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

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>;

        };
};

Re: 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

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

上次那个FT5X06 https://whycan.cn/t_1862.html

不改驱动, 用下面这种配置在申请中断的时候, 会出问题吗?

interrupt-parent = <&pio>;
interrupts = <1 3 IRQ_TYPE_EDGE_FALLING>;
irq-gpios =   <&pio 1 3 GPIO_ACTIVE_LOW>;

Re: 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

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

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

Re: 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

很可能是 CONFIG_MTD_CMDLINE_PARTS=y 这项没勾上, 因为log没有发现分析出mtd分区.

那是不是驱动开发的时候测试没有覆盖到?

大神你是怎么改的,可以分享一下吗?
