RAM大小配置

你好，
 
 
 我不确定你的问题是什么以及你实际想要实现什么，但是在你报告的链接器文件部分中，你告诉链接器你的变量将从0x100开始并且不必超过625字节（0x271） ）。
 根据这一点，只有当你的变量使用超过625个字节时才会报告错误（在第1页中，但此时不需要进入这些细节......），无论堆栈如何。
 堆栈本身将从0x3FFF开始向后增长：如果它增长太多（注意编译器的堆栈大小预测非常准确，但是特殊情况可能是错误的，因此无法保证）它会覆盖一些全局变量，在运行时导致各种奇怪的行为（很可能是应用程序崩溃）（这不是你可以在编译/链接时检查的东西）
 
 希望能帮助到你。

Hello,


I'm not sure what your question is and what you are actually trying to achieve, but in the linker file part that you have reported you are telling the linker that your variables will start at 0x100 and will not have to exceed 625 bytes (0x271).
According to this, the linker will report an error only if your variables use more than 625 bytes (in page1, but no need to go into these details at this point..), regardless of the stack.
The stack itself will start at 0x3FFF and grow backward: if it grows too much (note that the stack size prediction by the compiler is pretty accurate, but can be wrong is special cases, and thus is not guaranteed) it will overwrite some global variables, resulting in all kinds of strange behaviours (most likely an application crash) at run time (that's not something that you can check at compile/link time)

Hope it helps.

Luca

嗨卢卡，
 
 
我将RAM的结束值更改为0x300，但lkf文件始终显示0x271
你知道STM8如何将RAM扩展到0x300
非常感谢

Hi Luca,


I changed end value of the RAM to 0x300 but the lkf file  always show 0x271
Do you know how STM8 extend RAM to 0x300
Many Thanks
