TMS320F28377D: Flash api

程序为Bootloader+应用层程序，单核。Bootloader区域为FLASH A-D，应用层区域为Flash E-K, 应用层中掉电数据保存区域为Flash L-N（通过CAN/SCI通信及Flash API完成在线数据更新）。

目前问题如下：当通过调试器下载并直接运行，观测Flash L-N区域和通信反馈数据，可以完成正常的Erase、Write等功能。拔掉调试器重新上电或通过通信及wdg配合完成复位后，flash相关的Erase\Write命令均执行不成功。

是否与Bootloader到App的跳转有关，是否可能是编译器优化了部分代码，如while(Fapi_checkFsmForReady() != Fapi_Status_FsmReady){}语句等为进行判断，是否还有其他可能原因。

目前已经做过的测试如下：

1.bootloader程序中删除Flash驱动包的初始化，直接通过asm(" LB 0x088000")跳转进App程序，由App重新完成系统初始化等，问题依然存在。

2.取消Bootloaer程序，更改CMD问题，仅存在应用层程序，问题依然存在。

3.通过变量取值如res=Fapi_checkFsmForReady(),通过变量判断，排除编译器优化干扰等，问题依然存在。

Green Deng：

你好，看了一下你的问题，有个点不知道你注意到没有，就是FlashAPI函数必须在ram中运行。

由此有可能导致你的程序在线调试的时候能正常运行，但烧写到flash之后就会无法正常运行了。

,

Bo XU：

在线调试时候也是通过FlashAPI函数的，观察RAMD1和FLASHG区域应该是重定位到RAM成功的，难道复位后有问题？

初始化：

memcpy(&RamfuncsRunStart, &RamfuncsLoadStart, (size_t)&RamfuncsLoadSize); memcpy(&RamfuncsFapiRunStart, &RamfuncsFapiLoadStart, (size_t)&RamfuncsFapiLoadSize);

CMD文件： .TI.ramfuncFapi : { –library=../F2837xD_flashapi/lib/F021_API_F2837xD_FPU32.lib } LOAD = FLASHG, RUN = RAMD1, RUN_START(_RamfuncsFapiRunStart), LOAD_START(_RamfuncsFapiLoadStart), LOAD_SIZE(_RamfuncsFapiLoadSize), PAGE = 0, ALIGN(4)

,

Bo XU：

连着调试器也是整个程序烧写到FLASH里运行的，不是在RAM中运行的

,

Green Deng：

这个问题我会咨询一下其他工程师之后回复你，还请耐心等待。

,

Bo XU：

一些补充信息：

1.CCS版本Version: 11.0.0.00012、包版本C2000Ware_4_00_00_00

2.将Bootloader程序删除，只保留应用层程序,并更改CMD文件，问题依然存在，应该与Bootloader跳转等没有关系

3.无论是连接下载器还是未连接下载器，RAM的重映射区域用通信读取出来，应该是均映射成功的

4.RAM重映射代码如下：

#ifdef _FLASH//// Copy time critical code and flash setup code to RAM. This includes the// following functions: InitFlash();//// The RamfuncsLoadStart, RamfuncsLoadSize, and RamfuncsRunStart symbols// are created by the linker. Refer to the device .cmd file.//memcpy(&RamfuncsRunStart,&RamfuncsLoadStart,(size_t)&RamfuncsLoadSize);memcpy(&RamfuncsFapiRunStart,&RamfuncsFapiLoadStart, (size_t)&RamfuncsFapiLoadSize);memcpy(&RamfuncsFpuRunStart,&RamfuncsFpuLoadStart,(size_t)&RamfuncsFpuLoadSize);memcpy(&RamfuncsUserRunStart,&RamfuncsUserLoadStart, (size_t)&RamfuncsUserLoadSize);//// Call Flash Initialization to setup flash waitstates. This function must// reside in RAM.//Flash_initModule(FLASH0CTRL_BASE, FLASH0ECC_BASE, DEVICE_FLASH_WAITSTATES);
#endif

，通信接收数据后，直接调用相关函数完成Erase\Write操作，然后通过通信回复返回值。

6.TIC2000调用API函数Flash擦除片上FLASH失败_量子力学和生命科学的博客-CSDN博客，这个帖子中的问题与我遇到的及其相似，但根本原因好像不同。

7.连接调试器时可正常工作，在未连接调试器时，如手动发动Write命令多次，会造成单片机Wdg复位,复位源已确认，Wdg工作在window窗口模式。
