#18 Slow connection Using Dragon Jtag

[Zajc3w]

Im runnin latestst avarice.
latest avrDragon frimware/hardware
Atmega 128 @ 8MHz
Jtag clock set to 1MHz
everything goes smooth untill first "step" command in GDB
it takes 10-15 seconds for single step over line: PORTA = 0xFF;
below part of avarive output
my guess is AVARICE is sending incorrect message ack response(but i'm just a noob ;P)

Just compiled from SVN - now i can't debug at all, both step and continue commands give more or less same result.
