Jtagkey debug JN5168

[darlington]

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:

DEBUG ?=HW

DEBUG_PORT ?= UART0

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!

Hi Guillaume,

JTAG Debug is supported on the JN516x series of devices when using the latest JN-SW-4141 BeyondStduion for NXP

Could you take a look of this application note which provides a step-by-step guide

Let me know if you still have problems with the debug

Best Regards

Hello Mario,

Thank you for your answer.

I did it but I always got this error message (on my first post). I don't have the carrier and the expension board but my JN5168 works and I made a DIY expension board with the schematic on my first post (the same as yours thanks to the DR1222_Schematic_1V2 document).

have you got any idea?

Best regards,

Guillaume
