大家好,我们在用ccs编写程序后,利用工具对程序进行优化后,程序有时候不能正常运行,运行之后也无法查看寄存器的值和变量的值,想请教一下大家这是什么原因导致的,有没有什么解决方案

user6005420 说:利用工具对程序进行优化后,程序有时候不能正常运行,
请问您是使用的什么工具进行优化? 能否详细说明下?现在使用的是什么芯片呢?
您现在是把优化关掉了?您可以使用
Optimizer_Assistant
https://processors.wiki.ti.com/index.php/Optimizer_Assistant
另外您也可以尝试使用CCS提供的代码剖析工具Profile可以统计显示出程序中各个重要段和函数的运行时间,找出运算量较大的程序段,优化这些程序段,对于提高算法的性能有巨大影响。
优化没有关,我现在遇到的问题是,代码量比较大,不优化的话flash不够用,想要通过优化来钱少代码量,但是优化之后程序无法正常运行

你好,这个链接我们之前就看过了,没什么帮助,你那边能不能帮忙看一下cmd文件,还有没有什么别的解决方案
您好,这个工程不太方便直接发给您,这回死我们公司最近做的的项目,包含了部分公司机密
