Perhaps the mica2dot is using the UART (if it has this ability like the
mica2). Check the switch on the MIB510 is in the on position. This stops
the mote from accessing the serial port.
Also, if you have a JTAGICE you could try to access the MCU fuses using
AVR Studio.

The voltage levels are fine on the mote and programmer board. I have been using this serial cable
for some time now with no problems. I had used the same command to try to read the fuses with no
success (I also retried just then), i get the "programmer is not responding" error (with
about every 3rd attempt giving "device is not responding correctly"). If the problem is
not the fuses do you have any idea what else could be causing these errors?

Subject: Re: [Tinyos-help] Fuse Help
I had similar problems with my own node, but that's because we
designed
it from scratch and the MCU fuses were set as they are from the
factory.
I think (I don't know this for certain) that the mica2 and mica2dot
fuses might be preconfigured for that board, so you shouldn't have
any
problems and it seems that most people don't. The "programmer not
responding" error is not the problem of the MCU, but the programmer
board. Perhaps check the voltage of it and that you have the
correct
serial cable. In my installation of cygwin I found that it would
fail if
I specified the serial port as 'com1'. Instead I have to use
/dev/ttyS0
and it works fine.
To read fuses:
uisp -dprog=mib510 -dserial=/dev/ttyS0 -dpart=ATmega128 --rd_fuses

Hi,
I am having trouble programming a mica2dot mote using an mib510
programming board. I get errors which alternate
between "programmer is not responding" and "device is not
responding correctly" when I try to load code onto the mote.
>From reading the help lists I beleive this is a fuse problem,
however, when I try to use a uisp command to read the fuse
values I get an error saying the "device is not responding
correctly". Has anyone encountered this before? And if so, what
can be done to fix this problem?
Thanks,
Sam
