I have reserved memory using .word :
var1:
.word 0
:
and then tried to save to it using :
LDR R3, =var1
STR R2, [R3]
:
but this doesn't work (R3 loads address of var1 correctly, but contents of R2 not written to memory) and causes an ImpreciseErr.
Can someone give me some pointers on why this doesn't work since allocating and saving to memory is a basic yet essential operation in assembly language programs.
Thanks.
