Hi,
I cross-debug the activities of a Unix-VM running on a PowerPC/Linux embedded system.
1. Via gdbserver/gdb I am able to see that main() is executed up to the point where the interpreter is called 2. I can also set a breakpoint at the switch(currentBytecode) of the interpreter and break there once 3. After continuing I do not come back to this breakpoint a second time 4. I can interrupt execution with Ctrl-C (SIGINT) and tell gdb: call printAllStacks(). This yields what is shown at the end of the mail 5. I use Cuis1.0-0204 which fits nicely in my 16MB flash memory. I modified it so that an early alife-message is sent to stderr. This is done when executing the class method startUp of the Delay class. This works well on my intel/Linux desktop system. But I do not get there on my PowerPC/Linux embedded system. 6. I use Bert Freudenbergs changesets to print SqueakDebug.log on stderr. They work well on intel/Linux but on the embedded system I apparently do not get a MNU.
What possibilities do I have to get further diagnosis?
A last question: There is a document "porting1.pdf" written by Ian Piumarta which might be helpful. Does anybody know where I can download a readable copy?
Kind regards Pascal
