Details:

Hi,

I updated from version avrdude 4.3 to version 5.0 and I use the butterfly
programmer. 

In version 4.3 the flashing works fine. See output:

$ avrdude -P /dev/ttyUSB0 -p m169 -c butterfly -U f:w:test.bin:a

Found programmer: Id = "AVRBOOT"; type = S
    Software Version = 1.4; No Hardware Version given.
Programmer supports auto addr increment.
Programmer supports buffered memory access with buffersize=128 bytes.

Programmer supports the following devices:
    Device code: 0x75

avrdude: AVR device initialized and ready to accept instructions

Reading | ################################################## | 100% 0.00s

avrdude: Device signature = 0x05941e
avrdude: NOTE: FLASH memory has been specified, an erase cycle will be
performed
         To disable this feature, specify the -D option.
avrdude: erasing chip
avrdude: reading input file "test.bin"
avrdude: input file test.bin auto detected as Intel Hex
avrdude: writing f (168 bytes):

Writing | ################################################## | 100% 0.11s



avrdude: 168 bytes of f written
avrdude: verifying f memory against test.bin:
avrdude: load data f data from input file test.bin:
avrdude: input file test.bin auto detected as Intel Hex
avrdude: input file test.bin contains 168 bytes
avrdude: reading on-chip f data:

avrdude: verifying ...
avrdude: 168 bytes of f verified

avrdude done.  Thank you.


After the update to version 5.0, it goes wrong and I can't flash my board
like in the past. Avrdude shows the following output:

$ /usr/local/avr/bin/avrdude -P /dev/ttyUSB0 -p m169 -c butterfly -U
f:w:test.bin:a

I don't know where the problem is. I hope the informations are enough and
useful.


Thanks and greets
