Problems with run tests on a i386 platform

Problems with run tests on a i386 platform

[Hansjörg Petriffer]

I have the following problems with using gdb wiht a i386target (with ecos
running).


I'm not sure if I make something wrong.

I receive the following messages:

It seems for me that something goes wrong with the serial comunication,
because it makes no difference if the remote is running.  
As serial cable I use a Simple null modem without handshaking. Is this
correct?

Thanks for any hint!

What happens when you do these steps manually, but set remotedebug to 
"1"? That might give us a clue about the malformed packets below...

Okay, scratch that. You're timing out. There is something wrong with your 
serial connection. Try using (or not using) a null modem adapter, 
different serial ports. Try setting the baudrate to 9600, etc.
