@xingzhan2012 可以用cool pi ubuntu系统，直接dd 刷系统到其他存储介质，比如emmc

@AugustRobot_Zou okay!

所有的底层封装操作都是基于访问/sys/class/gpio/

@sushruth Great, thanks for sharing. We'll create the repository later.

@jugg 这个建议不错，需要做这类的参考文档

大法师

上述环境操作不适用于新的镜像版本。

大法师

@jugg
刷一次系统，原系统就被清除了。buildroot也是一种系统构建工具

大法师

@MSUMMERS999
Please confirm the system info, which firmware image be used. You can also download the latest firmware through the onedrive link OneDrive, and the burning method is consistent with the raspberry pi.

大法师

@jugg log没看出异常。建议重新刷镜像固件试下，如果不需要显示，可以下载server版本

大法师

@bg8wj 这个套件目前没在我手上，当时是运行sta模式测试的。你的oled屏显示正常，只是取ip的代码没执行成功吧，给wifi配置连接一个本地网络

大法师

@Mcfly
更新u-boot.img也没有变化？无法运行是什么现象？

大法师

@Mcfly
内核和系统应用不用额外操作。先试下有没有改善，我们目前没有相应的U3相机验证，帮忙排查下，谢谢！

大法师

Sometimes we may need to customize the logo display. We just need to copy logo bmp files to first partition of tf-card or emmc. Two logo files can be the same.

It should be noted that uboot must be upgraded to the latest.

@Mcfly said in Pi4B使用realsense深度相机开机默认识别为USB2.0设备。重新插拔后才能识别为USB3.0设备。:

@george 关闭uboot下USB设备的注册需要改UBOOT代码吗？还是直接上电的时候进uboot改一下就好了？

可以不改代码，串口连续输入CP进入uboot命令行，如果是tf卡启动，输入

CPBOOT# run bootcmd_mmc1

如果是emmc启动，输入

CPBOOT# run bootcmd_mmc0

可以源码修改取消USB扫描启动加载，再编译。也可以先试下我编译好的uboot.img，拷贝到tf卡或emmc的第一个分区system-boot （参考sudo cp uboot.img /boot/firmware/）
uboot.zip

如果是tf卡启动，执行升级命令
CoolPi 4B# c update tf

5242880 bytes read in 423 ms (11.8 MiB/s)
wait for erase...
uboot upgrade ok...
CoolPi 4B#
CPBOOT# c envclr

CPBOOT# reset

如果是emmc启动，执行升级命令
CoolPi 4B# c update mmc

wait for erase...

Insert tf card into Ubuntu OS, delete gpt and create mbr table.

Your answer: q
Using GPT and creating fresh protective MBR.

Command (? for help): q

root@coolpi:/home/coolpi# fdisk /dev/mmcblk1

Welcome to fdisk (util-linux 2.37.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

This disk is currently in use - repartitioning is probably a bad idea.
It's recommended to umount all file systems, and swapoff all swap
partitions on this disk.


Command (m for help): m

Help:

  DOS (MBR)
   a   toggle a bootable flag
   b   edit nested BSD disklabel
   c   toggle the dos compatibility flag

  Generic
   d   delete a partition
   F   list free unpartitioned space
   l   list known partition types
   n   add a new partition
   p   print the partition table
   t   change a partition type
   v   verify the partition table
   i   print information about a partition

  Misc
   m   print this menu
   u   change display/entry units
   x   extra functionality (experts only)

  Script
   I   load disk layout from sfdisk script file
   O   dump disk layout to sfdisk script file

  Save & Exit
   w   write table to disk and exit
   q   quit without saving changes

  Create a new label
   g   create a new empty GPT partition table
   G   create a new empty SGI (IRIX) partition table
   o   create a new empty DOS partition table
   s   create a new empty Sun partition table


Command (m for help): o
Created a new DOS disklabel with disk identifier 0xb1f26e2a.
The device contains 'gpt' signature and it will be removed by a write command. See fdisk(8) man page and --wipe option for more details.

Command (m for help): w

The partition table has been altered.
Calling ioctl() to re-read partition table.
Syncing disks.

@大法师硬盘盒子干脆就找不到usb设备，

硬盘盒需要更新loader，且需要注意适配器供电功率

https://www.cool-pi.com/topic/170/coolpi-4b-loading-from-usb-ssd

大法师

@myhexb 用读卡器连接，插在USB3下层端口，启动试试

大法师

@myhexb 用哪个镜像文件测试？

@ccjjww1222
默认内核驱动未选择CONFIG_INPUT_JOYDEV。

后续默认选配再发布镜像，当然您也可以自行编译更新替换
