TMS320F28377D: 重新上电不能工作

不断电debug，可以运行。

但重启以后运行不了，删除部分变量以后，断电可以重启。cmd文件如下：

Green Deng：

你好，我觉得这个问题应该说明一下删除的哪些变量？

但是一般来说，仿真可以运行但flash不能运行的话跟变量应该关系不大，程序如果使用flash.cmd文件的话能正常仿真吗？

,

li liu：

我删除的是我自己定义的一些volatile uint16，int16，float32，int64等格式的数据。

我的float32和int64的数据有个几十个。

通过删除变量，控制ebss使用率不超过1024，就能正常重新上电运行。如果＞1024，就会异常。

现在很愁，整个问题严重影响了我们的项目进度，如果是377不够用，还要换芯片。

,

li liu：

仿真使用的flash.cmd, debug运行无异常。

,

li liu：

这些变量是我自己定义的。

volatile float32 f32X1Adc1Voltage = 0;

volatile int64 s64Adc1Voltage = 0;

类似的变量。

,

li liu：

不帮忙解决嘛？

,

Green Deng：

抱歉刚看到。

.ebss部分包含全局变量，文件级静态变量和函数级静态变量。照例说如果仿真能正常运行的话flash也没问题。

你看一下ram和flash的两个CMD文件中.ebss的划分大小是相同的吗？

另外，可以在CCS内使用View–>Memory Allocation 来查看内存使用情况。

也可以参考一下这个页面的说明：software-dl.ti.com/…/c2000_c28x-compiler-understanding-linking.html

,

jh chen：

发一下你编译后的map文件。另外，你可以把有些变量通过  DATA_SECTION的方式指定到其他的RAM。这种一般是有些程序没有下载到flash，只是下载到ram，所以仿真时可以运行，但是脱离仿真器之后就运行异常了。
