I can't quite figure out what it's doing wrong but you have :-

for(i=0;i<BUFFER_SIZE;++i)

and then later on

if(i==0 && read_data == 0x42) continue

but by pre incrementing i, it can never equal 0 in the second if statement.

maybe the first statement should be :-
for(i=0;i<BUFFER_SIZE;i++)


Maybe a bit more info on what it's actually doing - as well as what
it's supposed to do may assist?
