Dear SEGGER moderator:

Hello, I am working with the evaluation board ADuC7030/32/33 from Analog Devices.

I have been using it for a couple of weeks but now I receive a message from the JTAG that it is unable to halt de ARM7 core.

I have read the post: unable to halt ARM core and this from Oliver: Software: Unable to halt arm core on STR7.

My problem is very similar but for other ARM core.

I have tested everthing reported in the post but I can execute my code.

The J-Ling log is this (note that I connect the EVAL Board in the middle of the test)

Once I change the ADuc7033 by desoldering it and installing a new one. I think that the new one had its on-chip factory firmware that supports JTAG reprogramming ok, and everything was OK.

But now, erasing and downloading the blinking Keil example [C source file ] in the EVAL Board [SCH+PCB ] is not possible.

Is there any way I can re-program the ARM micro without resoldering a new microcontroller.


Thanks in advance.
