@tevet 在全志T113接CVBS摄像头怎么打开VIDEO 节点？中说：

@edisondeng 没有测试过TVD1，测试过TVD0,
可以自己阅读下源码和dts的配置关系，改一下看是否能用。

不行，我改了一下设备树，不太行，内核直接报错了

@yelanwoting 在 rtthread支持T113i支持吗？中说：

比STM32H7性价比高，能支持RTOS吗？

看t113tina的sdk，里面自带了rtossdk，应该支持，我在搞这个，但是卡在编译的地方了

因为有两路tvin，所以想实现同显，但是只有一个video节点，想通过再创建一个tvd节点，但是创建完节点是有两个了，只是内核报错了，报了地址错误，两个节点都用不了了

tvd: tvd@05c00000 {
			compatible = "allwinner,sunxi-tvd";
			reg = <0x0 0x05c00000 0x0 0x00010000>;/*tvd_top*/

			clocks = <&ccu CLK_BUS_TVD_TOP>,
			<&ccu CLK_MBUS_TVIN>;
			clock-names = "clk_bus_tvd_top",
			"clk_mbus_tvd";

			resets = <&ccu RST_BUS_TVD_TOP>;
			reset-names = "rst_bus_tvd_top";

			tvd-number = <2>;
			tvds = <&tvd0>,<&tvd1>;
			status = "okay";
		};

		tvd0: tvd0@05c01000 {
			compatible = "allwinner,sunxi-tvd0";
			reg = <0x0 0x05c01000 0x0 0x00010000>;
			interrupts = <GIC_SPI 108 IRQ_TYPE_LEVEL_HIGH>;

			clocks = <&ccu CLK_TVD>,
			<&ccu CLK_BUS_TVD>;
			clock-names = "clk_tvd0","clk_bus_tvd0";

			resets = <&ccu RST_BUS_TVD>;
			reset-names = "rst_bus_tvd0";

			assigned-clocks = <&ccu CLK_TVD>;
			assigned-clock-parents = <&ccu CLK_PLL_VIDEO1>;

			tvd_used = <1>;
			tvd_if = <0>;
			status = "okay";
		};

		tvd1: tvd1@05c02000 {
    		compatible = "allwinner,sunxi-tvd1";  /* 使用合适的 compatible，可能需要根据芯片手册调整 */
    		reg = <0x0 0x05c02000 0x0 0x00010000>;  /* TVD1 寄存器地址偏移 */
    		interrupts = <GIC_SPI 109 IRQ_TYPE_LEVEL_HIGH>;  /* 建议使用不同的中断号，避免共享 */
    		clocks = <&ccu CLK_TVD>,<&ccu CLK_BUS_TVD>;
    		clock-names = "clk_tvd1", "clk_bus_tvd1";  /* 时钟名称需要与驱动匹配 */

    		resets = <&ccu RST_BUS_TVD>;
    		reset-names = "rst_bus_tvd1";

    		assigned-clocks = <&ccu CLK_TVD>;
    		assigned-clock-parents = <&ccu CLK_PLL_VIDEO0>;
    		
			tvd_used = <1>;  /* 启用 TVD1 */
    		tvd_if = <0>;    /* 接口类型，根据实际连接调整 */
    		status = "okay";
		};

上面的tvd1是我自己加的，tvd0中断号一开始是和tvd一样的107，以为不能用同样中断号，所以改了，发现不是

上面就是报错部分，是不是不能再添加tvd节点了，还是我添加方式有问题？求大佬解答，万分感谢！

Tina5.0 T113的SDKV1.1 版本怎么添加自己的文件

自己在out下面的target下面加个文件就可以

@hahage168 你好，是不是只能创建一个tvd节点

@jasjac 找到了，是因为主控输出的电压和wifi-io的电压不匹配，主控输出3.3v，但是给wifi-io配的电压是1.8，改成3.3，sdio通信就稳定了，不报错，wifi也稳定了

你好，我的也是t113，但是wifi模块是移远f945r，出现sunxi-mmc 4021000.sdmmc: smc 1 p1 err, cmd 53, WR DCE !!的错误，并且我的只有前五秒传输有数据，之后直接掉了，变成0。

@wyljkl 在 T113开机LOGO进入内核闪烁，求补丁中说：

disp-add-uboot-logo-to-kernel-logo-smooth-show.zip

t113的logo闪烁大概率不是这个补丁问题，你要自己找下原因了，补丁你也可以试下

你好，我的是有那种黑色的横条，位置不固定，有时候有有时候没有，我之前改过一段这里面的代码，不改的话会卡死在uboot阶段，我把这一段free_reserved_area(__va(bootlogo_addr), __va(bootlogo_addr + PAGE_ALIGN(bootlogo_sz)), 0x00, "logo buffer");注释了。
这个补丁和我代码好像有点不匹配，是不是还有新的

sqdckll111

@y97788 ! 我的报错和你差不多，注释掉了也没有效果
