Mote Application Note: ATmega 128 Programming Problems and Fuse Control
UISP Parallel Port Problems
Some users experience problems with the UISP firmware download program. These
problems manifest themselves in several modes:
1. UISP cannot detect the presence of the ATmega128 processor on the Mote
processor board (MPR).
2. Once programmed the part cannot be reprogrammed.
3. Flash errors occur after download, during the verify cycle.
Assuming that the MIB programming board is correctly connected to the PC and the
mote power supply/battery voltage is adequate, one of the following is generally the
cause of these problems:
1. The PC printer port driver is not supported correctly by the UISP program.
2. The PC is outputting serial programming data to the mote too fast.
If either of these issues occurs, the ATmega’s fuses may become set incorrectly during
the programming process. Depending on which fuses get incorrectly set, this can be fatal
and require replacement of the COU chip. Normally, the fuses can be reset to the correct
state using the UISP program with fuse control or a JTAG ice.
The following items should be checked if problems occur:
1. Use the simplest printer port driver in the BIOS. These drivers go by various
name (SPP, AT..). The printer driver EPP and ECP can cause these problems. To
change the driver, reboot the computer, enter the bios (before Windows boots)
then change the printer driver.
2. In the makerules file (tinyos/apps directory) slow down the uisp clock. Replace
the following:
PROGRAMMER_FLAGS=-dprog=dapa $(PROGRAMMER_EXTRA_FLAGS)
With:
PROGRAMMER_FLAGS=-dprog=dapa –dt_sck=40 $(PROGRAMMER_EXTRA_FLAGS)
This will slow down the uisp serial clock to 80usec (40 hi, 40lo)
Faster times may also work.
3. If using batteries, check the battery voltage. If the battery voltage is less than 3.0V
the flash may not be reprogrammed correctly. This can also cause the
ATmega128 fuses to be set incorrectly which will defeat any further
reprogramming. Users are advised to use a Crossbow MIB500 interface board that
detects low battery voltages. This unit also accepts an external wall mounted
power supply. (5-15VDC)

Mote Application Note: ATmega 128 Programming Problems and Fuse Control
The setup is identical as used for general UISP programming of a MICA Mote (eg make
install.15 mica)
Configuration
You must use a version of UISP.exe that is v2002.06.26 or later.
To determine the uisp.exe version:
At cygwin prompt:
uisp –h
The following should be returned:
uisp version 20020626

To Program Fuses via UISP
1. Run CYGWIN
2. Install MICA PROGRAMMING module (w/ Mica mote installed) on LPT1:
port of PC. Power up board – power is NOT available from LPT1 port.
At Cygwin prompt (assumed to be ‘$’):
$ uisp -dprog=dapa --rd_fuses//note the two (2) dashes - - in front of ‘rd_fuses’

This indicates everything is working ok.
To disable JTAG and ONCHIP DEBUGGING (doing so is necessary for correct
operation of the PZ Sensor module):
$uisp –dprog=dapa --wr_fuse_h=0xD9
To enable JTAG (doing so is required for JTAG download and debugging):
$uisp –dprog=dapa --wr_fuse_h=0x19
It is recommended the fuse state be verified by reading the settings following a write:
$uisp –dprog=dapa --d_fuses
