build openwrt souce codeposted in Openwrt
step1:
git clone https://gitee.com/yanyitech/openwrt.git cd openwrt ### Quickstart 1. Run `./scripts/feeds update -a` to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default 2. Run `./scripts/feeds install -a` to install symlinks for all obtained packages into package/feeds/ 3. Run `make menuconfig` to select your preferred configuration for the toolchain, target system & firmware packages. 4. Run `make` to build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

RE: 关于离线刷Android boot（无EMMC）， 试了烧录方式都无法启动问题， 有没有大神知道什么回事posted in Pi 4B
-
单独拿一个U盘，使用refuse工具，将udisk install专用目录下的镜像刷入U盘。
-
将做好的U盘插入4B主板USB3端口（下面一个），插上TF卡，上电开机。
-
如果有接HDMI显示器，可以查看安装过程（全自动安装），安装结束提升拔出U盘。
-
按power按键开机，启动进入安卓系统。

RE: cool pi 4b & CM5 linux system support compile u-bootposted in Ubuntu
本机也可以直接编译u-boot源代码。
补充安装依赖，再更新编译脚本
sudo apt install device-tree-compiler python2
