Running avr-gdb in combination with pysimavr

[SebastianZug]

Hi ponty,

best wishes for 2019 :-)

I used my hollidays for some experiments with AVR and intend control pysimavr via avr-gdb. For this purpose I extracted the following python code from the Button.py-example to initialize the simulation:

#!/usr/bin/python
from pysimavr.avr import Avr
from pysimavr.swig.simavr import avr_gdb_init, cpu_Stopped

mcu = "atmega328p"
freq = 8000000    

avr=Avr(mcu=mcu,f_cpu=freq)
avr.gdb_port = 1234;
avr_gdb_init(avr.backend)
avr.state = cpu_Stopped

try:
    while True:
        time.sleep(0.01)
        print("PC %s" % hex(avr.pc))
        print("Avr state: {}".format(avr.states[avr.state]));

finally: avr.terminate()
print "Aus Maus"

I compiled an older version of gdb (7.0.1) for avr target and run it with the following command but I did not realized a connection between simavr and avr-gdb. Any idea?

./avr-gdb
