[En-Nut-Discussion] Newbie - Debugging - makefile removes(rm) *.elf file

[Anton Veldhuizen]

Hi guys,

Thanks for your replies.  I solved my coff creation problems by upgrading 
WinAVR to 2004/04/04 (make has been upgraded) and ethernut to 3.4.2 
(makefiles include extended coff).  Accompanied by AVR Studio 4.09, I now 
enjoy a sometimes slow, sometimes crashing (AVR Studio 4.09 bugs) yet 
workable debugging environment.

Regards,
Anton

Hi,

I am using following to produce .cof file. It was used just for a small
piece of code. I never tested it with full Nut/OS.

Also avr-gcc options can be obtained by invoking it with '--help -v' 
options.

-------------------
CFLAGS = -g -Os \
-funsigned-char -funsigned-bitfields -fpack-struct -fshort-enums \ -Wall 
-Wstrict-prototypes \
-Wa,-adhlns=$(<:.c=.lst) \
-std=gnu99

LDFLAGS = -Wl,-Map=$(TARGET).map,--cref,--defsym,__stack=0x10FF


OBJCOPY = avr-objcopy
ELFCOF  = $(OBJCOPY) --debugging \
         --change-section-address .text-0x0 \
         --change-section-address .data-0x800000 \
         --change-section-address .bss-0x800000 \
         --change-section-address .noinit-0x800000 \
         --change-section-address .eeprom-0x810000

%cof: %elf
         $(ELFCOF) -O coff-ext-avr $< $@
