If you try to program an Arduino with "Arduino as ISP" programmer you obtain the following error under Linux ARM version of the IDE:

**avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x15
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x15

avrdude: stk500_getparm(): (a) protocol error, expect=0x14, resp=0x14

avrdude: stk500_getparm(): (a) protocol error, expect=0x14, resp=0x01
avrdude: stk500_initialize(): (a) protocol error, expect=0x14, resp=0x10
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.

avrdude: stk500_disable(): unknown response=0x12
La porta seriale selezionata avrdude: stk500_disable(): unknown response=0x12
non esiste o la scheda non è connessa**

If you try to do the same thing (with the same source code) under Linux (x86) or Windows O.S. it works great. It's only an ARM version bug.
