MK20DX256VLH7 locked/problems mass erasing

Hi everybody, I am developing my own k20 board specifically with mk20dx256vlh7, my problem is that I have already mass erased 2 chips ( first to do before debug and program), but I must have erase (and program) 4 more, I am doing same process as 2 I have already erased but without good results with 4 chips.

 

By reading posts and documentation I know that maybe it's a registers issue, but cartainly this is a new issue for me.

I am using PE micro multilink universal, SWD/JTAG configurations, IDE Code Warrior.

 

I have:

Reset_b: 10K pull up

Ez_port: 10K pull up

DIO: 10K pull up

CLK: 10K pull down + capacitor 1000pF pull down

 

I followed above circuit recommendations from other posts and datasheets from freescale.

 

I attach some print screens of my process:

103706_103706.pngpastedImage_3.png

103707_103707.pngpastedImage_4.png

103708_103708.pngpastedImage_5.png

 

 

I am really  concerned about this, cause I can't explain how it's possible that I have succes with 2 chips (both configurations SWD and JTAG) but no with  other.

 

I hope you can help me with this.

 

Thanks so much.

Hi Mario,

May be it's another problem.

I think you're using CW for MCU v10.6.

We released several patches (updates) for this version which are:

    - Update 1.0

    - Update 2.0

    - Update 3.0

We've a problem with the Update 3.0 and Muliltink interface.

In May the MCU V10.6.4 was released.

This is not a patch but a new release and must be installed in new folder.

Please can you have a look to the link:

Problem with Multilink Rev C - not running after MCU V10.6 Update3 installed & CW for MCF V7.2

Have a great day,

Hi Pascal, Thanks for your response.

I am using CW for MCU v10.6.4, Multilink universal Rev C, and it works perfect to mass erase and program 2 of my k20 chips. The problem is when I try to do the same with other 4, It appears that "The Debugger can not connect to the P&E Device"

I already have installed the P&E micro update and stills working with my 2 erased chips, but no with other.

Thanks for the supporting!

Mario,

Using the same tools and hardware configuration you can flash the project on 2 devices without problem but not on other devices.

It seems you tried the Flash File to Target and launching a debug session.

In both case you can not load the application on board.

As it's working with other device the Multilink Universal interface is working fine (driver installed correctly).

Is there a difference between the working and not working device ?

Do you use the same board and just change the chip ?

Or is it 2 boards (I mean 1 for each chip) ?

    - same devices are used for boards ?

    - same mk20dx256vlh7 chip ? Check the mask

Can you try with a generic example created with the wizard (File + NEW) ?

Can you load the sample code on board ?

Can you try to keep the Multilink plugged on your PC but not connected on the board ?

is it same error message ?

Have a great day,
Pascal

Pascal,

I have differents boards for each chip(6 in total), first one is a pcb hand made by myself, all others were donde by machine (exactly the same), but unfortunately just 1 works, so I can deduce circuit is ok.

pastedImage_4.png

I have tried creating a New+File+ new bareboard project (no code just in blank), but stills failing.

executing flash file to target I obtain the following

Error executing task K20DX256M7.

Error:  Connect Failed.

Can't connect. The Debugger can not connect to the P&E device(ARM GDI Protocol Adapter)

Error: Connect Failed.

Trying to load program to the board I obtain:

Error launching prueba_2_FLASH_PnE U-MultiLink

ARM GDI Protocol Adapter : Can't connect. The Debugger can not connect to the P&E device

Keeping Multilink plugged to PC and disconnecting board I get same errors showed above.

What else can I do?

Thank you very much for your supporting.

Hi Mario,

Difficult to say what is the problem.

The first, and most easy answer will be there is a problem with boards.

If same PC, application, interface is working on some board and not on other boards, it will have sens to say the problem is on boards side.

The Flash Programmer and the Debugger are not using the same "flash application".

I don't think there is a problem linked to the Flash features else I would expect 1 working solution.

As the problem appears on both features I think you should search the cause of the problem in another direction.

In both case the same interface configuration is used.

Please can you enable to log generation for P&E interface ?

pastedImage_0.png

Now can you try to launch debug session when the working board is plugged and when not working board is plugged.

On my side with the TWR-K20D72M board I see:

Hi Pascal,

Yes, I know this is difficult and really weird, I can't find explanation about this.

I have tried what you comment, enabling logging, but I get same error, The debugger cannto connect to the P&E device, The problem doesn't allow even to connect with target. As you, I'm beginning to think that there is a problem with the board.

Do you have any recommendation to add, replace or remove to my circuit?

I have:

All VDD-3.3 V

All GND-GND

Reset_b: 10K pull up

Ez_port: 10K pull up

DIO: 10K pull up

CLK: 10K pull down + capacitor 1000pF pull down

I'm not using crystal.

Thanks for your support.

Hi Mario,

I'm not Hardware expert so I can not give you recommendation for your board.

Now this morning I've just performed another test with my demo board.

As explained in my previous post I can flash the code on board without problem.

Now I tried to flash (launch debug) it when the board power is down.

I got similar dialog saying:

Hi Pascal,

I have tried to launch a test program to one of my working boards (firts attempt with the board plugged and second one unplugged), and I get same as you on multilink console dialog, obvoiusly when I disconnected the board, I couldn't launch it any program.

Now, trying with one of the non-working boards,

When I try to mass erase, I get following in the multilink console dialog:

I have checked power supply in my non-working boards, everything is correct, I have 3.3 V, and the yellow led on the multilink tool lights.

Thank you Pascal.

If I'm right the problem is reproduced with sample example too.

You're using CW for MCU V10.6.4 which is the last version.

There is a dedicated tool for Kinetis devices: KDS V3.0.0

Can I ask you to install this tool (Free of charge) and create an example ?

The Mulitlink interfaces are supported too.

It could be interesting to know if you reproduce the problem with this tool too.

I've found another post which "could be" similar to your problem.

Hi Pascal,

I have installed KDS 3.0.0

I created a new kinetis project.

I tried to flash one of my non working boards, I get the following:

Also, I can launch example program I have created.

I have a question, If devices are secured? All of them are secured at the beginning?

If no, I think I have good luck with 2 of my chips but no the same with others 4.

I re-checked (again) my connections, and everything is ok, the circuit is in the same conditions that my working boards.

Sorry for too long text,

Thank you Pascal.

Mario,

I contacted P&E regarding the difference with the flash version we used.

Don't think if this will help but:

+++++++++++++++++++++++++

Have them update to the latest firmware via our firmware update tool and let me know how it goes.

They may also want to try reducing the BDM shift frequency as this might be an communication issue since the older Multilinks are a lot slower.

+++++++++++++++++++++++++


Have a great day,
Pascal

Pascal, Vicente:

Aftrer update the firmware I tried flash file to target , problem stills appear with non-working boards, even I try with a new board, new chip (same circuit), but no good results. Also I change the BDM shift frequency, I use (9) and (26).

pastedImage_0.png

Working boards go ahead without problems after updating and even change BDM shift frequency.

I think after doing all these tests, as Vicente comments, I will swap a functional chip to one non-working board and try to flash and launch program.

I was reading that first you have to do before launch a program is to mass erase the MCU.

mass erase means to unsecure the MCU?

It's possible that 2 of my chips came already unsecured from factory?

I will do the swap and let you know what happens.

Thank you for your support.

Mario.

Hi Pascal,

Ok, I will update the firmaware and check it.

Btw I have same details as you

C:\Freescale\CW MCU v10.6.4\MCU\bin\plugins\support\ARM\gdi

pastedImage_0.png

I'll inform you in a while how it goes with the updated firmware.

Thank you.

Hi Mario

I believe that the problem is hardware, if you have two board working, would be possible that you perform a swap with one of the failed board?

with this we can focus if this is a hardware problem on your board or if there is something with the Multilink connection.

Maybe you have some open pin on the board...

Hi Vicente,

I have changed a chip from one of my nonworking boards to one of my working board, I couldn't mass erase or debug it,

This week, I am doing a new board, I will put a new k20 chip, and I will try to debug it.

Do you think there is a problem with the MCU?

Thanks.

Hi Mario

You put the failed MCU on a "golden board", this is correct?

Please check that you have all pins properly solder, and check that all the voltages are correct, check if you have any signal on the reset pin?

if the device has not any program on it you should be that the reset pin is oscillating.

Also check if you do not have any low impedance on the device, this in order to check if really the MCU is damage.

Please let me know the results

Regards

Hi Vicente,

Yes you are right, I am using a board that works prevoiusly with a chip removed from other board that didn't work.

I have re-checked and cleaning my board,  MCU is ok, VDD's GND's, JTAG/SWD Pins.

I cannot connect to the device.

On the reset pin I have 0V all the time, even when I try to mass erase or debug the MCU.

I have:

Reset_b: 10K pull up

Ez_port: 10K pull up

DIO: 10K pull up

CLK: 10K pull down

What else can I try?

Thank you.

Hi Mario

Can you please test with out the pull up on Ez_port: 10K pull up and without the pulldown on CLK: 10K pull down

Please let me know the result

Hi Vicente, I'm sorry for the late response, I was not in the office to do more testing.

I removed the pull up on Ez_port and pulldown on CLK, I still can't connect to the target.

I swapped the microcontroller (to check if my boards were the problem) from a non-working board to a working board, but without success.

Finally I made two new boards, one of them works perfectly but the other didn't, I am using same circuit for both.

I think there is a random problem with the chips, some of them are secured and I can't mass erase them or debug them.

Since we're in a hurry and need to finish the project as soon as possible we changed the microcontrollers but if you can find something about this problem I would like you to let me know, because in the near future I'd like to use this microcontroller for other projects.

Regards.

With KDS v3.0.0 and With MCU V10.6.4, you've the same problem.

The same 2 boards are working on both dev tools but 4 same boards are not working on both dev tools.

Is there a problem with the chip on 4 boards not working ?

Back on MCU v10.6.4.

Extract of the info you sent:

    INF: P&E Interface detected - Flash Version 9.33

On my side I see:

    INF: P&E Interface detected - Flash Version 6.15

    INF: Device is K20DX256M7.

The \CW MCU v10.6.4\MCU\bin\plugins\support\ARM\gdi\arm_pne_gdi.dll is used.

I will contact P&E to have more info but I don't think the problem is linked to that.

I will contact Hardware colleagues too to get their comments about it.

Keep you informed.

Have a great day,
Pascal
