Fw: Header files for x2618 and compile error

[TonyB-2]

Some parts of this message have been removed. Learn more about Nabble's security policy.

I'm using mspgcc for programming an x2618 mcu. I've had to make a few changes to the header files for this chip. Below is the diff for these files, compared to a CVS snapshot from just minutes ago, and I'll attach these files as well in case the server doesn't strip them. If someone could review these and put these in CVS I'm sure they may be useful to others.

 

Also, I'm trying to compile the new CVS code, and I'm having a problem compiling Insight/GDB. I've had this problem for a while now, and have just been ignoring it.

gcc -DHAVE_CONFIG_H     -DPROFILE=1 -DWITH_PROFILE=-1
-I. -I. -I../common -I  run.o libsim.a ../../bfd/libbfd.a
../../opcodes/libopcodes.a  ../../libiberty/libiberty.a -lnsl
libsim.a(sim-load.o): In function `LSSEXT32':
../common/sim-n-bits.h:180: undefined reference to `sim_io_error'
libsim.a(sim-load.o): In function `MSSEXT32':
../common/sim-n-bits.h:196: undefined reference to `sim_io_error'

 

I'm not dead without Insight, but it would be kind of nice. I used to use DDD with GDB when I was working on x4618 chips, but I've just been using the MSPGCC downloader with a USBFET for the x2618 chips. I wouldn't mind trying to get a debugger running again.

 

Thanks,

 

TonyB

  I've taken the freedom to convert your patch to a unified diff format, so
it's easiest to read and apply.

Hi Tony;

Thanks for posting these.  This comes at an ideal time for me since I'm just starting a new '2618 based project.

I'm still a bit confused about emulator support for this processor though.  I've been having trouble getting gdbproxy to work with this chip and was under the impression that it wasn't yet supported.

Can anyone tell me what the status of support for the '2618 processor is with gdbproxy?  Does this work in Linux, or Windows only?  If there's a more recent version of the gdbproxy executable then what's on source forge, can someone post a link to it?

Thanks,
Steve
