The routine for transferring the program from ROM to RAM should be created within
main.c
.
note : Locating the
.textu1
and
.textu2
sections preceding a
.rodata
section with (for example)
no LMA specified will result in positioning the
.rodata
section behind the end VMA address of
the
.textu2
section. Do not locate any VMA-only sections behind LMA
≠
VMA sections.
