@cindex or1k boards

See OR1k Architecture document (@uref{www.opencores.org}) for more information
|

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}
|
||||
Displays register names in selected group.
|
||||
|
||||
@item info or1k spr @var{group} @var{register}
|
||||
@itemx info or1k spr @var{register}
|
||||
@itemx info or1k spr @var{groupno} @var{registerno}
|
||||
@itemx info or1k spr @var{registerno}
|
||||
Shows information about specified spr register.
|
||||
|
||||
@kindex spr
|
||||
@item spr @var{group} @var{register} @var{value}
|
||||
@itemx spr @var{register @var{value}}
|
||||
@itemx spr @var{groupno} @var{registerno @var{value}}
|
||||
@itemx spr @var{registerno @var{value}}
|
||||
Writes @var{value} to specified spr register.

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 $FETCH
|
||||
Fetch data
|
||||
@end table
|
||||
|
||||
When triggered, it can capture low level data, like: @code{PC}, @code{LSEA},
|
||||
@code{LDATA}, @code{SDATA}, @code{READSPR}, @code{WRITESPR}, @code{INSTR}.
|
||||
|
||||
@code{htrace} commands:
|
||||
@cindex OpenRISC 1000 htrace
|
||||
@table @code
|
||||
@kindex hwatch
|
||||
@item hwatch @var{conditional}
|
||||
Set hardware watchpoint on combination of Load/Store Effecive Address(es)
|
||||
or Data. For example:
|
||||
|
||||
@code{hwatch ($LEA == my_var) && ($LDATA < 50) || ($SEA == my_var) && ($SDATA >= 50)}
|
||||
|
||||
@code{hwatch ($LEA == my_var) && ($LDATA < 50) || ($SEA == my_var) && ($SDATA >= 50)}
|
||||
|
||||
@kindex htrace info
|
||||
@item htrace info
|
||||
Display information about current HW trace configuration.
|
||||
|
||||
@kindex htrace trigger
|
||||
@item htrace trigger @var{conditional}
|
||||
Set starting criteria for HW trace.
|
||||
|
||||
@kindex htrace qualifier
|
||||
@item htrace qualifier @var{conditional}
|
||||
Set acquisition qualifier for HW trace.
|
||||
|
||||
@kindex htrace stop
|
||||
@item htrace stop @var{conditional}
|
||||
Set HW trace stopping criteria.
|
||||
|
||||
@kindex htrace record
|
||||
@item htrace record @var{[data]*}
|
||||
Selects the data to be recorded, when qualifier is met and HW trace was
|
||||
triggered.
|
||||
|
||||
@kindex htrace enable
|
||||
@item htrace enable
|
||||
@kindex htrace disable
|
||||
@itemx htrace disable
|
||||
Enables/disables the HW trace.
|
||||
|
||||
@kindex htrace rewind
|
||||
@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.
|
||||
|
||||
@kindex htrace print
|
||||
@item htrace print @var{[start [len]]}
|
||||
Prints trace buffer, using current record configuration.
|
||||
|
||||
@kindex htrace mode continuous
|
||||
@item htrace mode continuous
|
||||

|
||||
|
||||
@kindex htrace mode suspend
|
||||
@item htrace mode suspend
|
||||
Set suspend trace mode.
