TMS320DM6467T: C64XP: Error connecting to the target: (Error -1137 @ 0x0) Device is held in reset. Take the device out of reset, and retry the operation. (Emulation package 9.6.0.00172)

请问GEL文件中有ARM复位DSP核的语句吗？DSP核需要ARM核对其复位。如C:\ti\ccsv8\ccs_base\emulation\boards\evmdm6467\gel\davincihd1080p_arm.gel文件中的boot_dsp_from_arm

先运行arm gel文件中的boot_dsp_from_arm，再连dsp核。

c/ti/ccs1110/ccs/ccs_base/emulation/boards/evmdm6467/gel/davincihd1080p_arm.gel 里有boot_dsp_from_arm 的语句，我试着重新开了一个arm项目，在arm 926 上加载了 c/ti/ccs1110/ccs/ccs_base/emulation/boards/evmdm6467/gel/davincihd1080p_arm.gel， 显示了以下信息：

ARM926: Failed to remove the debug state from the target before disconnecting.  There may still be breakpoint op-codes embedded in program memory.  It is recommended that you reset the emulator before you connect and reload your program before you continue debugging

但之后回到dsp的那个项目debug还是报错：

C64XP: Error connecting to the target: (Error -1137 @ 0x0) Device is held in reset. Take the device out of reset, and retry the operation. (Emulation package 9.6.0.00172)

是我操作的问题吗？只要在arm的那个项目里debug就可以运行 boot_dsp_from_arm 了对吧？

看上面的截图里的报错信息，ARM核也报错不能连。如果之前是可以connect的话，建议联系一下板子厂家确认一下是不是硬件的问题。

那请问有没有这个held in reset 的问题有没有硬件复位的解决方法？比如给RST引脚输入低电平之类的？谢谢！

之前能connect，当时一直是报错与DDR2有关的一个错，然后才知道这个错和GEL文件没有导入有关。第二天在target connection 的 ccxml 里在DSP那个核的初始化脚本上选择了c/ti/ccs1110/ccs/ccs_base/emulation/boards/evmdm6467/gel 里的一个 dsp.gel 然后就开始报现在这个错了，就算从初始化脚本李去掉那个gel 也还是报这个错。可能和这个原因有关。另外第二天重新拔插了电源和仿真器，不知道有没有影响。

和这个帖子有点像：e2echina.ti.com/.../dm6467-dvevm-ccs-device-is-held-in-reset-take-the-device-out-of-reset-and-retry-the-operation

1. 如果恢复到"之前能connect“情况还是不能连接的话，应该不是gel文件的 问题。

2. "重新拔插了电源和仿真器"，如果不是带电插拔仿真器的话，应该不会损坏仿真器。

3. 帖子里是ARM核已经连上，DSP核处于held in reset状态，所以需要ARM gel文件去复位dsp核。但您目前的问题是ARM核都没连上。

建议先到target configuration file配置界面里点击"test connection"看一下仿真器是否正常？

test connection 的结果是正常的，仿真器应该没有坏：

重新开了一个arm 工程，load 了一个gel文件，现在debug时报错：

还是arm核没有连上的原因吗？请问有什么可能的解决办法吗？

看了一下，ARM968_0: File Loader: Verification failed: Target failed to write 0x80000800

应该和cmd的

DDR2:         o = 0x80000000  l = 0x20000000  /* 512MB of external DDR */

有关，

但重新开了一个dsp工程，依旧 held in reset。

是在gel文件里load .out文件了？之前成功的情况下，也是用了这个gel文件？

一般流程是在ccs里手动connect，然后手动load .out文件。

我是在这里加载gel文件的。

之前成功指的是什么？之前遇到的问题就是没有加载gel，无法把程序烧录到外部的DDR2  https://e2echina.ti.com/support/processors/f/processors-forum/217114/tms320dm6467t-c64xp-file-loader-verification-failed-values-at-address-0x80000800-do-not-match

load .out 是指debug吗？手动 connect 是指 test connection吗？
