upload_port is not honored without a framework specified

[countrodrigo]

The upload_port environment option doesn't seem to be honored when not using a framework. Here is my platform.ini:

[env:arduino_pro5v]
platform = atmelavr

#framework = arduino
#board = uno

board_mcu = atmega328
board_f_cpu = 16000000L

upload_protocol = arduino
upload_port = /dev/cu.usbmodem1451
upload_speed = 115200

targets = upload

If I use the framework and board options that are commented instead of the direct settings, it works just fine.

The avrdude command it tries to run is:
/Users/countrodrigo/.platformio/packages/tool-avrdude/avrdude" -v -p atmega328 -C "/Users/countrodrigo/.platformio/packages/tool-avrdude/avrdude.conf" -c arduino -b 115200 -D -U flash:w:.pioenvs/arduino_pro5v/firmware.hex:i
This is missing the -P option. If I run that command manually and pass the -P /dev/cu.usbmodem1451, then it can program the device just fine.

Thanks for the report, I see this bug. However, this issue isn't linked with missed framework option, but with missed board option. Try to specify similar board to you hardware which is listed in platformio boards.

Please re-test it in the latest develop version http://docs.platformio.org/en/latest/installation.html#development-version

@ivankravets Seems to be se same problem when using target = program or -t program. As @countrodrigo says the -P argument is missing. If I use upload_flags to specified the upload port everything works as expected.

[env:attiny85]
platform = atmelavr
board = attiny85
board_f_cpu = 8000000L
framework = arduino
targets = program

upload_protocol = buspirate
upload_speed = 115200

; do not works
upload_port = "/dev/cu.usbserial-A7036H51"

; works
upload_flags = "-P/dev/cu.usbserial-A7036H51"

People don't like to read documentation http://docs.platformio.org/en/latest/platforms/atmelavr.html#upload-using-programmer

[alexbonhomme]

People don't often like this kind of comments too.

The documentation isn't that obvious (as you think it is). There is some examples with the -P flags, others without and others with -P and -b one. There is not clear explanation saying that the upload_port doesn't work as expected.

I would do a PR about it. Thanks for your help.
