I think the raspberry version and the sdk-Lib version are different. The raspberry pi4 version of my A1 is arm7l(arm32). But sdk3.3 lib have only arm64 version.

How can I solve this problem?

I meet the some question,but if you want to run the example, you can run it in the folder /build,such as example_walk. If you want to run the code write by youself, you should compile you code in upper bord. the upper board is on the back of you dog. 翻译如下：我遇到了和你一样问题，如果你你只是想运行例子，你可以去/build文件夹，直接运行example_walk文件。如果你是想编译运行自己的代码，你应该在upper-board上进行编译，upper-board在你狗的后面。
