AVA200 Console Interface

 

Power On Reset

After a power on reset, console output should appear as showin in Figure 26 console interface: 

(c) 1993 Nemesys Research Ltd.
Device Version 200.0
Firmware Version 1.1
I2C Driver Init... OK
Xilinx Init... OK
ATM Init... OK
SAA7191 Init... OK
SAA7186 Init... OK
C-Cube Init... OK
AD1848 Init... OK
Timer Init... OK
Protocol Init... OK
Scheduler Init... OK

 
Figure 26:   AVA200 Power On Diagnostics.

When the ATM transmission interface is in violation (indicated by the Blue LED permanently on), it is normal for the console output to stop when the ``Protocol Init'' stage is reached. As soon as the violation is cleared console output should continue.

Diagnostics

During normal operation of the unit, console output should contain messages of the following form:

Main menu

Pressing any key will cause the scheduler to be exited and the AVA200 Debug Monitor to be entered. The prompt ``>'' will be displayed. The AVA200 Debug Monitor will display a list of the currently acceptable commands whenever the ``?'' character is typed. The main menu should appear similar to Figure 27. 

Commands:
S  Status
A  ATM Interface Tests
8  SAA7186 Scaler Tests
9  SAA7191 Decoder Tests
C  AD1848 Audio Codec Tests
J  C-Cube (JPEG) Tests
X  Xilinx Tests
I  Probe I2C bus

X
Moves control to the Xilinx sub-menu.
I
Scans all addresses on the bus and reports any devices found.
R
Enters ``Remote Mode'' by restarting the protocol stack and the scheduler.
P
Toggles whether cells received over the ATM Transmission interface will be passed to the protocol stack.
M
Prompts for a 16-bit HEX address and dumps 32 bytes of SRAM or Xilinx registers starting from that address.
T
Resets the TAXI chips of the ATM Transmission Interface.
?
Displays the help menu shown above.

Any other key will cause the response: ``Unrecognized command.''

ATM Interface Tests

When ATM menu is entered, the prompt changes to ``ATM>''. The commands available from the ATM menu are shown in Figure 28. 

Commands:
I  Initialize
T  Transmit Cells
R  Receive Cells

?  Print help message

 
Figure 28:   AVA200 ATM Menu.

The commands have the following effects:

I
Initializes the ATM interface and resets the Rx FIFOs.
T
Transmits test cells over the ATM interface. Test cells have header ``DEADBEEF'', ascending payload, AAL5 length of ``0028'' and AAL5 CRC32 of ``BF671ED0''.
R
Receives and displays cells over the ATM interface.
B
Transmits test cells once a second and displays all received cells. This is intended for use using a fibre loopback.
L
As above, but transmits faster and automatically checks the received cells against the expected test cells reporting any errors.
F
Selects whether to use the transmission interface or the fabric connection (where fitted).
E
Edits the route bytes transmitted when the fabric interface is selected.
?
Displays the help menu shown above.

Pressing ``ESC'' will return to the top-level menu. Any other key will cause the response: ``Unrecognized command.''
