自己做了一块dsp28016的最小系统,测得电压、时钟信号都是正常的,用的仿真器是spectrum digital XDS510LC usb
每次连接报错是:
Error connecting to the target:
Error 0x80000200/-1135
Fatal Error during: OCS,
Unrecoverable emulation errorI/O Port = 510
Board Name: F2808 XDS510USB Emulator
Cpu Name: cpu_0
Abort: Close Code Composer Studio.
Retry: Try to connect to the target again.
Cancel: Remain disconnected from the target
Diagnostic: Run diagnostic utility.
接上仿真器后,测JTAG的TRST一直为低,TCK没有脉,TMS为3.28V。
我查了硬件没发现什么问题
请高手们指点是什么原因? |
