TMS320F28016的JTAG连接不上的问题

在与目标板连接的时候出现jtag连上后,不能与DSP内核通信的问题,目标板一直处于复位状态中。错误提示如下:

Failed Software Reset: Error 0x00000024/-1137 Error during: Register, Execution,   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。

请确认你到底是否连接成功?

同时如上面信息提示,检查EMU0/1的电平状态,他们的硬件连接是什么样的呢?正常接法应该分别上拉4.7k电阻。

建议也可更换其它仿真器测试。

Jones Chen:

1. 您的EMU0,EMU1是否都是用4,7K电阻上拉到3.3V?

2. Reset引脚是什么状态?

3. 有4个引脚来配置要Boot到什么位置,您这四个引脚是否都是高电平?只有是高电平,才能Boot 到Flash中。

4. 我曾经写过一个文档,可以供你参考。但附件太大,明天会有专人回复。
