Debug External Processors with USBDM

and Freedom BoardPosted on April 27, 2013

Teaching at a university means to work in a very special environment. What students love is

Open Source: because it allows them to see things and learn from the technology. The

other thing is: students have a low budgets, so they appreciate if they can use inexpensive or

low-cost hardware and software. The FRDM-KL25ZFreedom board for sure meets that low

price, and no extra programming device needed.

Now they are building their own boards, and they wish to program and debug it. They can

borrow the Segger J-Linksand P&E Multilinkswe have available at the university. But why not

use the Freedom board as hobby debug and programming solution? As explored in Using

the Freedom Board as SWD Programmer, they can use the default factory installed

OpenSDA to program another microcontroller of same type. But not to debug it.

While writing the Using the Freedom Board as SWD Programmer article, I was looking into

USBDM. USBDM has added in January 2013 support for OpenSDA. But at that time, it wassomehow not working for me, and I had not enough time to find out what the problem was.

Time to get that fixed. Good news: With help and tips from the USBDM community, I have it

finally working

USBDMis a free open source (GPLv2) debugging/programming interface for a range of

Freescale microntrollers.

Note: USBDM is *not* OSBDM. OSBDM (or OSJTAG) is an older free

deb!!in! interfa"e #resent on $an% of t&e'rees"ale Toer Boards.

It currently supports CodeWarrior and CodeSourcery Eclipse. With it, I wanted to overcome

the OpenSDA limitation and using it as general purpose debug/programming device with

CodeWarrior for MCU10.3.

OpenSDA USBDM Firmware Installation

For OpenSDA, I need a special firmware. I did download the USBDM_OpenSDA firmware zip

file:

Then updated the firmware on the Freedom board, following the instructions in the

OpenSDA.txt in the archive. After that, the device should enumerate properly as USBDM

Using USBDM as SWD Debugging Probe (FRDM-KL25Z to FRDM-KL25Z)

To use USBDM on FRDM-KL25Z to debug another external processor, following is needed

Having a 10pin ARM Cortex Debug (SWD) header populated on two boards1.

Connecting the two boards with a 10pin flat cable2.

Having J11 cut on the master board to disconnect the SWD clock from the resident

processor

3.

No change needed on the slave board to be debugged.4.

And indeed: this worked :-): Im able to use my USBDM to debug the other KL25Z Freedomboard:

Debugging the FRDM-K20D50Mwith the FRDM-KL25Z the same way as debugging the the

FRDM-KL25Z above:

As above, the master boards needs to have the J11 trace disconnected.

Using FRDM-KL05Z to Debug an External Board

Next one is the FRDM-KL05Z. However, this did not work out of the box. Until I have found

this post in the Freescale Forum: The problem is a wrong wiring to the J6 header: the

OpenSDA signal from U4 goes to pin1 of J6, and this pin1 goes as well to the KL05Z. This

means that it is not possible to disconnect the OpenSDA from the KL05Z . The solution is

to cut a trace and connect it to either pin 4 of J1 (SWD header) or to pin2 of J1. I did the

second solution.

First, I need to cut the J6 trace:

For the next step, a magnifying glass or a microscope is a good thing, plus some good

soldering skills :-): I need to re-route the Pin11 from U4 to Pin2 of J6. For this I need to cut

the trace just before the via hole to the KL05Z:

After that, install a wire to route the Pin11 of U4 to Pin2 of J6:

OpenSDA power and SWD clock:

But this did not help .

However, with the P&E Multilink Im still able to debug that board with the SWD debug header

. So there are definitely good reasons to use a probe like this: to recover from cases

where USBDM cannot help. As always: as second source and backup is what an engineer

always needs.

The other problem I was running into was this one with a 60 KByte application:

boards. So far I just have explored OpenSDA Freedom boards, but it should support boards

and microcontroller beyond that: I can now download *and* debug other microcontroller with

the Freedom board . What Im missing with USBDM is the USB CDC support which the

original OpenSDA provides(or I have not seen how to enable that).

While professional solutions like P&E and Segger worked for me out of the box, I had to

invest time to get USBDM up and running. After that, it was working nicely. Spending that

extra time is like with any other Open Source projects I did or used: I trade in time for less

costs, or to learn new things on return. I hope that this article saves you some time and is

useful for you.

Many thanks and kudos to pgo, dieterand Brionfor their help and posts, and all the ones

who developed USBDM!

Happy USBDMing

Hi Erich,

I using Universal Multilink rev.A with MKL15128VLH4. I have

connected in a dummy board SWD_DIO, SWD_CLK, TVCC, RESET

and GND on PORT G. I try to program microcontroller by CW 10.3

or CW 10.4 but I fail and the software tell me that this isnt possible

to connect to the programmer do you know any issue on this

microcontroller with U-Multilink? Can you help me? I choose this

microcontroller for two project and now Im desperate!

Thanks

Marco

Erich Styger


Hi Marco,

no I have not seen any issues on my side with using the P&E

Multilink to program Kinetis devices, at least not such kind of

issues. Does it work with a non-custom board? Like the

FRDM board (solder the SWD header on it). That way you

know your setup is working. Then check your wiring to the

KL15. Best if you do it like e.g. on the FRDM board to make

sure you have the traces right, with the proper resistors/etc.

For our boards we replicated 11 the schematics as on the

FRDM boards, and this worked very well.

I hope this helps.

Thanks for the replay!

I have the same issue with FRDM-KL25 at this

point I think that U-Multilink is broken! what do you

think?

Thanks

Marco

Erich Styger


Have you configured it to use SWD (use SWD re-

duced pin protocol for communication)? Note that if

you use the JTAG protocol, this will not work, you

need SWD enabled. See bitmap USB Multilinke in-

stead of OpenSDA in CodeWarrior

Yes I have setted this check in the configuration box!

Erich Styger


Maybe check the SWD cable (orientation, broken wires). It

happend to me that I had a bad cable. Otherwise: get in

touch with P&E support?

warcomeb


Yes, I tested this solutions I contacted the technical

support of P&E, without results, their solutions have

not worked.

Erich Styger

on September 2, 2013 at 18:10said:

Hi Marko,

In general, the answer is no. But it all depends on what you

are using: the instruction set and the main core is the same.

But the peripherals and memory map very likely is different.

Then it will not work. But I think for very simply things you

could do this. But no guarantee.

I would like to program now a TWRK70 with the freedomboard

Thanks again !

Erich Styger

on December 17, 2013 at 19:56said:

Hi Jems,

the KL25Z has a SWD debug interface, while the K70 has

JTAG. So you cannot use the KL25Z (OpenSDA SWD) for

this. And to my knowledge USBDM is only supported by

CodeWarrior.

Hello Erich,

I want use this USBDM with Freedom Board to debug another

board.

I am using KL25Z128 controller.

I have my old code without USBDM in it.

So in debug configuration setting i added new connection for

USBDM and i added USBDM target.

Now i can Run or debug the code only for the first time.

But after reconnecting the board i am not able to burn the code.

Error occurred as : -Failed to resume target process.

I have created new project with USBDM addition.

It is working. But I want the USBDM in my previous project.

Is it possible to add new connection through debug configuration

setting?

Please suggest if I am missing something.

Or I need to create new project?

Hello Durgesh,

can you verify that it works with another FRDM-KL25Z

board? I suggest to check your wiring. Failed to resume tar-

get processor means that it is not able to reset and halt the

processor, so have a look at the reset line.

I hope this helps.

Hello Erich,

Thanks for replying.

Before cutting the J2, I have downloaded the test

code onto freedom board through SWD debug

header. It worked fine. That means my SWD connec-

tions are correct.

Again I could able to program my tar-

get(MKL25Z32M4) using Multilink through SWD. So

my target board SWD connections are also correct.

But i am unable to program my target(MKL25Z32M4)

Another thing I want to mention is I have programmed

my target controller using ARM Programmer(Flash

board. Its working.

I am unable to guess what could be the problem of

same USBDM while working with codewarrior to pro-

gram different microcontroller(other than the freedom

board)?

I want to program my target with codewarrior using

USBDM as it provides me debugging facility.

Guide me if there is any other debugging work I need

to do

Is there any way to log my information to you, If i

dont find any solution.

Thanks in advance
