Troubleshooting

5.1.2 Communication Can’t Be Established with the Board
1.
Make sure the Starter Kit is connected to the PC and powered on.
2.
Make sure that the
“BKGD ENA”
and
“RESET ENA”
jumpers in the
“USB TO BDM”
section are inserted.
3.
Make sure that the
“MODA=1”
and
“MODB=1”
jumpers are removed.
4.
When connecting to the Starter Kit via the built-in USB connector, no
external tool must be connected to the BDM connector.
5.
Use only the provided USB cable, or a cable that is USB 2.0 compliant.
6.
Make sure you are working with the correct hardware model. To
view/change the hardware model in use, choose
“inDART-HCS12 >
MCU Configuration”
from the CodeWarrior debugger’s main menu.
7. If
the
“inDART-HCS12”
menu is not present in the CodeWarrior
debugger’s main menu, this is because the target has not been
recognized by CodeWarrior (“No link to Target” appears in the status
bar). In this case, from the
“GDI”
menu, choose
“MCU Configuration”
and verify that the hardware code is set correctly.
8.
Make sure the target microcontroller is working. Programming and
debugging rely on a BDM communication between the “USB to BDM”
interface and the target microcontroller. This means that, in order to
work correctly, the target microcontroller must be running. In particular,
make sure that:
On ZK-S12(X) Series Starter Kits, the target microcontroller is
correctly inserted in the ZIF socket;
On ZK-S12(X) Series Starter Kits, the
“VDD SEL”
jumper in the
“POWER SUPPLY”
section selects the appropriate voltage for the
specific microcontroller you are working with;
The oscillator circuitry is working according to the microcontroller
specifications.
9.
For other problems, please refer to your Starter Kit’s specific user’s
manual.
