问题如下：

DSP在从_C_int00运行的时候，都进行了什么操作啊？我试着跟踪了一下程序，但是没有看明白

解答如下：

1.Sets up the stack and the secondary stack.
2.Initializes global variables by copying the data from the initialization tables in the .cinit section to the storage allocated for the variables in the .bss section. If you are initializing variables at load time (-cr option), a loader performs this step before the program runs (it is not performed by the boot routine). Automatic Initialization of Variables provides more information.
3.Calls the function main to run the C/C++ program.
