So, here we go.
I've compiled...
- a stock gdb with Ubuntu (11.04) patches (apt-get source gdb) and the
one patch for remote.c you pointed me to.
- flickernoise (using the compile-flickernoise script as explained in
scripts/README)
I've then flashed my MMone with msd-may2011 except that I've replaced
flickernoise.fbi with the one I've compiled.
All the following is run from
~/Development/milkymist/milkymist/flickernoise.git/src/bin
Note, for the first run I've not booted the MMone, I've merely
connected power (eth, usb keyb, usb mouse, vga, line-in was already
connected) and then started gdb and waited a short while.
==========================================
$ cat gdb.script
set debug remote 1
set remote interrupt-on-connect on
set remote interrupt-sequence BREAK
target remote /dev/ttyUSB0
$ ~/Development/root/milkymist/bin/gdb -x gdb.script flickernoise

==========================================
In the following run I've actually booted the MMone right after
connecting with gdb.
When I was closing the 'no patches found' message in flickernoise, gdb
stopped with the "malformed response" error.

==========================================
Any idea why it's doing this?
So far I was not able too get it to a point where I could run a
backtrace.
I'll now let the 'airs' patch run till it hopefully gets stuck and see
if I can do any kind of post-mortem from there (not sure that'll work).
Please let me know if I'm doing something wrong here.
