@end table
@node OpenRISC 1000
@subsection OpenRISC 1000
@cindex OpenRISC 1000
@cindex or1k boards
See OR1k Architecture document (@uref{www.opencores.org}) for more information
about platform and commands.
@table @code
@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.
@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.
