Added a check for FMT_IMM in update.c:do_op() when trying to write to an "immediate" file format.

Well, "immediate mode" means that instead of providing a filename, you provide the actual data тик which can only be a single byte.

For output, immediate mode doesn't make any sense at all.

I'm leaving the bug report open, as for writing, it should
simply tell that immediate mode is illegal.

I am using AVRISP MKII with latest LUFA firmware, and reading fails if I choose "immediate mode" for output file format :

sudo avrdude -v -c avrispmkII -p m1284p -B 100 -U flash:r:output.bin:m

However, it reads okay if I select some other output file formats: raw (r), hex (i), moto (s) . Sadly, even at max verbosity levels (-vvvvvv....) I can't get more output information than:

Reading | ################################################## | 100% 431.89s

avrdude: writing output file "output.bin"
avrdude: fileio: invalid operation=1
avrdude: write to file 'output.bin' failed

then it exists with FUSES OK and tells "Thank you".

Why I am getting this problem, and how it could be fixed?

P.S. same problem happens with other memory types, not just flash: also, eeprom, fuses memory, etc., so this problem is not memory dependent. Instead, it depends ONLY on output file format, immediate mode = fail
