Bitporter User Guide www.achronix.com PAGE 17
By default, all Bitporter pods are set up to use DHCP negotiation the first time they are
plugged into an Ethernet network. Since the pod stores its Ethernet configuration in flash
memory, the Ethernet configuration typically only needs to be performed once.
Note: Only pods on the same subnet (without an intervening router) can be automatically detected by
STAPL player (see the -q option, Table 4‐1 , page 24). Use the -p option to connect to pods on non‐
local subnets using the podname containing the IP address of the pod (see Table 4‐1 ).
To connect to a Bitporter pod via Ethernet:
1. Turn off the power to the target system.
2. If the pod is connected to the PC via USB, disconnect the USB cable from the Bitporter.
3. Connect the JTAG flat ribbon cable to the target JTAG pins. The red strip is pin 1.
Note: If the target JTAG connector is not keyed, the target’s User Guide will specify the location
of pin 1 on the target JTAG connector.
4. Connect the JTAG flat ribbon cable to the Bitporter pod. The plug is keyed.
5. Connect the DC power cable to the power outlet and the pod. The Bitporter podʹs
POWER LED should now be on. The podʹs COMM LED should start blinking.
6. Connect the Ethernet cable to the Ethernet jacks on the wall and the pod. Once the Bit‐
porter podʹs COMM LED stops blinking and turns off, the pod has successfully acquired
an IP address.
Note: If the COMM LED does not stop blinking (it should take less than ten seconds), talk to
the network administrator to verify that the Bitporter podʹs MAC address has permission to
connect to the local network, and that the Bitporter pod is connected to the proper Ethernet
network jack.
7. Turn on the power to the target hardware.
8. Continue to “Verifying the Setup,” on page 18.
The pod is now able to be referred to by name as net<serial_number> or
net<ip_address>
. The latter name must be used if pod communication is being attempted
across subnets (see Table 4‐1 ).
Disconnecting the Bitporter Pod
Important! An unpowered Bitporter must never be connected to powered target hardware, or the
Bitporter may be damaged.
To end a programming session and disconnect the Bitporter pod from the target hardware:
1. Wait until acx_stapl_player finishes running.
2. Turn off the power to the target hardware.
3. Disconnect the USB cable for USB‐connected pods, or the Bitporter’s DC power cable
for Ethernet‐connected pods.
If the user desires to continue using the target hardware without the Bitporter:
4. Disconnect the JTAG ribbon cable.
5. Restore power to the target hardware.
Alternately, if it is undesirable to remove power from the target hardware:
1. Wait until acx_stapl_player finishes running.
