Thanks, Chris. I used the DOS window on Win2000 to execute the following commands with the -O2 option as follows:
msp430-gcc grocc.c -O2 -mmcu=msp430x1121 -o grocc.exe // to create *.exe bin code msp430-objcopy -O ihex grocc.exe grocc.hex // to create *.hex code msp430-gcc -mmcu=msp430x1121 -g -O -o grocc.elf grocc.c // to create *.elf file The created *.hex file is 10 kB compared to 21 kB of the *.d43 created by the IAR program. Then I used the IAR debugger to download the *.hex file to the MSP430F1121 mc. The program would not run. If I download the *.d43 file, it runs fine. Have I missed something again? Any suggestions? I followed the instructions on the http://www.mikrocontroller.net/mspgcc.en.htm web page to do the above and run their test1.c sample program. The test1 downloads from the mspgdb GUI interface and runs fine. Then I tried similarly with my grocc program. When I tried to download it to the chip, the message in the status bar said: 'Program stopped at ffff'. Then I hit the download button again and the status bar message said: 'DOWNLOAD FAILED: Invalid download offset: Files/msp430/tools/bin/grocc.elf'. Would it be related to my original problem? I have another question. The 'msp430_insight' is the msp430-gdb GUI type of application. How about the 'msp430_tools'? Should I use the DOS window or something else?

I appreciate your > help. that is written in msp430-libx/doc/doc.txt it disables the function entry and exit code that is generated by the compiler. it is useful when doing inlne assembly only functions and a source of strange bugs if not used carefuly. chris ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Mspgcc-users mailing list Mspgcc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mspgcc-users --- Incoming mail is certified Virus Free.
