Debugging on SPARC and SPARClite targets
gdb needs to know the following specifications to talk to your SPARC or Fujitsu SPARClite.
Use one of the following gdb commands to specify the connection to your SPARC target board.
target sparclite serial-device
To run a program
on the board, start up gdb
with the name of your program as the argument. To connect to the board,
use the command target
sparclite serial-device,
where serial-device
is the name of
the serial port connected to the board. If the program has not already
been downloaded to the board, you may use the load
command to download it. For example, the following sequence connects to
the target board through a serial port, and loads and runs a program called
prog
through the debugger.
(gdb) target sparclite com1 [SPARClite appears to be alive] breakinst () ../sparcl-stub.c:975 975 } (gdb) s main () hello.c:50 50 writez(1, “Got to here\n”); (gdb)
target sparclite hostname:
portnumber
You can specify
a TCP/IP connection instead of a serial port, using the syntax, hostname:
portnumber(assuming
your sparclite
board is connected
so that this makes sense; for instance, to a serial line managed by a terminal
concentrator).
gdb also supports set remotedebug n to allow you to see some debugging information about communications with the board by setting the variable, remotedebug.
