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
