Error connecting to the target: (Error -1170 @ 0x0) Unable to access the DAP.

Other Parts Discussed in Thread: TM4C1294NCPDT

Hi,

I made a custom board with TM4C1294NCPDT microcontroller and Black hawk XDS 100V2 debugger. when i trying to connect microcontroller with my CCSv6.1.3 compiler the error shows like this.

Error connecting to the target: (Error -1170 @ 0x0) Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 6.0.222.0).

Anybody tell how to rectify this and why this problem occur.

Reset pin pull up by 10K resistor 3.3V

Other connections are done as per standards.

Thanks in advance
