Section configuration (contents set in the [GNU17 Linker Script Settings] dialog box)
These are the contents set by default.
The VMAs (execution addresses) are set so that the
.bss
section is located from address 0x0 (RAM) and the
.vector
section (
.rodata
section of
boot.o
) is located from address 0x8000 (start of ROM). Other sec-
tions are located at addresses following these two sections. Since sections other than
.data
are used from their
stored addresses, no LMAs (load addresses) are set. Since
.data
is copied from ROM to RAM before use, a
LMA is set following the
.rodata
section. The memory map configuration in Figure 5.7.6.2 can be realized
directly, without modifying this section configuration.
