在调试F28M35时候,M3的程序能够正常下载到flash上,而C28不能下载,ccs 6提示的错误信息为:
C28xx_0: Loader: One or more sections of your program falls into a memory region that is not writable. These regions will not actually be written to the target. Check your linker configuration and/or memory map.
C28xx_0: File Loader: Verification failed: Values at address 0x000000000013E000 do not match Please verify target memory and memory map.
C28xx_0: GEL: File: C:\Users\MQinDong\Documents\TIccs\Projects\MMC\MMC_v2\MMC_C28_v2\FLASH\MMC_C28_v2.out: a data verification error occurred, file load failed.
我用的cmd文件是controlSUITE提供的最新版本(v206):F28M35x_headers/cmd/F28M35x_Headers_nonBIOS.cmd和F28M35x_common\cmd\F28M35H52C1_c28.cmd.
其中,F28M35H52C1_c28.cmd如下。

我之后又将上述F28M35H52C1_c28.cmd替换为28M35H52C1_RAM_lnk_c28,就可以下载到RAM调试了,有谁遇到相同问题?我估计是cmd文件的问题,但不知道哪儿出错。

Dong,
检查下是否超出了FLASHA段的大小。

没有超出FLASHA的大小,因为map文件显示 FLASHA unused memory还有空间。我也尝试将代码放到更大的FLASH段,仍然出现相同问题。

我也试过了,仍然出现相同的问题。
我测试的最小例程是controlSUITE里面的..\ti\controlSUITE\device_support\f28m35x\v206\F28M35x_examples_Dual\blinky目录下的例程。我也测试了controlSUITE以前版本的同名例程,v203~v206都测试了,都是相同问题。
有人说是仿真器或者芯片的原因,不知道是不是有这样的可能。如果是仿真器的原因,但是M3的代码是可以用我用的仿真器烧写到 m3 flash运行的,并且C28 core也可以在RAM里面运行,且在CCS 调试界面相关的调试操作也很正常,比如断点、停止、运行等操作,所以我觉得我的仿真器是正常的。同理,我觉得芯片出问题的可能性也较小。我现在也没办法,暂时只能让代码在RAM运行。

不知道TI ccs有没有flash擦除工具?我想尝试下看能不能擦除C28 的FLASH,或者能够实现相同功能的途径也行

Dong,
连接上目标板之后,在tools中有一个在线Flash烧写插件的,直接点击打开就可以进行擦除等操作。

Martin Yu,
我现在是点击DEBUG那个蜘蛛图标进入DEBUG 界面的,意味着此时我的代码已经烧写到C28的RAM里面了。然后我再点击tools/On-chip flash,然后点击图1所示的erase flash,CCS 提示错误,如图2所示。但是此时我的仿真器是连上的,因为如果此时我点击运行,我的板子是正常运行的(代码是烧写在RAM里面运行的)。我这种情况是否意味着我的芯片的FLASH 出了问题。

经过测试,是我的芯片的C28 FLASH损坏了。
