@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。

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

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

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

@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：
https://askubuntu.com/questions/1326386/ubuntu-20-04-lts-driver-intel-wi-fi-6e-ax210-160mhz

@wuming dmesg| grep hci0

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：
https://gitee.com/andyshrk/drm/blob/master/tests/ovltest/ovltest.c
或者 drm 下面writeback 的使用方法参考：
https://patchwork.kernel.org/project/dri-devel/patch/20220812231757.1454-3-quic_rohiiyer@quicinc.com/

@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。
https://www.cool-pi.com/topic/68/coolpi-4b硬件扩展一-40pin接口介绍?_=1682384241578

george

@wuming 机器的40pin排针旁边有版本号

george

@wuming 你手上是V10的机器吗？V10的暂时不支持蓝牙！可以联系一下代理更换一下V11的底板。

george

@wuming lsusb 发一下结果，然后内核要同步到最新。

george

@Pharizna Try using a USB disk or SDcard to start

george

@wuming 恭喜！！有空的话可以整理一下你的调试步骤，方便后面进来的小伙伴学习。

george

@顾真牛他如果需要环境调试，我们可以提供。

Q: 写一首描绘冬天的诗

A:  漫天雪花飞舞,
寒风呼啸,大地一片沉寂。
冬天的气息弥漫,
银装素裹的世界令人陶醉。

树枝上挂满晶莹剔透的冰霜,
寒风把它们吹得摇曳生姿。
湖面上结满了厚厚的冰,
划着小船的人们欢笑着前行。

冬天是一个美丽而神秘的季节,
让人感受到宁静和祥和。
虽然它带来了一些不便,
比如冷的天气和冰雪的覆盖,
但它也是一年中最美好的时光。<eop>
