@myhexb 串口打印一下启动的日志信息，发上来。

@Twsuts 正常需要初步验证和测试完成以后，底板资料才可以开放。目前核心板已经是稳定版本。

@lej40 The DP interface cannot be configured as a USB3.1 interface. If two USB3.1 interfaces are not enough, it can be extended by using an external USB HUB. Two USB2.0 connectors are reserved on the back of the CP4 machine for users to use.

@顾真牛 有标准PCIE接口，USB3.0不够可以扩展。外置4个USB接口，2个U2 两个U3。一般场景可以满足。

@Twsuts 底板已经在制版中。预计月底可以出来。

Top-level interface

• The 2X20 pin interface is compatible with CP4 and integrates multiple UART, I2C, SPI, CAN and other functions.

• Three function keys are PWR, RST and LOADER.

• 2X2 PIN POE connector，such as CP4.

• 30pin fpc vertical connector can directly drive standard 30PIN EDP interface LCD. Resolution up to 3840 * 2160

• The MICRO HDMI-RX interface can support up to 4KP60 video signal input.

• TF card with self-locking.

• Two native USB3.0 interfaces, one of which supports OTG function.

• Two Gigabit Ethernet interfaces, one of which supports POE function.

• Two HDMI2.1 interfaces with a maximum resolution of 8K.

• Stereo headphone stand with MIC input function.

• Two native USB2.0 interfaces.

• One TYPEC power supply interface, consistent with CP4.

• The external power interface of 2PIN can support DC power input.

• 1 standard PCIE 4X connector, currently only supports PCIE3.0 2X/1X mode.

• SSD interface, only PCIE-M2-2242 size hard disk is supported.

• Standard 7PIN SATA3.0 interface, 4PIN power interface.

• M.2 WIFI module interface, supporting multiple general WIFI modules.

• Dual MIPI LCD interfaces support simultaneous output of two MIPI interface LCDs. The resolution of a single LCD is up to 1920 * 1200. It supports the MIPI DSC function.

• Four independent MIPI camera interfaces support four camera inputs at the same time. It can be configured as 2X4LINE or 4X2LINE mode.

Bot-level interface

• One 30PIN EDP interface can directly drive LCD output.

• MXM 314PIN core board connector.

Welcome to put forward good suggestions. We can consider revising them.

@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

• RTC spare battery specification MS621FE-FL11E_2017-08-18.PDF

• Welding position

@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：
cat /sys/class/drm/card0-HDMI*/edid > /data/edid.bin

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。
