box源码
‘壹’ 只使用busybox源码和一个老版本的linux内核源码，如何搭建一个能够启动的系统
busybox和内核比较独立, 可以用buildroot等生成rootfs
‘贰’ 这段js代码，我想点击按钮，id为box的div中间随机出现红色小方块。哪里出错了

C++ ASM
‘肆’ spline toolbox怎么查看源码
如果是系统自带的，你可以直接用，如果是外部的或者是自编的你需要先把文件夹拷贝到tools文件夹下，再设置路径。

‘玖’ 新手求助 box虚拟机如何编译vboxdrv内核
先启动开发机。然后启动目标机，开机时按Esc建选择有kgdb的内核启动，等待一下后启动过程会暂停并提示等待远程gdb调试，这时切换到开发机并进入到源码目录下，运行
gdb ./vmlinux
gdb启动后，使用以下命令设置波特率和调试终端：
(gdb)set remotebaud 115200
(gdb)target remote /dev/ttyS0
