Antwort: Re: Re: Remote Debugging Of Multithreaded Application on PPC 82xx

[Frank dot Christ at RSBICK dot rohde-schwarz dot com]

Hi Daniel,

I am using glibc 2.1.3! Here is my remote log!
The following two lines seem suspicious to me!
     Packet Z0 (software-breakpoint) is NOT supported
     binary downloading NOT suppported by target

Any hints regarding the remote log?

Thanks,
Frank
