Missing boot.ext4 in release

[per1cycle]

由于我目前lp4a上sd卡启动似乎有点问题，只使用emmc烧写来进行对系统的更换，在手头想刷个openwrt。
首先参考了https://github.com/ruyisdk/openwrt-th1520/tree/th1520 ，然后编译中出现了kernel编译，缺少dts等一系列问题，在使用了很trick的方法（复制revy老师firmware中的固件和删除kernel中未使用函数，变量这类）以后最后编译出来的固件烧录之后依然无法启动，具体日志等我晚些重新编译一边提交上来。
于是乎我打算偷懒直接找现成的固件，于是kamisama就指引我到这里来了，但是似乎在release中没看到boot.ext4的文件？ 我看lp4a的烧写脚本似乎需要准备一个u-boot, rootfs.ext4, bootfs.ext4 🥺🥺
以下为原始的烧录bat脚本

:: Script to flash imagess via fastboot, edit image path first

pause
exit

echo IIIIIIIIIIIIIIII Run Cmd:  %CmdStr%

GOTO:EOF

为什么你的 SD 卡启动会有些问题呢？可以详细讲讲吗？
SD 卡启动和我所支持的系统都需要用到这个 u-boot：
https://github.com/chainsx/thead-u-boot/releases

我比较倾向于构建 RAW 镜像然后使用 ums 功能刷写到 EMMC 来简化刷写流程（但是这样做到底简化没有呢？）
刷写方式参考这里：
