0>;
				sensor1_iovdd-supply = <&reg_aldo2>;
				sensor1_iovdd_vol = <1800000>;
				sensor1_avdd-supply = <&reg_bldo2>;
				sensor1_avdd_vol = <2800000>;
				sensor1_dvdd-supply = <&reg_dldo2>;
				sensor1_dvdd_vol = <1200000>;
				sensor1_power_en = <>;
				sensor1_reset = <&pio PA 20 1 0 1 0>;
				sensor1_pwdn = <&pio PA 21 1 0 1 0>;
				sensor1_sm_hs = <>;
				sensor1_sm_vs = <>;
				flash_handle = <>;
				act_handle = <>;
				status	= "okay";
			};
  • （4）修改各video节点的配置
    双目GC2053场景下，可支持的video节点分别为：
    sensor0：video 0/4/8/12
    sensor1：video 1/5/9/13
    故只需修改以上8个video节点的配置即可。修改后的配置如下：
vinc00:vinc@0 {
				vinc0_csi_sel = <0>;
				vinc0_mipi_sel = <0>;
				vinc0_isp_sel = <0>;
				vinc0_isp_tx_ch = <0>;
				vinc0_tdm_rx_sel = <0>;
				vinc0_rear_sensor_sel = <0>;
				vinc0_front_sensor_sel = <0>;
				vinc0_sensor_list = <0>;
				work_mode = <0x1>;
				status = "okay";
			};

			vinc01:vinc@1 {
				vinc1_csi_sel = <1>;
				vinc1_mipi_sel = <1>;
				vinc1_isp_sel = <1>;
				vinc1_isp_tx_ch = <0>;
				vinc1_tdm_rx_sel = <1>;
				vinc1_rear_sensor_sel = <1>;
				vinc1_front_sensor_sel = <1>;
				vinc1_sensor_list = <0>;
				status = "okay";
			};


			vinc10:vinc@4 {
				vinc4_csi_sel = <0>;
				vinc4_mipi_sel = <0>;
				vinc4_isp_sel = <0>;
				vinc4_isp_tx_ch = <0>;
				vinc4_tdm_rx_sel = <0>;
				vinc4_rear_sensor_sel = <0>;
				vinc4_front_sensor_sel = <0>;
				vinc4_sensor_list = <0>;
				work_mode = <0x1>;
				status = "okay";
			};

			vinc11:vinc@5 {
				vinc5_csi_sel = <1>;
				vinc5_mipi_sel = <1>;
				vinc5_isp_sel = <1>;
				vinc5_isp_tx_ch = <0>;
				vinc5_tdm_rx_sel = <1>;
				vinc5_rear_sensor_sel = <1>;
				vinc5_front_sensor_sel = <1>;
				vinc5_sensor_list = <0>;
				status = "okay";
			};


			vinc20:vinc@8 {
				vinc8_csi_sel = <0>;
				vinc8_mipi_sel = <0x0>;
				vinc8_isp_sel = <0>;
				vinc8_isp_tx_ch = <0>;
				vinc8_tdm_rx_sel = <0>;
				vinc8_rear_sensor_sel = <0>;
				vinc8_front_sensor_sel = <0>;
				vinc8_sensor_list = <0>;
				work_mode = <0x1>;
				status = "okay";
			};

			vinc21:vinc@9 {
				vinc9_csi_sel = <0>;
				vinc9_mipi_sel = <0x0>;
				vinc9_isp_sel = <0>;
				vinc9_isp_tx_ch = <0>;
				vinc9_tdm_rx_sel = <0>;
				vinc9_rear_sensor_sel = <0>;
				vinc9_front_sensor_sel = <0>;
				vinc9_sensor_list = <0>;
				work_mode = <0x1>;
				status = "okay";
			};


			vinc30:vinc@12 {
				vinc12_csi_sel = <0>;
				vinc12_mipi_sel = <0x0>;
				vinc12_isp_sel = <0>;
				vinc12_isp_tx_ch = <0>;
				vinc12_tdm_rx_sel = <0>;
				vinc12_rear_sensor_sel = <0>;
				vinc12_front_sensor_sel = <0>;
				vinc12_sensor_list = <0>;
				work_mode = <0x1>;
				status = "okay";
			};

			vinc31:vinc@13 {
				vinc13_csi_sel = <1>;
				vinc13_mipi_sel = <1>;
				vinc13_isp_sel = <1>;
				vinc13_isp_tx_ch = <0>;
				vinc13_tdm_rx_sel = <1>;
				vinc13_rear_sensor_sel = <1>;
				vinc13_front_sensor_sel = <1>;
				vinc13_sensor_list = <0>;
				status = "okay";
			};

2、内核配置
双mipi sensor场景下，ISP分时复用，需要使用TDM，故需打开TDM。
文件：device/config/chips/v853/configs/perf1/linux/config-4.9
修改：打开TDM配置

CONFIG_SUPPORT_ISP_TDM=y
CONFIG_TDM_LBC_EN=y

3、mpp middleware

首先，确保mpp配置中选中了gc2053 sensor。检查方法：
make menuconfig，依次进入配置项：

Allwinner  --->
    eyesee-mpp  --->
        [*]   select sensor
        [*]     use sensor gc2053

然后，在ISP效果文件中，为第二个sensor添加效果文件配置。
位置：external/eyesee-mpp/middleware/sun8iw21/media/LIBRARY/libisp/isp_cfg/isp_ini_parse.c
修改：将原来的两组gc2053_mipi配置分别拷贝一份，然后修改名字为gc2053_mipi_2即可，其他参数不用修改。

struct isp_cfg_array cfg_arr[] = {
...

#ifdef SENSOR_GC2053
	{"gc2053_mipi",  "gc2053_mipi_isp600_20220511_164617_vlc4_day", 1920, 1088, 20, 0, 0, &gc2053_mipi_v853_isp_cfg},
	{"gc2053_mipi",  "gc2053_mipi_isp600_20220415_144837_ir", 1920, 1088, 20, 0, 1, &gc2053_mipi_ir_isp_cfg},
	{"gc2053_mipi_2",  "gc2053_mipi_isp600_20220511_164617_vlc4_day", 1920, 1088, 20, 0, 0, &gc2053_mipi_v853_isp_cfg},
	{"gc2053_mipi_2",  "gc2053_mipi_isp600_20220415_144837_ir", 1920, 1088, 20, 0, 1, &gc2053_mipi_ir_isp_cfg},
#endif

...
}

按以上步骤修改完成后，需重新编译mpp和固件，命令如下：

cleanmpp && mkmpp && mp

二、双目GC2053验证
支持验证双目GC2053的mpp sample有：
sample_rtsp（支持双目采集+编码+RTSP）、sample_smartIPC_demo（支持双目采集+编码+RTSP+人形检测）、sample_smartPreview_demo（支持双目采集+预览）
如果不需要RTSP功能，注释掉代码中的宏 #define SUPPORT_RTSP_TEST 即可。
有关mpp sample的使用方法，请参考 https://bbs.aw-ol.com/topic/1906/
