stm32 :No section matches selector - no section to be FIRST/LAST

1) ..\OBJ\(文件名).sct(7): error: L6236E: No section matches selector - no section to be FIRST/LAST.

解决：

错误定位到文件 (文件名).sct:

; *************************************************************

LR_IROM1 0x08000000 0x00080000 { ; load region size_region

ER_IROM1 0x08000000 0x00080000 { ; load address = execution address

*.o (RESET, +First) ;====================>错误定位

*(InRoot$$Sections)

.ANY (+RO)

}

RW_IRAM1 0x20000000 0x0000C000 { ; RW data

.ANY (+RW +ZI)

}

}

分析:

(文件名).sct:文件对程序存储在rom的位置做了指定.在开发环境Keil uVision3中,可以在这里选择位置:



解决:

没有添加startup_stm32f10x_md.s 文件，或者该文件选择错误

在keil中 添加文件时，默认的是*.C文件 ，这样.s的文件就添加不上，所以会报错。 应该将文件类型选为*.* 就能全部添加了

startup_stm32f10x_md.s文件的作用：

* Description : STM32F10x High Density Devices vector table for MDK-ARM

;* toolchain.

;* This module performs:

;* - Set the initial SP

;* - Set the initial PC == Reset_Handler

;* - Set the vector table entries with the exceptions ISR address

;* - Configure the clock system and also configure the external

;* SRAM mounted on STM3210E-EVAL board to be used as data

;* memory (optional, to be enabled by user)

;* - Branches to __main in the C library (which eventually

;* calls main()).

;* After Reset the CortexM3 processor is in Thread mode,

;* priority is Privileged, and the Stack is set to Main.
