今天板子刚到，新建的第一个工程就报错了。

.\Objects\cse.sct(7): error: L6236E: No section matches selector - no section to be FIRST/LAST.

网上查了一下说什么启动文件没添加，可是他们都没说在哪添加启动文件，我第一次搞这个我也不知道。

这时我在stackoverflow里搜到了这个问题。

题主遇到的问题和我遇到的一样，然后下边有答主这样说：

There is no 'FIRST' object in your source code. Your scatter file likely looks something like:

LR_IROM1 0x08000000 0x00040000 { ; load region size_region ER_IROM1 0x08000000 0x00040000 { ; load address = execution address *.o (RESET, +First) *(InRoot$$Sections) .ANY (+RO) } RW_IRAM1 0x20000000 0x0000A000 { ; RW data .ANY (+RW +ZI) }

The _FIRST object that the linker wants to put into the image is the area called RESET. You do not have a RESET region in your code. Add something along the lines of

AREA RESET, DATA, READONLY

to your assembly file where you want execution to begin.

Create a project with the startup file and look for the AREA RESET ..... declaration and copy that.

For Cortex it looks like:

AREA RESET, DATA, READONLY EXPORT __Vectors EXPORT __Vectors_End EXPORT __Vectors_Size__Vectors DCD __initial_sp ; Top of Stack DCD Reset_Handler ; Reset Handler DCD NMI_Handler ; NMI Handler DCD HardFault_Handler ; Hard Fault Handler DCD MemManage_Handler ; MPU Fault Handler DCD BusFault_Handler ; Bus Fault Handler DCD UsageFault_Handler ; Usage Fault Handler DCD 0

Each of those handlers needs to be declared, but you can just add the stack pointer and reset handler to get started.

我是看到这一段代码在startup里边，把这个模块一添加，然后就好了。

也就是添加 AREA RESET, DATA, READONLY 这一句到启动文件对应的位置。
