Hi,

I am designing BLDC controller taking Application note AVR444. The provided code is for IAR compiler. I use AVR GCC.

Any one ever ported it to GCC? if so please help in this regard.

Or any one can give me the hex of the code, so that i can simulate it which will be helpful for me in development.

    Hai

    somehow i managed to compile AN 444 in IAR, but i cant generate hex file.

    If i select intel-standard output format i get this error

    Error[e133]: The output format intel-standard cannot handle multiple address spaces. Use format variants (-y -O) to specify which address space is wanted

    Can any body help me to clear this error?

    Can you successfully edit/compile/burn/run any other simple avr program? Like make an led go on and off at a designed freq and duty cycle? If so, this proves your program development chain is working.

    The multiple address spaces are flash and EEPROM. Are you initializing the EEPROM in your code?

    Try reading the thread below. It has an attached text file with tips, and lots of tips posted as comments on the thread.

    Porting code from IAR to Avr-GCC

    Surely there is something in the makefile about output file type. Might be as simple as removing the comment symbol?

    To generate a hex-file put this under Options>Linker>Extra options

    -Ointel-extended,(CODE)=C:\whatever\code88.hex
    -Ointel-extended,(XDATA)=C:\whatever\eep88.hex

    and compile

    I am having the same issue, however the answer lhogberg gave did not help me any further.

    I still have this error:
    Error[e133]: The output format intel-standard cannot handle multiple address spaces. Use format variants (-y -O) to specify which address space is wanted

    help?

    Vandi.

     

    You do realise that you are replying to a post that is 8 years old. "lhogberg" has never returned here after that post.
