Troubleshooting with software

EXPLANATION
Use this command to display MVB-Asic counters and the device status of the
configured slave.
The counters keep track of the following variables:
EXAMPLE
The variables are listed in the following way:
dbg>get_stat
MVB_Status
device_address 0064
device_status 5780
My Device
Address
MVB module’s own device address.
My Device
Status
MVB module’s own device status.
Hardware name Version of the Asic chip - Medium - FPGA version.
Software name Module name - Base Line - Project options - Patch release number.
t_ignore The time between master frame and slave frame before RTI (Reply
Timeout Interrupt) occurs.
Line A Errors Number of transmission errors occurred when line A was active.
Line B Errors Number of transmission errors occurred when line B was active.
Heartbeat Internal counter. This counter provides an easy way to recognise module
reset e.g. during a long test.
Macro Period
Counter
Number of macro cycles.
All Frames Number of received frames.
Erroneous
Frames
Number of erroneous frames.
Asic re-started In error situations (bus silence) MVBC Asic is set to configuration mode
and then back to full operation mode. This counter keeps track of these
"mild resets."
DC/DC
conversion
errors
If there is a fault in the DC/DC converter and it is reset, mild reset is also
performed on MVBC Asic.
Bus Status OK or BAD. Cables disconnected or incorrect termination.
Lines Line mode (slm = single line mode, red = redundant line mode), line
condition (both A and B, 0 = bad, 1 = ok), active line (A or B).
List of Devices List of known devices’ addresses and their device statuses. If the status
is unknown, the following is displayed:
????. If the device in question is
a bus administrator,
BA is displayed
