STC-USB Link1D仿真调试,KeilC251 debug模式进入函数,局部变量总是显示0x0000
现象:芯片:STC32G12K128仿真器:STC-USB Link1D
软件:keil C251
debug模式进入函数,call stack+local窗口:局部变量总是显示0x0000
测试过程:编写测试函数,small模式编译后,debug模式进入函数,call stack+local窗口:能看到函数局部变量数值变化
Xsmall模式编译后,debug模式进入函数,call stack+local窗口:局部变量总是显示0x0000
各位大咖帮忙看看怎么回事呀,多谢!

仿真步骤和设置参考此贴:用 STC-USB Link1D 硬件SWD仿真STC32 - https://www.stcaimcu.com/forum.php?mod=viewthread&tid=703&extra=page%3D1
没人给个解决办法吗?按楼上的仿真步骤和设置搞完还是看不到局部变量值,是和small模式有关吗?
