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)

Got message seqno 51 (command_sequence == 51)
