[参考译文] TMS320F280039：闪存设置代码至 RAM 模块构建失败

https://e2e.ti.com/support/microcontrollers/c2000-microcontrollers-group/c2000/f/c2000-microcontrollers-forum/1320967/tms320f280039-flash-setup-code-to-ram-module-build-fail

尊敬的 TI：

我正在创建一个新项目。

并且尝试 将时间关键代码和闪存设置代码复制到 RAM 时。 当我构建这个项目时、项目失败了。 故障信息在上方。

我按如下所示检查了 cmd 文件 F280039_flash_lnk.cmd。

   .TI.ramfunc      : LOAD = FLASH_BANK0_SEC1,
                      RUN = RAMLS0,
                      LOAD_START(RamfuncsLoadStart),
                      LOAD_SIZE(RamfuncsLoadSize),
                      LOAD_END(RamfuncsLoadEnd),
                      RUN_START(RamfuncsRunStart),
                      RUN_SIZE(RamfuncsRunSize),
                      RUN_END(RamfuncsRunEnd),
                      ALIGN(8)

我检查代码、 f28003x_globalprototypes.h 中有外部

extern Uint16 RamfuncsLoadStart;
extern Uint16 RamfuncsLoadEnd;
extern Uint16 RamfuncsLoadSize;
extern Uint16 RamfuncsRunStart;
extern Uint16 RamfuncsRunEnd;
extern Uint16 RamfuncsRunSize;

该文件包含在 f28003x_examples.h 中、f28003x_examples.h 包含在 f28003x_SYSCtrl.c 中。

我还尝试在 f28003x_sysctrl.c 或 main.c 中添加这些外部函数 ，或者在我使用 InitSysCtrl()的情况下，仍然无法成功构建。

请帮我解决这些问题。

谢谢。
