connector.
3. Verify the logic power source. Measure +5VDC between the GND and +5V connections
on the TB1 power connector. If the +VIN supply is present and the +5V output is not pres-
ent, immediately disconnect power from the board. Contact support@axman.com by
email for instructions; provide board name and problem.
4. Make sure that the RESET line is not being held low. Measure the voltage level at the
RESET* signal on the BUS_PORT connector.
5. Verify the communications port is working by substituting a known good serial device or by
doing a loop back diagnostic.
6. Ensure NO_AUTO jumper is installed. This will prevent any loaded program from execut-
ing at power-on or RESET.
7. Disconnect all external connections to the board except serial cable and the wall plug.
8. Verify the presence of a 16MHz clock signal at the EXTAL input pin.
9. Contact support@axman.com by email for further assistance. Provide board name and
describe problem.
Tips and Suggestions

Make sure all jumpers are set correctly if trying to program memory or start the utilities.
Make sure the serial cable is bi-directional and connected securely to both the PC and
the board.
Make sure the serial cable is connected to the correct serial port.
Make sure the power is supplied to the board. Only use a 9 volt, 200mA minimum wall
adapter, or DC power supply set to provide 9V output to the board. If applicable, make
sure the power strip is turned on.
Make sure you load your code to an address space that actually exists. See the Mem-
ory Map if you’re not sure. MCU mode (single chip or expanded) changes the memory
map.
If debugging under embedded monitor, make sure you're not over-writing reserved in-
ternal SRAM.
If running in a multi-tasking environment (such as Windows) close all programs in the
background to reduce the potential for conflicts.
