VIM3L上改如何修改分区大小

Technical Support
1

您好，Khadas团队
当前我的硬件条件是VIM3L,软件是Android12，
我现在需要下载的Super.img是1.8G，但是从uboot中看到的super分区大概也只有1.8G左右，我在device下的BoardConfig中配置了super分区的大小，但是似乎实际上还是Uboot里的分区是有效的，
我尝试在uboot阶段使用Part命令去修改（先设置环境变量super_size=0x00380000,然后使用part size mmc 2 8 super_size），但是无效果，请问下可以告知下如何进行修改吗？

Hello, Khadas Team
Currently my hardware condition is VIM3L, software is Android12,
The Super.img I need to download now is 1.8G, but the super partition seen from the uboot is only about 1.8G, I configured the size of the super partition in boardConfig under the device, but it seems that the partition in the Uboot is actually valid.
I tried to use the Part command to modify it in the uboot stage (first set the environment variable super_size= 0x00380000, then use part size mmc 2 8 super_size), but it has no effect, can I tell you how to modify it?

你可以参考VIM3L-android-9.0-64bit的修改。如下：

@goenjoy
多谢多谢您的回复哈，
这个我之前也看到过，但是在dts中我没有找到类似partition的设备树呀，我这边再确认下，也可以麻烦您那边再帮忙确认下吗？谢谢

@goenjoy 您好，
我已确认这个上面是没有相关分区的实现的，请问下需要我自己去移植这部分代码吗？
或者有没有其他更方便的（代码量不多，但是涉及到的文件、范围比较大，需要时间去完成），比如uboot阶段的part命令是否可以被使用？或者还有其他的丢分可以控制分区吗？

@Stephen.dai 抱歉，AOSP没搞过。或者你百度下看看aosp具体是怎么实现的。
