Ok, in any case this binary may not work.
linker knows that .data section is to be loaded in ram from flash in
init step.

In the map file, LMA awareness is explicit at the start of .data:

.data           0x00800060      0x5dc load address 0x00007ca2

but at:

                0x0080063c                _edata = .

there's no sign that ld is looking much past VMAs.

linker should know that image of section .data exceeds limit of test
memory region
