The Debugger can not connect to the P&E device.

[adrien_segura12]

Hi !

I'm new on Codewarrior and i use a Universal Multilink (Farnell 2315740) to load my projects.

after a trip to make my project work on an other computer with the multilink, i tried to load my 

project on my work computer. And then codewarrior send me this error :

Launching has encountered a problem.

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

I saw that i got the same problem if i diconnect the multilink. but, it seems to work, both leds (orange and blue) 

are on, and i re-installed my drivers and codewarrior .

I noticed that this error occured not only on codewarrior.

Anyone has an idea of how to solve this problem?

Thanks for reading me !

Hi Adrien Segura ,

Please send us more information about your query:

1. Do you use demo board or customized board? part number?

2. Your CW version?

Have a nice day,

Hi,

thanks for your reply ! I use CodeWarrior V 10.6.4,

my card is customized and used for a bus communication application.

I re-tried to use the multilink on other computer and other applications, it seems that i always have the same error message :

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

Any ideas? thanks for your answers !
