T113-S3 MIPI + LVDS 可以实现吗

[vuiot]

T113-S3 支持 MIPI + LVDS 双屏吗？ 自己做了个板子 MIPI调好了 LVDS 没有一点反应， 有没有相关资料呀 ! 原理图中的效果能实现吗

不 支 持

[vuiot]

@whycan 可以单独用lvds1吗 还是说只能两个lvds lvds1才能用

[hubbell]

能共享一下调MIPI DSI的经验吗？我也是用T113调试，uboot都可以显示logo,到linux kernel就不能显示了，查看了一下，lcd_reset 复位脚位低了，使用lcd_reset =<&pio PD 20 GPIO_ACTIVE_HIGH>, 进入linux后PD20他还是低电平，没有找到为什么？

[vuiot]

@whycan 我看之前论坛有回复 A133 可以这样用 T113-S3不行的 datasheet 上这两个地方看起来差不多

[whycanservice2]

@vuiot 只有一个显示模块，并不能双屏。

[vuiot]

@hubbell 看设备树 我的屏没有 reset

[lansecd]

@hubbell lcd_gpio_0 = <&pio PD 20 GPIO_ACTIVE_HIGH>
试一下

[vuiot]

@whycanservice2 可以单独使用lvds1么

[hubbell]

@hubbell 试过也不行, PD20脚硬件使用4.7k电阻上拉到3.3V，进linux 还是低电平。

此回复已被删除！

@lansecd lcd_gpio_0 = <&pio PD 20 GPIO_ACTIVE_HIGH>; //reset 在Uboot里怎么配置的

[lansecd]

@awwwwa 直接加到设备树（uboot和内核）里面就行了
