Hi,
I am facing a problem with atmega128A. When I try to dump the atmega128 compiled code on to atmega128A my LCD program don't work. I have tested the code in proteus and it works fine. The same hex file was dumped on atmega32 and it is also working. But it donot work on atmega128A.
Is there any difference in atmega 128 and 128A. Do any one have faced the similar problem. Also is this the problem of compiler. I tried reinstalling the compiler but the same problem occurs.
Winxp under virtual box
crystal 7.32800Mhz
avr studio 4
winavr gcc latest |

| Does the 128A have a M!)# compatibility fuse? If YES, is it programmed? |

Timer function not working properly? Check CLKDIV8 Fuse first

Could that be M103C perhaps? |

| I need to check this. M103C must be atmega103 compatibility mode? If yes then I will reply soon once i confirmed. But the issue is that avr studio allows atmega128A for assembly only. Also I am using USBASP programmer. Thus the free software don't have atmega128A settings. |

In case you have not realised.
You remove the M103C fuse.
You choose mega128 as your target AVR for both avrdude and avr-gcc.
Ignore the A in mega128A.
David. |

Yes i removed the fuse. But same problem. I want to clear that when i compile the code with m32 settings and dump the generated hex file on m128A the LCd works fine.
Now when I compiled in m128 settings and disabled the m103c fuse lcd screen line1 just show black boxes.  . I am very much fed up. Have not faced such problem before. |

| I am using 4.18 ver of avr studio. I uninstalled it and downloaded the 4.19 ver. This version suppose to have avr128A support. But i am getting wierd erros with 4.19. I am not able to compile the code.
Code:
rm -rf avr128a.o avr128a.elf dep/* avr128a.hex avr128a.eep avr128a.lss avr128a.map
Build succeeded with 0 Warnings...
mmcu=atmega128a -Wall -gdwarf-2 -std=gnu99 -Os -funsigned-char -funsigned-bitfields -fpack-struct -fshort-enums -MD -MP -MT avr128a.o -MF dep/avr128a.o.d -c ../avr128a.c
/usr/bin/sh: -Wall: command not found
make: [avr128a.o] Error 127 (ignored)
mmcu=atmega128a avr128a.o -o avr128a.elf

make: [avr128a.elf] Error 127 (ignored)
avr-objcopy -O ihex -R .eeprom -R .fuse -R .lock -R .signature avr128a.elf avr128a.hex
avr-objcopy: 'avr128a.elf': No such file
make: *** [avr128a.hex] Error 1
Build failed with 1 errors and 0 warnings...
winavr gcc is latest i think version 10. why such errors. |

4.19 has stopped looking for WinAVR so you have to manually edit the project options to tell it where make.exe and avr-gcc.exe are located:
Code:
root@ws-czc1138h0b:/windows/WinAVR-20100110# find . -name avr-gcc.exe -or -name make.exe
./bin/avr-gcc.exe
./utils/bin/make.exe

| Thanks clawson. code compiled without errors. I will be checking whether it works on lcd. Will reply soon. But the problem is m128A is only for assembler in 4.19 also. |

GREAT ,
IT worked. avr studio 4.19 works for m128A. Thanks. Also i disabled the m103c fuse. Dont know what exactly the problem was. I think new make file generated the code properly. Any body who is suffering with this error please install avr studio 4.19.
Thanks to all who helped me. " david.prentice" Thanks a ton. Clawson U Rock ! . Guys i really mean it i was facing this error from lat four days.
AVRFREAKS is a awesome site.
Regards,
Pratik .R. Bhagat |
