    • XR806系统选择问题咨询（2023年8月）

      很长时间没有用这块板子了，最近又需要用起来。想咨询下大家这么几个问题：

      1. FreeRTOS需要在全志客户服务平台下载，我属于学生开发者没发完成资质认证怎么办？
      2. 21年左右接触过XR806的鸿蒙开发，今天在查看开发者论坛的时候看到了XR806 SDK的相关内容，这个SDK和鸿蒙和FreeRTOS的关系是什么呢？

      如法炮制把其他出错行搞了下，成功编译

      @tigger @YuzukiTsuru 大佬们，我用的官网提供的链接(如下说明)，下载下来是一个叫riscv64-linux-x86_64-20210329.tar.gz的工具

      如果您只是想先试玩一下，还没下载完整源码，可以单独下载编译工具链：

      另外我检查了开发板的Glibc版本发现就是2.29啊，看不懂了😢

      环境搭建

      1. WSL2 Ubuntu 20.04 LTS开发环境搭建

      感觉和正常的Ubuntu环境配置(220119发现链接失效，我从提交记录里找到了当时参考的那一篇)没啥区别，区别有以下几个

      a.在 安装必要的库和工具的时候把libc6-dev-amd64替换为libc6-dev就成，这个方法参考github上边wsl给的遇到E: Unable to locate package libc6-dev-amd64的解决方案

      b.我没装LLVM也可以烧录
