TI中文支持网近日小弟在开发28335的板子，新板子回来之后用CCS进行调试，可以代码总是下不进去。分别用了CCS4.0和CCS4.2两个软件进行调试。
软件给出的结果都不一样，CCS4.0给出的提示是这样的：
It appears that the target is being held in reset. This may be
due to Wait-In-Reset (WIR) configuration set by the EMU0=0
and EMU1=1 pin settings. If this is the case, DISCONNECT
all CONNECTED devices including icepick and then select
RETRY to clear the WIR configuration.
If this is a multi-core system, the master CPU may not be
releasing the DSP/MCU from reset. Please check your
configuration in CC_setup and/or your GEL file to ensure that
nothing is blocking the DSP/MCU from being released from reset
然后我检查了EMU0和EMU1的电平都是高电平，没有问题。
用CCS4.2调试的结果是这样的：
C28xx: Flash Programmer: Warning: The configured device (TMS320F28335), does not match the detected device (). Flash Programming operations could be affected. Please consider modifying your target configuration file.
C28xx: Failed Software Reset: (Error -1137 @ 0x0) Device is held in reset. Take the device out of reset, and retry the operation. (Release 5.0.429.0)

Cannot write to target
C28xx: Error: (Error -1135 @ 0x3FF9CE) The emulator reported an error. Confirm emulator configuration and connections, reset the emulator, and retry the operation. (Release 5.0.429.0)
DSP的XRS管脚电平也是高电平，没有复位，所以这个应该没问题。
所以现在我也不知道问题出在哪里了，求各位高人指点，给点思路，感激不尽啊啊啊！！！
先谢谢各位看帖的前辈了。

您好！我想问问代码下载不进去还是CCS连接不到目标板上
如果是连接不上 请检查硬件仿真器是否支持CCS对应的版本 仿真器驱动是否安装到CCS同一目录
如果连接上只是下载时出问题 就有些不理解了 个人觉得应该是CCS安装问题了

确认芯片供电有没问题，JTAG口接线。
另外用最新的CCS, 配置好正确的仿真器，芯片。

您好，我也是这样的问题。可以连接上，但是运行时系统一直是“0 <symbol is not available> 0x3ff9ce”；断开连接以后，再次想要连接，就会报错，错误内容和你的一样。我自己测量了我的芯片MAX811T的2脚（RESET脚），确实一直是低电平。

你要检测一下你芯片的供电电源是否在手册要求的范围之内，然后软件的话，烧写一个controlSUITE里面的标准例程来做测试。
