I'm having problem at making my personal project work on real hardware due to data alignment problems; due to the way the hardware works, the images must by 16-bit aligned.
I have tried to specify the alignment through the '.align' directive:
.text
.align 2
.globl _vg_lecturehall
.globl _vg_sylvie_giggle
.globl _vg_club
_vg_lecturehall:
.align 2
.incbin "build/lecturehall.apg"
_vg_sylvie_giggle:
.align 2
.incbin "build/sylvie_giggle.apg"
_vg_club:
.align 2
.incbin "build/club.apg"
But, as can be seem by the memory map, the data is still placed at odd addresses:
.text 0x000000000200aa00 0x12aac build/generated_images.o
0x000000000200aa00 _vg_lecturehall
0x0000000002012d11 _vg_sylvie_giggle
0x0000000002014f2b _vg_club
Does anyone have any idea of what is being done wrong? Is there a way to ensure that a included binary is positioned at an even address?
You are placing your labels BEFORE the .align directives. At that point, there is no particular alignment in effect - it will depend on whether the preceding .incbin generated an odd or an even number of bytes. Move the labels down one line, so that you are actually labeling the included data.
