      移植rk628_csi_v4l2驱动到V853上,算是完成了,用命令/sample_driverVipp 0 1920 1080 2 30 0 10 /mnt,能测到MIPI信号了,回复如下

      main:367 make devName[/dev/v4l-subdev35]

      gc2053是原驱动文件的名称,直接在这个文件里改的
      报错代码是写在sunxi_isp.c,static irqreturn_t isp_isr(int irq, void *priv)里的,求大佬给个排查思路

        @xjy_5 在 抓图报错[VIN_ERR]isp0 width error,求给个排查思路 中说:

        首先,isp配置错误

        [VIN_ERR]isp0 configuration error

        isp fifo为空

        [VIN_ERR]isp0 internal fifo full

        isp 帧错误

        [VIN_ERR]isp0 frame lost!

        如果不需要使用isp,可以修改sample的源码删除isp处理部分,并且修改设备树禁用isp

          @awwwwa 感谢回复!这确实是个办法,不过fifo full是溢出的意思吧?

            @awwwwa 真的可以不用ISP就取出CSI的数据??
