Unable to program KL25Z with PE Multilink

jaluna — Mon, 11 Mar 2013 07:42:33 GMT

Dear friends,

we need help with our first KL25Z128 custom board, we are unable to program using the "PE Multilink Universal". For the CPU, we have based our design in the FRDM-KL25Z (see attached sch, please). We can program the FRDM-KL25Z using the Multilink (J6 header) but not our board. Any help will be appreciated.

As difference, note:

- we don't have mounted external clock

- reset pin, 0.1 uF instead (also tested with1 uF)

The progammer have the following lines connected, as the FRDM-KL25Z:

- VCC

- GND

- SWD_DIO_TGTMCU

- RST_TGTMCU

- SWD_CLK_TGTMCU

Thank you,

Juan A Luna

Hello,

What is the error you have? Have you tried a mass erase with CW flash programmer?

Regards,

Luis

Dear Luis,

the problem is (not textual) "unable to connect to target". I don't have tried a "CW flash programmer", where can we find it?

We use CW 10.3

Hello,

You can also enable log in the connection to know more about what is happening.

The error is

Description:

Error launching Project_FLASH_PnE U-MultiLink, ARM GDI Protocol Adapter : Can't connect. The Debugger can not connect to the P&E device

Hi,

That problem is not related with your custom board. You can not connect with debugger, not with target.

Ok, Try the following. Use any project working in the FRDM board and verify that you can debug in FRDM. Then, switch to your custom hardware and connect debugger and power the custom hardware.

Force mass erase on connection:

Yes, I think you are right. I cannot connect to FRDM board...

Added: Using the "Open SDA" in FRDM the error is the same. It seems a CW 10.3 problem.

Hi Juan,

Did you install P&E driver? You can found it here (hyperlink.).

Edit: sorry I have seen now that it works with freedom.

Hi Antonio,

thanks for your message, yes I have installed it. But I think the problem is the Multilink itself. I have ordered a new one for test again.

Dear all,

We have received a new PE Multilink Universal. Now we can program the FRDM-KL25Z but only if the jumper J11 is joined!!! We have verified that we cannot program FRDM-KL25Z if we remove the jumper (the track has been cutted in bottom). So the question is how to translate this programing scenario to our custom board (that of course, don't have opensda) ?

Ok, I have checked the sch, is normal!

But we still unable to program our custom board.

Any help will be appreciated. Must be a hadware issue.

Regards,

Juan A

Since you seem to have used the 6-pin connector (port c) instead of the 10 pin (port g) (the one Kenitis) , perhaps that is why you can not connect to your board?

Hi Juan,

J11 is explained in the FRDM board User Manual:

http://cache.freescale.com/files/32bit/doc/user_guide/FRDMKL25ZUM.zip?fpsp=1

5.2.1 Debug Interface

For your custom hardware, you only have to ignore the openSDA circuit. Implement the figure 5 of the FRDM UM, connecting PIN 4 to SWD_CLK, PIN 2 to SWD_DIO and pin 10 to RESET.

Best Regards,

Luis

I'm using Port G.

Thank you.

Yes, we have based on it. Please, check sch on first post.

Thank you

Hi again,

Yes, As Jim said, if you are using 6 pin connector, just change the same lines to the right pins.

Luis

JimDon — Thu, 14 Mar 2013 18:16:42 GMT

Your first post shows a 6-pin connector instead of the 10 pin one, so it is not possible for anyone but you to know it is correct.

You, of course did not connect pin 10 to RESET since a 6 pin connector does not have this pin.

jaluna — Thu, 14 Mar 2013 18:22:43 GMT

I'm using a custom connector, the same that have worked fine with the FRDM board.

5 lines: TVCC, GND, /RESET, TMS and TCK (names in Port G)

Thank you

More info:

When I plug the Multilink to my board (that have only the mcu and power) the voltage to Reset pin goes low permanently.
