Hi,
This is quite a helpful summary of how to get started with gdb, at least as far
as you have come so far. I haven't yet had a chance to try it myself, but I've
used gdb on other embedded micros. The problem is the "run" command - that
simply does not work with gdb and embedded systems. When doing native
debugging on a PC, the "run" command is used to tell the OS to create a new
process, to do whatever load-time linking is required, and to generally start
the program going. On an embedded system, this is not relevant. But since the
program is already to run (after downloading), it is just a matter of using the
"continue" (or "c") command. You might need to check that the pc is set to the
correct point before continuing - it may even be a good idea to reset the
target from within gdb before doing "continue" - as I say, I haven't tried it
myself yet to find out the idiosyncracies.

Hi,
I am using MSP430 microcontroler with the gnu C.
*) First I have test insight-5.1.1, the problem is that when I start
configure with --target=msp430, this does not run. I have edit the source of
configure and in fact there is nothing about the msp430. I have search in the
source around and nothing.
*) After I have use insight-5.2.1, the problem is the same as with 5.1.1
*) I have get the gdb source from sourceforge release 5.1.1, and this release
include the msp430. The compilation was ok, I have my exec file msp430-gdb.exe
and msp430-run.exe in the /usr/local/msp430 dir.
*) After that I have get the rproxy20021030.exe and the setup files with dll
to install gvieo on my computer.
After installation of the driver for the Texas FET (gvieo...), I start
rproxy like this : rproxy --debug --port=8888 msp430 &
I have this message :

notice: rproxy-20021030.exe: waiting on TCP port 8888
This is the right micro, I presume that the rproxy program communicate with
FET
*) After that I run the debuger (I have compiled my sources with the -g flag
I do not strip when linking) : msp430-gdb a.out
I enter this command under gdb :
(gdb) target msp430 pc_ber:8888 (my pc name is pc_ber)
(after a while...) Timeout reading from remote system.
(gdb)
If I use the command target remote pc_ber:8888 the reponse is
(gdb) target remote pc_ber:8888
Remote debugging using pc_ber:8888
0x0000fc40 in __pack_f (src=0x121)
(gdb)
On the rproxy software I have this message :
info: msp430: Target device is a 'MSP430F135' (type 4)
notice: rproxy-20021030.exe: waiting on TCP port 8888

*) This is the start of the main code :

43 unsigned char mode;
44 double ret = 0;

46 pnt_timeout = &TIME_OUT_MB;
47
48 // First initialization after
49 WDTCTL = WDTPW + WDTHOLD; // Stop watchdog timer
I put a break at line 46 :
*) When aI run the program :
(gdb) r
Starting program: /cygdrive/c/usr/ber/msp430/rf868/a.out
Don't know how to run. Try "help target".
If you have some comments, I will apreciate them
Thank you
Bernard.

Hello,
I have some problems using GDB with my Win 2$$$ / Cygwin system, and I
must go forward with my project.
Is it possible to convert the a.out file to a file like file.d43 to be
used by the C-SPY debuger ??
Thank You
