Been playing with the LonganPi 3H H618 (just upgraded H616) but it has bt and wifi issues looking for anyone with similar issues. Bot Android TV image and Debian builds trying to figure out why. the Wifi and Bt modules test working but my builds are just not allowing. awsettingsmanager maybe?

@yixintai its the lpi-3h board it has the normal AIC8800 baked in but there is a second wifi module on host board. Really its a cool looking project but so underdeveloped that while I am looking for a corporate solution it may not fit needs due to ambiguous notes and docs. I just need to flesh out the ui in android and strip out some of the issues. I just do want to spend days creating configs if someone has a quick answer. As for Corprate or Hobbyist the answer is both. working on a corprate solution but also do a fair amount of teaching my kids haw to make cool stuff like robots powered by Ai but this project is for work. and yes I know an A133 type board would be best but the the dev boards for them are so limited and the sellers are not cool with sharing bsp with US devs. and I have allwinnertech account but everything is not user friendly. We have to mail in our NDAs and they make it really complicated for poeple who dont live mainland to develop. (I love them and hate them at same time) .

@zhuzhengjun003 在 请教关于longan SDK编译的问题 中说：

请教一下各位大佬，在使用longan SDK编译系统的时候，需要设置ARCH=arm吗？我一设置ARCH=arm，然后使用build.sh就会编译失败，ARCH设置为空就不会。如果不设置ARCH=arm，编译出来的系统在编译.ko模块的时候会报找不到asm/types.h，请问这个是什么原因啊？还望哪位大佬不吝赐教，小弟万分感谢

I have run in to this I assume you figured it out. it really depends in your chip and end use. if your boardconfig is correct and you are sure what toolchain you are using. I know my android build I was working on freaked me out because I noticed it started compiling RiscV and then swtiched to arm and I was scared it was going to fait and 2hours later if finished awesome. I always feel weird posting in english so here is a better translation. 此问题通常归结为预期的交叉编译环境与构建系统（或 SDK）的配置方式不匹配。

当您设置 ARCH=arm 时：
构建系统被强制进入 ARM 交叉编译模式。但是，Longan SDK 的构建脚本（如 build.sh）通常针对目标架构进行了预配置。强制 ARCH=arm 可能会破坏 SDK 的内置假设（甚至与预配置的工具链相冲突），从而导致编译错误。

当您将 ARCH 留空时：
构建系统默认为其自己的配置。这允许 build.sh 完成而不会出现错误，但在编译内核模块 (.ko) 时，构建过程无法找到 asm/types.h，因为尚未为 ARM 环境设置包含路径。在许多现代内核中，像 asm/types.h 这样的头文件要么被移动，要么被别名化（通常为 linux/types.h），因此如果模块的 makefile 已过时，也可能存在兼容性问题。

怎么办
依赖 SDK 的环境：
Longan SDK 可能已经针对 ARM 进行了配置。尝试不要通过手动设置 ARCH 来覆盖环境。相反，使用 SDK 提供的工具链和环境变量，以便正确设置所有路径和标志。

检查模块的构建设置：

确保内核模块的 makefile 使用正确的 ARM 包含路径和头文件位置。
如果您的目标内核已移动或删除 asm/types.h，请更新模块源以包含 linux/types.h 或使用适当的头文件。
验证交叉编译工具链：
如果必须设置 ARCH=arm，请仔细检查交叉编译工具链（通过 CROSS_COMPILE 和相关变量）是否定义正确。此处的不匹配可能会导致主系统构建失败。

查看 SDK 文档：
某些 SDK 存在一些怪癖，即某些变量是预先配置的。值得查看 Longan SDK 文档，看看是否有交叉编译内核模块的推荐做法。

摘要
如果 SDK 已经管理了 ARCH=arm，请不要手动设置它，因为这可能会导致设置冲突。
调整模块的构建配置，以便它找到 ARM 的正确头文件路径（或更新包含以匹配现代内核标准）。
如果需要覆盖默认值，请仔细检查工具链设置。
通过将模块的构建环境与 SDK 的配置保持一致，您应该可以避免 build.sh 中的编译失败和 .ko 模块中的头文件错误。

@lccaa saves the day!

@zhuzhengjun003 I have a lot of errors when trying to compile for LonganPi_3h SDK its buggy even though it says 22.04 is best I had to fix a lot of dependency issues. and I had janky mklinux.sh

@lac2189 I love this forum but I have not pulled anything except knowledge from here I will do better to participate.
