qconn Performance Over the Internet   
I would like to use qconn to deploy and debug my programs over the Internet to my embedded system, but the performance 
right now is intolerably slow. It takes about 30 seconds from pressing the Debug button until the debugger breaks at 
main, and stepping through the program is just as slow.

I am pretty sure I have had much better performance debugging with gdb and gdbserver cross tools before. Has anybody 
else had this issue with qconn? How might I fix it?

RE: qconn Performance Over the Internet   
Qconn is definitely not designed for speed.

Re: qconn Performance Over the Internet   
That typically means you have a mismatched libc.so symbolls on host vs 
target

Re: qconn Performance Over the Internet   
I see. I did not think that the target needed debug symbols. Pardon my asking, but how could I verify that the target 
symbols match the host symbols?

Also, I think I should note that the target device does not have writable storage. I will be updating the image with the
 dev-eidi driver soon, but right now I believe it is using RAM. Could that possibly be the problem?

You don't need debug symbols on the target, but the version of libc.so 
on the target and that in the Momentics SDK needs to match.
