strange problem to debug stm32f20x board based via ULINKpro emulator?

DavideG

hi all.

i normally connect to a stm32f20x based board via ULINK2, and it works fine.

i tried with ULINKpro emulator and the it does't work at all. This message is displayed: No ULINK2/ME Device Found.

even if the debug "Use"configuratione has been changed correctly (i think :)) in ULINK Pro Cortex Debugger.

On the other hand, i normally use the ULINKpro emulator (just the same emulator) with board based on stm32h743xx micro, and it works fine.

It seems that in the first case, mdk looks for ULINK2/ME the same also when you declare and use ULINKpro. 

what's the matter? anybody could help?

thanks a lot.

    Hello,

    I've not experienced this before.

    To check, have you selected to use ulink Pro (it is not selected in the screenshot above):

    When you click the Settings button, is the UlinkPro identified?

    Hope some of this helps,

    Ronan

    PS - I will move your thread to the Keil specific forum.

    hello. 

    sorry for the wrong screen shot: i tried in several ways.

    i ve just now repeated the test and i have the same disappointing message.

     thisi is the settings:

    and this is the result when trying to enter debug session :

    to add information:

    when i push the ok button in the message above, this other  message is displayed:

    and the build output window tells me:

    thank you the same for the attention.

    This is very strange... we can see from the Settings view that the adapter is (correctly) identified as a ulinkPro. However the error says that the tool is looking for ulink2.

    I've never seen this occur before... but I suspect something is corrupted in the project file... if you create a new project, does the issue continue?

    If your project is complex, you should be able to export (Project > Export > Save Project to CPRJ Format), and then re-import (Project > Import > Import project from CPRJ format), to retain the build structure, and can then configure debug settings again.

    Hope this helps?

    hi.

    thanks for quick answer.

    i tried your suggestion but it is not possible:

    "Export to CPRJ project file" is grayed and not operative.

    i'm investigating a little cause the project is complex enough (that is : it makes part of a multiproject and it  is quite a little old fashioned. 

    the only active option in Export menu is "Save Project to uVison3 format". do you think i can try this kind of exporting?

    dear Ronan. 

    sorry for boring you again: you were right: something corrupted somewhere in the project files.i tried to rebuild "manually" the project and i yet never seen again the no consistent message about ulink emulator missing status.

    i also try to change the emulator to ulinkm2 and to ulinkpro again and uvison run fine in every case.

    sorry again.  sometimes the simplest things matter a lot.

    thanks
