If I change the linker script such that:
```ld
.data :
{
_sdata = ABSOLUTE(.);
*(.rodata .rodata.*)
*(.data .data.*)
*(.gnu.linkonce.d.*)
CONSTRUCTORS
_edata = ABSOLUTE(.);
} > sram AT > flash
_eronly = LOADADDR(.data);
```
```diff

I am able to boot into NSH. It appears the initializer data for the
variables loaded to SRAM from FLASH is not actually getting stored in flash in
the image.
