相机采集图像阻塞
-
@lin
功耗是657mW
https://wiki.veye.cc/index.php/RAW-MIPI-AR0234M_Data_Sheet/zh你这个是带负载测量的吗？使能取图之后再测。

@veye_xumm 代码：v4l2-ctl --verbose -d /dev/video0 --set-fmt-video=width=1920,height=1200,pixelformat='NV12' --stream-mmap=4
电源测量结果：

@lin 那就明确了问题所在。你可以先从主板上飞线一个3.3V先测着看看。
-
@veye_xumm 现在不阻塞了，但是采集后保存的图像文件是0字节？？
-
-
@veye_xumm 可以采集了，能否请教一下两者的区别在哪里呢？
-
@lin v4l2-ctl这个命令可能在这个板子的版本有bug。
-
@veye_xumm 您是说，其他相机连上去，v4l2-ctl这个命令采集图像也是会出现问题是吗？是这块板本身的内核缺陷吗？还是其他原因
-
@veye_xumm 请问相机电流能上到360+mA吗，目前有一个可飞线引脚

@veye_xumm 请问FPGA和RK3588直连，没有I2C，怎么在设备树里添加相机？相机驱动又该怎样处理？
