Dear Ms, Mr,


I'm developing a project on a JN5168 and I'd like to debug it with the Amontec JtagKey 2 but I have this issue when I launch the debug mode:

(JN-AN-1174 project)



jp3: JTAG protocol via USB/parallel port for Windows.

Version 1.6.3

Assuming debug_if's TAP has an IDCODE of 0x14951185.

Using 'Amontec Amontec JTAGkey-2 (556XNII6)' interface.

Enabling high speed ftdi mode.

Using JTAG clock of 15 MHz

Enabling UART not supported/required on this adapter.


In my makefile, I have:



and TRACE ?=1


I respected the application note to start the debug (debug configuration -> _hwdbg.elf ...)

And I also have the transistor on a special pin like this :


Can we debug on the JN5168? If yes, what could be my mistake?


Thank you!
