P&E Coldfire multilink and CW 10.5

[gaetanoanania]

Hi all,

I am using the coldfire MCF54415 , CW 10.5 and the debugger P&E Coldfire multilink (its version is really old) .

So far ,I haven't been able to programm my coldfire . An error occurs during the flashing of the firmware. The debugger is able to erase the memory but when it tries to write early the process is stopped .

The error is " Loss communication ......"

Do you have any advices that could help me? And in addition what are the different between P&E Coldfire multilink and P&E Multilink?

When I made a new coldfire project I didn't find the P&E Coldfire multilink but just P&E Multilink. Is it the same?

Thanks in advance.

Greetings,

In Codewarrior we mention just P&E USB Multilink, but that indicates all multilinks that can support ColdFire. This means you can use the USB ColdFire Multilink, the USB Multilink Universal, and the USB Multilink Universal FX. They should all be able to talk to your chip. For you, that means no need to purchase any new hardware.

The most popular reason for communication loss is that you did not lower the debug shift frequency within the debug configurations. Try lowering this frequency to establish a better connection to your chip. In my experience, lowering the shift down to option 15 is the sweet spot for ColdFire chips.

Hi Takao,

I took your advice but I am carrying on to have the problem. There is a  strange behaviour:

if I try to install the firmware more then one time I will have the same error  I see the follow log:

"

"

In additon a pop-up form Problem Occured tells me:

"

Error:  Program failed.  Couldn't initialize registers<s>thread exit: Stopped, 0x0, 0x0, cpu68K, Unknown (state, tid, pid, cpu, target)</s>

"

Thank you a lot ...in advance.

Gaetano.

Greetings,

I want you to create a new project in Codewarrior for your chip and see if you are able to debug the basic default project. If you are, then there is something in your project's settings or possibly something in your code causing problems. If you are not able to debug the default project, then there is something wrong with hardware or your project setup.

Have you gotten your setup to work in the past or is this your first attempt?

Hi,

I solved the issue plugging a decoupler between the usb port of PC and the USB Coldfire  Multilink. The "Loss communication" was due to the noise on the communication channel.

Thank you.

See you next problem.

Hi Gaetano,

Do you refer to this interface ?

Hi Pascal,

yes I am using that debugger.

Thank you
