A greate tool for creating disk imageposted in Maker
Genimage - The Image Creation Tool
genimage is a tool to generate multiple filesystem and flash/disk images from a given root filesystem tree. genimage is intended to be run in a fakeroot environment.
It also supports creating flash/disk images out of different file-system images and files.
Configuration is done in a config file parsed by libconfuse. Options like the path to tools can be given via environment variables, the config file or from commandline switches.

Coolpi 4b/cm5 android install with Udiskposted in News
use rufus tool
Download system iso file, then run the tool that make a bootable USB stick.
Example: Image file name coolpi-sdcard.img
Insert the USB stick into the blue USB3.0 port (the bottom one) of 4b board, then power up and wait for automatic installation to complete. User can view installation status via serial port or hdmi out display.

RE: Cool pi 4B & CM5 探索快速安装系统新方法posted in Maker
@edwardzhou said in Cool pi 4B & CM5 探索快速安装系统新方法:
最近一直在用这个方法，非常太好用太方便了。
我对上面的备份安装放在同一个U盘实现的方法，做了一些改进，通过启动菜单选择 备份 还是 安装， 比每次去改 initrd.img 要方便很多。
步骤1. 编辑 /extlinux/extlinux.conf 如下
menu title Select the boot mode TIMEOUT 60 default Linux coolpi backup label Linux coolpi backup kernel /Image initrd /initrd-backup.img fdt /rk3588s-cp4.dtb append root=LABEL=writable rw rootfstype=ext4 console=ttyS0,115200n81 quiet splash plymouth.ignore-serial-consoles vt.global_cursor_default=1 irqchip.gicv3_pseudo_nmi=0 net.ifnames=0 label Linux coolpi install kernel /Image initrd /initrd-install.img fdt /rk3588s-cp4.dtb append root=LABEL=writable rw rootfstype=ext4 console=ttyS0,115200n81 quiet splash plymouth.ignore-serial-consoles vt.global_cursor_default=1 irqchip.gicv3_pseudo_nmi=0 net.ifnames=0步骤2， 把 install 中的 initrd.img 复制过来，并改名为 initrd-install.img
步骤3， 把 backup 中的 initrd.img 复制过来，并改名为 initrd-backup.img
U盘查到板子上，上电启动。
你局可以看到菜单Capacity: 30436.5 MB = 29.7 GB (62333952 x 512) ... is now current device Scanning usb 0:1... Found /extlinux/extlinux.conf Retrieving file: /extlinux/extlinux.conf reading /extlinux/extlinux.conf 629 bytes read in 39 ms (15.6 KiB/s) Select the boot mode 1: Linux coolpi backup 2: Linux coolpi install Enter choice:输入1 或 2 回车即可，默认是1， 60秒无输入，则自动启动backup
可以参考 edwardzhou 整理的内容

RE: Coolpi 4b support dynamic update logoposted in Pi 4B
@大法师 said in Coolpi 4b support dynamic update logo:
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.
