器件型号：TDA3XEVM 首次发布在这里、是 TI 全球的全新产品。 我正在使用 TDA3XEVM、并且使用最新的 CCS 版本为其中一个 ARM Cortex M4创建测试项目。 首先、我想让 Timer1中断工作。
我使用的链接器命令文件如下所示：
.if __TI_EABI_ASSEMBLER
.asg c_intIRQ, C_INTIRQ
.else
.asg _c_intIRQ, C_INTIRQ
.endif
.global _c_int00
.global _int_handler
;.global C_INTIRQ
;.global tim1_int
.sect ".intvecs"
B _c_int00 ; reset interrupt
.word 0 ; undefined instruction interrupt
.word 0 ; software interrupt
.word 0 ; abort (prefetch) interrupt
.word 0 ; abort (data) interrupt
.word 0 ; reserved
B _int_handler ; IRQ interrupt
;B tim1_int ; FIQ interrupt
以下是处理程序 FWiw：
__interrupt void int_handler(void)
{
int i = 0;
i = 9;
if(i == 10)
{
i = 9;
}
}
我在*。map 文件中生成了此文件：

我无法看到".intvecs"段在*。map 文件中的位置。 我正在使用编译器目录中的默认链接器命令文件- lnk.cmd。 我可以在这里找到：
C：\ti\ccs1040\ccs\tools\compiler\ti-cgt-arm_20.2.5.LTS \lib
另外、不确定在哪里可以查找信息、以了解某些处理程序需要放置在矢量表中的哪个位置。
因此、对于这种使用 CCS 及其工具的 TI 方案而言、这是一项非常新的工作。 希望通过创建一个简单的计时器中断例程(如微控制器类型的 C 应用)来更深入地了解这一点。
