error 56: cant open file - although project did work properly

Hello,

I didn't find anything helpful in the knowledgebase or through google, therefore I'll post my problem here.
I have a project that did exactly what it is intended to do, one week ago (including failure free Debugging on µC). Now I get the error 56 mentioned above when I try to debug it on the µC but I did NOT change anything, neither code nor configuration! Is this a bug? Did anybody experience the same problem before? And why isn't there an entry in the knowledgebase, although there is a list with all errors and warnings implemented by Keil?

The µC is a C164CI and the code is a bit too long to post it here, but of course I will do it, if it's necessary to solve the problem. I also don't know what further information you will need cause I don't have any idea what the problem might be. So feel free to ask whatever you want :)

Thanks in advance for any helpful advice.

Greets, Jan

  • Hello,

    I found a poor little workaround for this problem, but it isn't satisfying at all:
    If I delete all files in den project folder except for the source-files, the *.uv3, the linker file and startup code (START164.A66) and then build the project (after setting the monitor configuration from ROM-166 to the specific module) the on-chip-debugging works for exactly one time...

    Maybe this could be a clue for somebody to find out what the problem might be?
