工程师ccs3.3的，现在移植到ccs5.2修改了一些报错能成功编译。
1 在main函数开头加入断点。
2 连接仿真器，加载编译出来的6455.out文件后自动运行了。
3 这时候并没有跑到main函数断点出。
4 点击暂停按钮，单步执行，一直在汇编里跑进不了main函数断点。
请问下这个有人遇到过没？是ccs5.2配置问题还是代码问题呢？感激不尽！
Nancy Wang：
在ccs3.3中运行是可以的吗？
ccs->run->debug configuration是否设置为main函数处停下，具体参考以下链接：
software-dl.ti.com/…/ccs_debug-main.html
,
wang yanping：
debug configuration是否设置为main的，请知悉！
,
wang yanping：
debug configuration是设置为main，请知悉！还有其它原因吗？
,
Nancy Wang：
能跑到程序的入口点c_int00吗？
,
wang yanping：
跑不到啊；暂停后，单步执行，一直在汇编B0C1D6FC地址跑，但是我们的norflash是接到EMIFA CE3地址是B000 0000 – B07F FFFF，像是程序跑飞了。
,
wang yanping：
加载.out的时候，提示earlier errors prevent reading of target memory at memory B0000000等，加载后运行，暂停，单步执行现在又跑到e0001840了
,
Nancy Wang：
cmd文件贴出来看一下，加大堆栈试一下。
调试界面的截图请贴出来。

wang yanping：
请问下如何增加堆栈呢？谢谢
,
Nancy Wang：
您是直接将代码load到flash中的吗？在GEL文件中配置的读写时序？能否直接将代码放到内部ram或者DDR上跑了试一下。
堆栈可以直接在cmd中配heap和stack。
,
wang yanping：
我不太清楚是不是直接load到flash了，哪儿看出直接load到flash了。
,
wang yanping：
GEL用的系统自带的DSK6455.gel
,
wang yanping：
如何配置成load到RAM运行。具体在CMD怎么加堆栈呢，没改过，谢谢
,
Nancy Wang：
section部分指向IRAM。例如修改 .text > IRAM。
SECTIONS{ .boot_load : > FLASHBOOT
.text : load = FLASHREST, run = IRAM .const : load = FLASHREST, run = IRAM .printf : load = FLASHREST, run = IRAM .cinit > FLASHREST .pinit > FLASHREST .switch > FLASHREST .binit > FLASHREST
.bss > IRAM .far > IRAM .data > IRAM .cio > IRAM}
,
wang yanping：
我已经按照你说的把myc6455.cmd的全部改成IRAM了但是load的时候还是跑到B0000000 emifa ce3的地址去了

,
wang yanping：
dsk6455cdb.txt这是cdb文件，由于后缀cdb不能上传，只能改成txt
,
wang yanping：
global STACKSIZE :: 10240 {
inst iHeapSize :: 0x8000 {
修改堆栈大小是不是cdb文件的以上2个地方？
,
Nancy Wang：
cbd文件早期ccs上的文件吗？现在已经不用了。都是在cmd文件中配置。
例如：
-stack 0x1000-heap 0x2000
,
wang yanping：
cdb文件是CCS3.3工程上面的；cmd文件是cdb生成的，所以只能在cdb改堆栈大小。
,
wang yanping：
从dsk6455cfg.cmd文件最后面内容看stack=0x2800 heap=0x4000，这个还要改大吗？
,
wang yanping：
现在load到emifa的nor flash，运行进不了main函数，昨天改了load到IRAM不起作用是哪儿的问题呢？
,
Nancy Wang：
在ccs3.3中是可以正常运行的是吗？导入例程试一下是否可以正常load。
以下链接有一个从ccs3.3移植到新版ccs的文档也仔细阅读看一下。
https://www.ti.com.cn/cn/lit/an/zhcaa58a/zhcaa58a.pdf
堆栈可以尝试加大看一下有没有帮助。
,
wang yanping：
CCS3.3是好的；例程在哪下载呢？；堆栈已经分别加大到0x100000 0x8000了是一样的效果；移植应该没问题都编译过了
,
Nancy Wang：
参考附件中的例子。
6888.dsk6455_v2.zip
,
wang yanping：
问题已经解决，配置成IRAM运行就可以了。
