@jugg 你买CM5板子以后需要做一条排线才能支持2个或者4个摄像头。默认的排线只能支持1个。

george

@jugg CM5的核心板最多可以出6个CSI接口，CM5的底板目前引出了4个CSI接口，这四个接口在同一个连接器上面。

george

@jugg CM5的机器就可以支持2个CSI的，4B的机器兼容树莓派所以只能1个。

george

@jugg CM5-EVB最多可以支持4个IMX219同时工作。有4个独立的2line通道。

george

@jugg 4B只能支持一个MIPI接口sensor。如果要支持更多sensor可以使用USB接口扩展。

@tmb68 The following figure shows the test results of OpenCl, and the testing method will be provided later.

@jugg 可以支持2个4line或者4个2line的摄像头模组，比如IMX219接口可以支持4个同时工作。

george

@murraytodd Insert your DP cable and print the mesg upload.

george

@Pharizna Please upgrade the loader to the latest version, format EMMC or TF card, and remake the boot image.

george

@Pharizna Can other systems, such as ubuntu, be connected properly

george

@tmb68 said in How to install OpenCL/Kronos/OpenGL on CM5-EVB:

Can anyone provide the steps required to install OpenCL/Kronos/OpenGL on the CM5-EVB?
Looking for support for the Mali-G610, not seeing UserSpace files on ARM or Rockchip sites.
Thanks,
TMB

The released Ubuntu system image is already integrated with G610 driver by default

@Pharizna Please take a photo of the front of your machine.

@wuming 可以尝试按照下面帖子步骤处理：

除了摄像头模组以外，CM5的机器还需要增加一根转接排线，预计下周各个店铺会上线转接排线。

george

@jugg 还可以参考下图方法直接dump出buffer

george

@jugg
可以参考这个：

@Tourists-0 下面这个帖子有介绍GPIO的功能复用，40PIN 可以扩展两路CAN出来。
