Communication
timeout
0xFF71
1.
The drive's debugging cable
is
disconnected
or
not
reliably connected
2.

make
sure
that
the
connection is reliable
2.
Replace the debugging cable
with one with isolated serial
port
3.

the
anti-interference measures
of the debugging cable, for
example, by adding magnetic
ring,
conducting
reliable
grounding of the debugging
computer, powering on the
debugging
computer
separately from the drive
