about platform and commands.

@kindex target jtag
|

@item target jtag jtag://@var{host}:@var{port}
|
||||
|

Connects to remote JTAG server.
|
||||
JTAG remote server can be either an or1ksim or JTAG server,
|
||||
connected via parallel port to the board.
|

|
||||
Example: @code{target jtag jtag://localhost:9999}
|

@kindex or1ksim
|

@item or1ksim @var{command}

If connected to @code{or1ksim} OpenRISC 1000 Architectural

Simulator, proprietary commands can be executed.
|

@kindex info or1k spr
|

@item info or1k spr
|

Displays spr groups.
|
||||
|

@item info or1k spr @var{group}
|
||||
@itemx info or1k spr @var{groupno}
|

@itemx spr @var{groupno} @var{registerno @var{value}}
|

@itemx spr @var{registerno @var{value}}
|

Writes @var{value} to specified spr register.

@end table
|
||||
|
||||
Some implementations of OpenRISC 1000 Architecture also have hardware trace.
|
||||
It is very similar to @value{GDBN} trace, except it does not interfere with normal
|
||||
program execution and is thus much faster. Hardware breakpoints/watchpoint
|
||||
triggers can be set using:
|
||||
@table @code
|
||||
@item $LEA/$LDATA
|
||||
Load effective address/data
|
||||
@item $SEA/$SDATA
|
||||
Store effective address/data
|
||||
@item $AEA/$ADATA
|
||||
Access effective address ($SEA or $LEA) or data ($SDATA/$LDATA)
|
||||
@item $FETCH
|
||||
Fetch data
|
||||
@end table
|
||||
|
||||
When triggered, it can capture low level data, like: @code{PC}, @code{LSEA},
|
||||
@code{LDATA}, @code{SDATA}, @code{READSPR}, @code{WRITESPR}, @code{INSTR}.
|
||||
|
||||
@code{htrace} commands:
|
||||
@cindex OpenRISC 1000 htrace
|
||||
@table @code
|
||||
@kindex hwatch
|
||||
@item hwatch @var{conditional}
|
||||
Set hardware watchpoint on combination of Load/Store Effective Address(es)
|
||||
or Data. For example:
|
||||
|
||||
@code{hwatch ($LEA == my_var) && ($LDATA < 50) || ($SEA == my_var) && ($SDATA >= 50)}
|
||||
|
||||
@code{hwatch ($LEA == my_var) && ($LDATA < 50) || ($SEA == my_var) && ($SDATA >= 50)}
|
||||
|
||||
@kindex htrace
|
||||
@item htrace info
|
||||
Display information about current HW trace configuration.
|
||||
|
||||
@item htrace trigger @var{conditional}
|
||||
Set starting criteria for HW trace.
|
||||
|
||||
@item htrace qualifier @var{conditional}
|
||||
Set acquisition qualifier for HW trace.
|
||||
|
||||
@item htrace stop @var{conditional}
|
||||
Set HW trace stopping criteria.
|
||||
|
||||
@item htrace record [@var{data}]*
|
||||
Selects the data to be recorded, when qualifier is met and HW trace was
|
||||
triggered.
|
||||
|
||||
@item htrace enable
|
||||
@itemx htrace disable
|
||||
Enables/disables the HW trace.
|
||||
|
||||
@item htrace rewind [@var{filename}]
|
||||
Clears currently recorded trace data.
|
||||
|
||||
If filename is specified, new trace file is made and any newly collected data
|
||||
will be written there.
|
||||
|
||||
@item htrace print [@var{start} [@var{len}]]
|
||||
Prints trace buffer, using current record configuration.
|
||||
|
||||
@item htrace mode continuous
|
||||
Set continuous trace mode.
|
||||
|
||||
@item htrace mode suspend
|
||||
Set suspend trace mode.
