I can also see that gdb sends a =E2=80=9CM1e40,2:f0b5=E2=80=9D packet in ei= ther case. The address is unchanged so it must be masking off that Thumb bit. If it's in A= rm mode it sends a completely different packet: =E2=80=9CM1e40,4:f0b503af=E2= =80=9D. --=20 You are receiving this mail because: You are on the CC list for the bug.=
