I try to connect to a custom board using P&E multilink tool and P&E GDB server for Kinetis. My MCU is MK60DN512VMD10.
I get the error message as follows:
Server running on 127.0.0.1:7224
P&E Interface detected - Flash Version 9.33
Can not enter background mode .
Unable to initialize PEDebug.
PE-ERROR: Failed to Initialize Target
I tried to change device name, additional options (SWD mode on/off, erase on connect on/off) and debug speed, but still the same message. When I measure on the JTAG with an oscilloscope, I detect activity on the reset, TCK, TMS and TDI lines. The levels look correct. But there is no activity on TDO!
I don't have an external oscillator in my design. The EZP_CS_b pin is not connected either. Could any of this be the problem?
