Currently, both the official kernel for 6.1 and the mainline kernel for 6.7 are being adapted. Github has already pushed version 6.1, but currently only supports CM5-EVB. Modifications for other machines will be submitted as soon as possible. After the kernel version stabilizes, an updated distribution image will be released.

@george I tried just the HDMI port with two other portable HDMI monitors (7inch LESOWN and 11inch Visual Beat), and they work well. The desktop monitors I tried were a 5inch Samsung and 2 27inch Dell P2715Q's. None of the desktop monitors work. My knowledge of HDMI signaling is limited, but I know the desktop monitors are capable of 4K resolution, but should sync down to the highest resolutions available to them. Is the problem here somehow? Is there a possible work-around (maybe some external hardware to force the desktop monitors to stay at 1K?)

@sushruth
Just upgrade the kernel separately! You can use deb to upgrade or directly command to upgrade.

@george Thank you. Have a good day.

@george 好的，我看看

@jugg 进入MSC模式直接用WINDOWS工具格式化就好了。

@george 跑起来了，是D1贴反了，谢谢啦！不过跑到PCIE3.0出错了，后面要研究下怎么在DTS里边关闭PCIE3.0了。

Refer to the following document to provide EDID information and demesg information for inserting and removing HDMI.

@george got it, thanks! Looking forward for proper wiring solution. Meanwhile, I'll try to put together some custom wiring.

@hangman 不是修改cmdline.txt，应该更新extlinux/extlinux.conf

@edwardzhou
从log信息看USB设备还是有兼容性问题，识别的时候有报错，如果手上有USB hub可以串接hub再测试。或者换一个USB摄像头模组确认一下问题。

@hangman 可能是读卡器兼容性问题，之前有测试过的读卡器如下链接：【淘宝】https://m.tb.cn/h.5kZgqBq?tk=DvWdWeDZbHp CZ3457 「SD卡TF卡USB3.0高速二合一读卡器手机相机内存卡行车记录仪GL3224」

👍 👍 👍 👍

BuildRoot 也要跟上呀

@george 好的

没法自己进入还原系统啊
用的金士顿的U盘

更新2023年发布的loader程序，更换u盘再验证

@jack_admin windows下使用

@airobot机器人开发 好的！正常编译完内核以后需要把modules.tar.gz 解压到文件系统的/lib 目录，这里边主要是一些驱动的ko文件。

@george 好的，谢谢啦！

好的啊👍

@george 十分感谢
