求高人指点！ ISP通路测试 sample_vin_isp_test 报错

xjy_5 LV 5

我在移植RK628D屏幕采集模块到v853上，是CSI 4land接口，开机后电脑已经识别到第二个显示器了

不过信号采集一直有问题，isp一直是config error，我并不清除它究竟是在哪config的
驱动程序里的参数配置如下，IIC是移植RK628驱动原有的regmap操作的，没用到原本的iic操作函数

这个/mnt/extsd/isp0_1920_1080_60_ctx_saved.bin文件是怎么来的，应该往哪个方向排故？

awwwwa LV 6

可以在设备树把isp关闭

xjy_5 LV 5

@awwwwa V853的mipi csi总线到不了750MHZ，这是RK628的最低频率。禁用ISP的话我还有什么方法调用MIPI CSI？在应用层我只知道ISP的应用接口。

xjy_5 LV 5

@awwwwa

手册上说每条land支持1.2Gbps的带宽，也就是说最高频率是600MHZ，但RK628最低是到750MHZ的，用不了，现在看看tc358743怎么样了

DOT小文哥 LV 8

可算看到回头草了，往常都是看到把我们的东西往友商芯片上移的

awwwwa LV 6

@xjy_5 tc358743有现成的驱动，可以试一下

sensor0_isp_used 配置了不使用 ISP

sensor0_isp_used = <0>;

@awwwwa 谢谢大哥！祝大哥福如东海，寿比南山，永远不死，吃嘛嘛香！给大哥递茶

xjy_5 LV 5

@awwwwa 我改了设备树，在sensor文件夹下添加了tc358743，修改了makefile

编译是通过了，不过我怎么调用？

xjy_5 LV 5

@awwwwa 没事了，看到开机就调用了

xjy_5 LV 5

好了，总算能生成的ko文件了，把tc358743文件夹放在/tina-v853-open/kernel/linux-4.9/drivers/media/platform/sunxi-vin/modules/sensor/，修改 Makefile

再修改tc358743文件夹内的makefile

还要配置一下make kernel_menuconfig，搜索dv_timi，选第一个

这就能生成.ko文件了
