根据以下网盘链接获取Tina-sdk V2.0源码

• 获取Tina-sdk V2.0源码 百度网盘获取地址 链接：https://pan.baidu.com/s/13uKlqDXImmMl9cgKc41tZg?pwd=qcw7 提取码：qcw7 压缩包路径在 Tina-SDK_DevelopLearningKits-V1/DongshanNezhaSTU-TinaV2.0-SDK 拷贝进Ubuntu系统内，并进行解压缩,解压命令在README里面

不修改配置情况下，可以正常编译并在DongshanPi-D1s上正常运行，
但是，添加gdb/gdb server模块后报BFD does not support target riscv64-unknown-linux-gnu错误，具体如下：

checking whether snprintf is declared... yes
checking whether vsnprintf is declared... yes
checking whether strnlen is declared... yes
checking linker --as-needed support... yes
checking for cos in -lm... yes
*** BFD does not support target riscv64-unknown-linux-gnu.
*** Look in bfd/config.bfd for supported targets.

根据网络上搜索的，更新了虚拟机的binutils到最新版也没作用。
交叉编译器用的是如下仓库中的：

https://gitee.com/weidongshan/eLinuxCore_dongshannezhastu.git
cd  eLinuxCore_dongshannezhastu
git submodule update  --init --recursive
