@大法师 The latest ubuntu22.04 image can already support this camera.

• 20230210-ubuntu-22.04-preinstalled-desktop-arm64-coolpi.rar

• V4L2-TEST can start the camera by operating the video11 node

@jack_admin 那款是定制的MINIPC，CM5的底板是完全重新设计的，接口非常齐全，基本接口下周可以发出来。

@ccjjww1222 可以通过脚本把你做好的系统备份一下。

@xws 部分适配器功率切换瞬间会掉电，会导致机器重启。

@tonyone0902 确认loaer有没有更新到最新，可以按照下图链接更新：https://www.cool-pi.com/topic/162/how-to-upgrade-the-boot-loader-of-coolpi-4b?_=1675398036886

@tonyone0902 卡格式化一下重新制作。

@ccjjww1222 shell输出命令，然后把edid.bin上传：

内核已经更新，同步develop代码到最新，编译替换内核，KO文件解压到/lib/modules目录，重启机器会看到两个WIFI节点。

使用其中一个连接外网

另外一个可以作为热点

@tonyone0902 STA+AP共存驱动部分需要更新。我们尽快处理，请留意内核更新。

@tonyone0902 使用支持TYPEC PD或者QC协议的电源适配器，会默认诱导输出12V电压，如果适配器没有12V的档位，会降低到9V。使用普通的5V适配器实际输出就是5V。

@retroman Has been updated, please check.

@顾真牛 谢谢你的建议。后续考虑支持。

There are many options for LCD with Cool Pi driving edp interface.

• DP directly drives edp
  The two protocols are basically the same. At present, only a few edp interface screens can not be lit normally according to the test results.

DP PIN number	Signal	edp Signal
16	DP_AUXP	eDP_AUXP
18	DP_AUXN	eDP_AUXN
3	DP_TX0P	eDP_TX0P
5	DP_TX0N	eDP_TX0N
9	DP_TX1P	eDP_TX1P
11	DP_TX1N	eDP_TX1N

• Mipi dsi to edp
  Specification LT8911EXB_Datasheet_R1.0.pdf
  

• HDMI interface direct drive
  The RK3588S HDMI interface can be compatible with HDMI or edp functions. By modifying the DTS configuration, the HDMI interface signal can be directly used as an edp signal. The following figure lists the corresponding relationship between HDMI and edp signals.

HDMI PIN number	Signal	edp Signal
2	HDMI0_SBDP	eDP_AUXP
1	HDMI0_SBDN	eDP_AUXN
9	HDMI0_TX0P_PORT	eDP_TX0P
11	HDMI0_TX0N_PORT	eDP_TX0N
6	HDMI0_TX1P_PORT	eDP_TX1P
8	HDMI0_TX1N_PORT	eDP_TX1N
3	HDMI0_TX2P_PORT	eDP_TX2P
5	HDMI0_TX2N_PORT	eDP_TX2N
12	HDMI0_TX3P_PORT	eDP_TX3P
14	HDMI0_TX3N_PORT	eDP_TX3N

Cool Pi does not have a TTL interface. If you want to drive a TTL interface screen, you need to use a bridge chip. At present, the MIPI to TTL interface chip supports ICN6211 by default. The following details how to use ICN6211 to drive a TTL interface LCD module.

• The TTL signal can be output normally by recompiling and replacing the kernel.
  

@retroman The latest firmware is temporarily not compatible with the V10 version of WIFI and BT configurations. This problem will be solved as soon as possible. Please pay attention to the update.

@tonyone0902 上传图片上来看看，HDMI正常是按照EDID来选择分辨率，手动选择之后是可以保存的。不太清楚画面变胖是什么意思？

@retroman said in Coolpi 4B armbian support:

Vulkan

Sorry, Vulkan is not supported for the time being. Please pay attention to the following updates.
