求LPC11xx IAR启动文件 [复制链接]

小弟想把keil mdk下的LPC1114工程移植到IAR for ARM下，目前来说已经成了一个半成品，在keil下工程调试时可以在IDE中复位MCU，然后从头开始运行。但这个功能在IAR下不知道为何就是无法正常使用，如果点击回到程序开头那个按钮，程序依然不会回去到main函数开始处，而是继续保留在当前执行的地方。我怀疑我的启动文件有问题，大家知道在IAR下可以使用c文件编写启动文件也可以使用汇编文件编写启动文件，我自己参照其他的厂商的芯片编写了一个c语言版本的启动文件，如下，可能存在问题。但是不知道问题在哪？哪位大侠知道LPC11xx系列片子的IAR启动文件（.s 或.c都可以，只要能正常使用）能不能帮我贴一份出来，感激不尽！
