IMX307 i2c 读取的值都是0xff
-
Imx 307的摄像头，搭配jetson nano 4g的板子使用，能正常通过stream获取图像，但是通过bsp中的cs_mipi_i2c.sh读取所有的参数，返回的都是类似0xff的值，jetpack 4.2.2，安装的是4.6.2的bsp，供电使用5V供电（nano的引脚输出的5v电压）

@beck
你用的nano型号是什么？有两个mipi接口的吗？ 那么i2c bus number应该是7或者8.
摄像头默认的i2c addr应该是0x3b----如果你没有改过的话。 -
nano 是b01的，连个mipi接口。我没有改过i2c addr，但是上面的截图上看到的0x3b显示的是UU，而且我不指定-d，使用默认的0x3b地址，读取到的值也是0xff

@beck 执行一下
dmesg | grep 307
发上来我看看 -
@veye_xumm 我先换个tx2 nx的板子试试
-
@veye_xumm 我的tx2 nx上面的L4T的版本是，我发现下面这个链接里面下载的最新的release文件，但是里面没有对应的版本的Image，请问这个怎么 处理？https://github.com/veyeimaging/nvidia_jetson_veye_bsp/releases

-
@beck 不好意思，最新版本的我们现在还在开发中。尚未发布。现阶段只能先将tx2 nx退回一个版本了。
-
@veye_xumm 好的，我这使用tx2 nx，退回到了4.6.3就搞定了

@beck 帅啊~
