Querying the Availability of Connected Pods (-q option)
The Bitporter pod query mode is used when multiple Bitporter pods are visible to the host
running acx_stapl_player. This mode returns the current state of all connected pods (whether
in use or not).
Important! It is recommended that this query mode not be the only means used to synchronize multiple
users' attempts to use multiple pods — users still need to ensure that a given target board is not being
used through another non-Bitporter interface before using the Bitporter attached to that target board.
To see a list of the pods currently auto-detected by acx_stapl_player, run the following at the
command-line:
acx_stapl_player -q
This command returns to the command-line a table of the currently detected pods, using the
following criteria:
• USB-connected Bitporter pods: Pods connected to the host are listed by name in the
first column only if they are currently not in use by another instance of
acx_stapl_player. Pods connected to the host via USB which are already in use are not
be listed. Pods connected to other hosts via USB are not listed, regardless of usage
state.
• Ethernet-connected Bitporter pods: All Bitporter pods connected on the same subnet
as the host are listed by name in the first column. The second column contains the
owner of each pod found. A listing of
<available>
means the pod currently has no
owner (and is available for immediate use). A listing displaying an IP address means
the pod is currently in use by a host located at that IP address.
For example, if two pods with serial numbers 12345 and 12346 are connected to the same host
via USB, and two additional pods with serial numbers 12347 and 12348 are connected via
Ethernet on the same subnet, then run the acx_stapl_player in query mode:
acx_stapl_player -q
The command returns:
