“Unknown Bitporter pod SDK error code! Unable to decode. (-2130669553)”
The full error message, usually mixed in with some other PROGRAM ERROR messages:
PROGRAM ERROR: Error detecting local Bitporter pods: Unknown Bitporter pod
SDK error code! Unable to decode. (-2130669553)
Most of the time, if this is reported it means both the Bitporterʹs USB cable and the dedicated
DC power cable are connected to the Bitporter. One or the other must be disconnected.
The Bitporter is only able to pay attention to either the USB connection or the Ethernet
connection.
While the dedicated DC power cable is connected to the Bitporter (and its power is on), the
Bitporter ignores the USB interface and only utilizes the Ethernet interface, even if the
Ethernet cable is not connected.
The USB interface is only used when the dedicated DC power connection is not used. (The
Bitporter is able to draw sufficient power over the USB interface, and must be connected to a
powered USB port for USB to work correctly.)
See the beginning of Chapter 3 for more details.
Note:
If this problem is still reported after the USB/Ethernet/Power cables are properly attached, please
contact Achronix Technical Support.
