Re: [avr-gcc-list] ".org" in external asm file

[Keith Gudger]

I've just been dealing with this problem... Here's the method that worked
for me.

In your assembly file:

    .section .sboxes,"ax",@progbits             
    .global  sboxes         ; Prototype 

sboxes:
  .byte ...

In your make file:
override LDFLAGS       =
-Wl,-Map,$(PRG).map,--section-start=.sboxes=0x05f00

and if you want it in a hex file:

%.hex: %.elf
        $(OBJCOPY) -j .text -j .data -j .sboxes -O ihex $< $@
