RE: 请问coolpi 4b 电源输入功率多大合适,有电流保护吗?
@night 机器TYPEC前端电源芯片耐压可以达到28V,极限可以到34V,所以你的适配器规格没有任何问题。
开发板的电源部分一直是我们设计最优先考虑的方向,所以前端第一级电源花了很多功夫,考虑到用户各种各样适配器的规格,最终选择目前国内少数几家真正能做车规级别电源方案的厂家。尽量保证前端电源稳定可靠。

RE: 刷机遇到切换存储emmc失败
@mxpfeng
如果切换还一直失败就可能是EMMC模组有问题了。你可以把镜像做到U盘里边,尝试使用U盘引导机器,然后进入系统以后使用linux命令格式化EMMCsudo mkfs.ext4 /dev/mmcblk0

RE: Freeze after touching around spacebar
@max
I'm very sorry for any inconvenience caused. Thank you for the support of your Coolpi product. I have applied to the company for a new V20 motherboard for you free of charge. Please email your receiving address. george@cool-pi.com -
RE: Freeze after touching around spacebar
@max
I think this is likely caused by a partial malfunction in the power system. You can send an email to george@cool-pi.com I provided a schematic to assist you in analyzing it together, but I did not understand what the first malfunction was like? Can you please provide a detailed description. We deeply apologize for any inconvenience caused to you. -

RE: Cool Pi Cm5-Laptop Linux Quick Start Guide
@guyii
From the phenomenon you described, it appears that the onboard EMMC partition table has been damaged. Try formatting the onboard EMMC memory according to the following operation method. After successful completion, you can enter UMS mode normally.- Find a USB drive and use an etcher to create an image of Ubuntu on it. Remember to back up important data from the USB drive before creating it.
- Insert the USB drive into the USB port of the laptop and start the machine. If everything goes smoothly, the machine will successfully boot from the USB drive.
- Use commands to format onboard EMMC memory
sudo mkfs.ext4 /dev/mmcblk0
- Remove the USB flash drive and press and hold the power button for 10 seconds to forcibly shut down the machine.
- Connect the TypeC port to the X86 computer and press the power button multiple times to enter UMS mode.
