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

george

@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。

george

@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

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.

george

@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？

george

@retroman said in Coolpi 4B armbian support:

Vulkan

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

george

@kingpin1cn 系统固件版本？

george

@tonyone0902 This is usually caused by unstable power supply, such as insufficient input power of the adapter, or power failure at the moment of switching.

@HiramXMaxim Please provide the model of the card reader you use, or take a photo and send it to us. Let's buy the same model and test it. thank you.

george

@HiramXMaxim This may be the compatibility problem of the card reader. You can first make the image into the TF card, and then use the migration script of armbian to migrate the image to EMMC.

@retroman The problem of wifi bt has been solved. Please follow github to submit or download the latest firmware test. Thank you.

@retroman The problem of WIFI BT is being solved. An update will be released in the next few days.

@retroman https://www.cool-pi.com/topic/162/how-to-upgrade-the-boot-loader-of-coolpi-4b?_=1673496991046

george

If you need to boot armbian normally, you need to update the loader file to version 0104.

Follow the steps below to update the loader:

Download the latest loader file One Drive
![5594e1d4-3a7b-46fc-a7b5-2a9fe418dfc0-image.png]
Short the 2 pins shown by the arrow.
The USB interface and computer connection.
Plug in the power supply and open the upgrade software. The machine enters the maskrom upgrade mode.
choose to write by address
Click Execute to complete the loader update.
If the computer prompts that the USB driver cannot be found, please download and install the driver software first.One Drive

george

@retroman Try formatting the TF card before mirroring it. If it does not work properly, it is recommended to upgrade the loader file.

george

@HiramXMaxim The EMMC small board has an adapter for converting to TF card, which can be written to the EMMC using a common card reader. As shown in the figure below.
