TMS320F280049: 使用Flash运行程序时，只有在插着探针（XDS100V2）时才能正常运行，拔下后芯片停止运行，重新插上又能恢复

Part Number: TMS320F280049
Other Parts Discussed in Thread: C2000WARE

我正在学习TMS320F280094，现在运行程序时（RAM与Flash都一样），只有在插着探针（XDS100V2）时才能正常运行，拔下后芯片就会停止运行（板子插着探针时，电流有0.09A，拔下后只有0.02A），重新插上后又能恢复正常运行，此时并没有进CCS的调试模式。
若断电后再上电，或者按下复位键，则需要重新烧录后才能正常工作。
选择的是运行方式选项来烧录。

已经配置为Flash模式（不过RAM模式的问题也一样），并添加宏定义

这是我的InitSysCtrl函数

硬件方面，根据手册配置了BOOT引脚为闪存模式（两组排针均处于断路状态）

晶振方面，插着探针时用示波器测量，测得正常的20MHz正弦波，拔下探针后波形消失（此时探针与我的F280049板子并没有断电，若探针断电后再上电，即使插回我的板子仍然无法让芯片恢复正常工作）

已经收到了您的案例，调查需要些时间，感谢您的耐心等待。

您好

jiahao huang 说：
若断电后再上电，或者按下复位键，则需要重新烧录后才能正常工作。
选择的是运行方式选项来烧录。

这听起来好像正在使用 RAM、而不是闪存。

您能否仔细检查您正在使用的链接器 CMD 文件？

我的CMD文件已经放在文章中，使用flash时，我屏蔽了f28004x_headers_bios.cmd与28004x_generic_ram_lnk.cmd两个文件，上面的内容是我在CCS12.4.0测试的，在CCS20.2.0测试时，我使用了示例工程gpio_ex2_toggle，问题依旧。使用晶振时，插着探针能够测到正常的20M正弦波形，拔下探针波形消失，使用内部振荡器也是如此，拔下探针芯片停止工作，掉电流，重新插上探针又能恢复。请问这是否是我CCS设置的问题？

您好

您的探头的电容似乎很可能会影响振荡器。如果除非连接了探头、否则振荡器不工作、您需要添加一些额外的电容。

通常建议使用 XCLKOUT 测量时钟频率。
