    _______________________________________________________

Details:

When writing to flash avrftdi uses an intermediate buffer to construct the
data stream which gets send to the AVR. To construct that stream, a pointer to
the data to be programmed is maintained by avrftdi and is initialised to
m->buf by avrftdi_flash_write() (Which programs a flash page in the AVR).
So every page is programmed with the first page_size bytes of the memory
image.
The correct initialisation should be: &m->buf[addr].

Patch is attached.
