on-target debug problems

[enrico_groups@libero.it]

Dear All,

I am trying to debug an application on a Symbian OS UIQ phone (ARM thumb).

I tested the connection and setup with an example application and everything works fine. I use gdb on windows command prompt and I have a gdbstub provided by the manufacturer.

When I try to launch my application using "run" on gdb on the pc, on the target device (on gdbstub) I get the following error message:

  Failed to load app DLL
  (epoc error is -1)

What does this mean? What could be the reason?
Is there any way I can find out which DLL is missing?

I could not find anything related on-line, so any pointers are welcome.


Thanks,
Enrico
