现在弄GT911的驱动触摸在内核里面已经上报了坐标了在内核打印出来

现在弄GT911的驱动触摸在内核里面已经上报了坐标了在内核里面打印出来了但是写个测试函数去读取event0的坐标时候总是读取read为小于0
下面的是我的一个测试函数

晕哥说：

用 ev_test 或者直接 cat /dev/input/eventX 呢？有没有数据?如果这样也没有，检查看是否进入了驱动的中断

进去一看发现input下面有两个event0 和event1 我以前一直读取的是event0 所以一直读取不到

这是我的配置文件
&i2c0 {
status = "okay";

goodix_gt911_2:goodix_gt911_2@5d{
compatible = "goodix,gt911";
reg = <0x5d>;
interrupt-parent = <&pio>;
interrupts = <1 3 IRQ_TYPE_EDGE_FALLING>;
reset = <&pio 1 2 GPIO_ACTIVE_LOW>;
irq-gpios = <&pio 1 3 GPIO_ACTIVE_LOW>;

};
};

晕哥说：

那现在可以读到了 ? /dev/input/event1 ?

是的

哈哈
这没有啥主要是那个I2C里面按那个配置了还是就是选中那个gt911的触摸芯片就没有问题了

无情一刀 · 2018-12-12 15:57:24

我的配置就是那样改的在里面申请中断没有问题，现在我也是想把上次那个edt-f5x05也改为这样方式，这不昨天重新clone一个Linux 现在下载到板子里面
出现5S重启，不是jffs的问题我用好的板子烧写了内核的dtb 和zImage 没有烧写jffs 。还是一样的会出现下面截图

无情一刀 · 2018-12-12 16:25:24

晕哥说：

dts有没有添加spi flash设备, mtd分区有没有解析出来, 有没有添加 jffs2 驱动?
对照启动 log 都检查一下

uboot我没有动以前还是可以用的就是我重新下载了linux 4.13.16,我内核里面的dts和dtsi都是按照以前去设置的
