硬件与荔枝派zero 一样？
I2C SCK/SDA 有没有上拉？

daydayup · 2017-11-14 14:22:19

果然是没有上拉，这坑挖大了。
我去飞线试一试。

daydayup · 2017-11-14 14:24:49

飞线就好了，谢谢大神.

请问一下，我不用触摸屏，如果关闭上面的错误提示，我是用buildroot编译的，在make menuconfig里面去掉了tslib,现在改怎么办？谁知道回复一下，谢谢

晕哥 · 2018-07-18 11:11:37

在设备树里面删除 ns2009 即可

打开 arch/arm/boot/dts/sun8i-v3s-licheepi-zero.dts

删除:

&i2c0 {
status = "okay";
ns2009: ns2009@48 {
compatible = "nsiway,ns2009";
reg = <0x48>;
};
};

重新编译出 dtb 文件, 烧录.

谢谢了，

请问一下，我现在遇到同样的问题，上拉也给安排上了，但是还是一样的错误，这是怎么回事？

@jkl
是不是上拉没起作用？
