TI中文支持网28335芯片加密后仿真器连不上了，
老是报错
Error connecting to the target:
(Error -1015 @ 0x0)
Device is not responding to the request. Device may be locked, or the debug probe connection may be unreliable. Unlock the device if possible (e.g. use wait in reset mode, and power-cycle the board). If error persists, confirm configuration and/or try more reliable JTAG settings (e.g. lower TCLK).
怎么解决呢
我怀疑是cmd文件配置问题，我的程序太大了，并且用了并口通讯的 用了zone6
求指导
我的flash.cmd文件配置如下

Hi，加密后debug时可能会出现仿真器连不上，尝试将芯片解密：boot引脚配置为check boot mode，连上仿真器，然后用on-chip flash工具unlock，擦除SectorA。

但是我程序需要加密呢，我用dsp2808平台的加密完全没问题呢，加密后也能连接上仿真器呢，就是28335发现有这个问题，

shuangyou mo：
Branch to check boot mode When initially debugging a device with the password locations in flash programmed (i.e., secured), the emulator takes some time to take control of the CPU. During this time, the CPU will start running and may execute an instruction that performs an access to a protected ECSL area. If this happens, the ECSL will trip and cause the emulator connection to be cut. Two solutions to this problem exist: – The first is to use the Wait-In-Reset emulation mode, which will hold the device in reset until the emulator takes control. The emulator must support this mode for this option. – The second option is to use the “Branch to check boot mode” boot option. This will sit in a loop and continuously poll the boot mode select pins. The user can select this boot mode and then exit this mode once the emulator is connected by re-mapping the PC to another address or by changing the boot mode selection pin to the desired boot mode
那我怎么配置Wait-In-Reset emulation mode, 这个模式呢

Seven Han：
配置Wait-In-Reset 需要拉低 GPIO34 ，
GPIO37 GPIO34 TRST Wait Mode 1 0 0
