Hi,
i have been successfully debugging with Eclipse 3.0 and mspgcc unter
W2K. There was one major problem getting it to work:
I found a web site with a description on how to do it. Besides a lack of
explanation of the intended workings, that description was old and
invalid. It seems like, there has been an important change in Eclipse in
that recent versions can make msp430-gdb connect to msp430-gdbproxy
automatically. With old versions you had to include statements in the
gdb.ini file to setup the connection. Now when you use the new Eclipse
with the old ini file, you are really trying to connect to
msp430-gdbproxy TWICE and an error results. It cannot work. So my ini
file looks like this:
set remoteaddresssize 16
set remotetimeout 999999
set download-write-size 512
set remote memory-write-packet-size 512
set remote memory-write-packet-size fixed
set remote memory-read-packet-size 512
set remote memory-read-packet-size fixed
mon reset
The ini file sits in the Eclipse workspace in the same directory as the
elf file. There is no "target remote localhost:2000" command and no
"load ....elf" command.
Loading the elf file to the debugger and to the debugging gui is
automatic in Eclipse, if you select the right binary parser. The
download (jtag programming) is included in a batch file that also starts
up gdbproxy. The default port number is as good as 2000, except you have
to setup eclipse to tell msp430-gdb to use the correct port.
f:
cd f:\programme\mspgcc\bin
msp430-jtag -e f:\programme\eclipse\workspace\...\....elf
msp430-gdbproxy --port=2000 msp430
f:\programme\eclipse is the path where i installed Eclipse.
f:\programme\mspgcc is the path where i installed mspgcc.
Solving the problems took some time and is impossible without studying a
little bit the gdb manual. Eclipse includes a console window where you
can watch some of the data exchanged with the msp430-gdb. You can also
enter commands by hand, e.g. to reset everything.
So the intended connection scheme looks like this:
Eclipse <-> msp430-gdb <-> Socket <-> msp430-gdbproxy <-> Parallel port
<-> JTAG cable <-> MSP430 (DUT)
msp430-jtag AND msp430-gdb AND Eclipse need to read the elf file
Eclipse is something rather impressive. Debugging failed, though, when i
had multiline embedded assembler sequences in my MSP430 source.
