Hi and thanks for the info. The Version of msp430-gdbproxy is indeed the
one from ftp.opencall.org with creation date July 22nd 2004. The other
date is only the one I receive as response to "monitor version". I also
checked "monitor vcc" but according to the msp's user's guide the 3.0V
should be enough. I increased it a bit:
>monitor vcc 3.3
>monitor erase info
with the same result:
Could not preserve/restore device memory (12)
I don't understand why.
Best regards

Hi,
Erratic behaviour with the debug tools, especially erasing and writing
flash, is usually due to inadequate power. It is more common with the
flash operations, as they require a higher voltage.
Depending which revision of the FG439 you have, you may need the newer
version of msp430-gdbproxy available at ftp.opencall.org. The current
one is dated July 22nd. However, if you use an older version it should
not give erratic results. It should just say it does not recognise the
device.
Regards,
Steve

Hi everybody,
has anyone some experience with debugging an FG439. The new
msp430-gdbproxy version supports the FG439 by being sometimes (!!!)
able to identify the target (at least after a couple of resets and/or
pulling off and re-plugging the JTAG-interface). But generally the
most frequent responses I'm dealing with are masses of
- "Could not reset device (11)",
- "Could not read device memory (6)" and
- "Could not preserve/restore device memory (12)"
usually followed by debugger's attempts "Trying to regain control of
the target...". In fact I haven't managed to "monitor erase ..."
anything until now. "monitor reset/dump/vcc" seem to work properly
and so do regular gdb commands (as far as target connection is
"stable"). Can anyone tell me what I'm doin' wrong? I have no idea.

SysInfo: I'm working with
- a Linux (S.u.S.E. 9.1) PC (Celeron 233MHz) on a
- msp430fg439 (TI's "Retro-Watch") via
- parallel port JTAG interface (Olimex) using
- the new version of msp430-gdbproxy (build: 2004/04/15 but with the
same version "0.7.1" as the old one!),
- msp430-gdb (basis: gdb 5.1.1)
