Christopher,

The only problem is with your understanding of the INTEL HEX file format.

I don't see any extra 32. This byte (at 12th position in Programmer's buffer) comes from the 2nd line of SDCC hex file.

The first line of SDCC's file indicates that there are only 4 data bytes, starting at address 0000.
The next line (SDCC file) says that it contains only one byte at address 000B

So the programmer's buffer fills space from 0004 to 000A with all FF

I hope this should help you.
