It works! :)

set repository option

$ rm main.cpp
$ moco c -r https://developer.mbed.org/teams/mbed/code/mbed_blinky/ -q -b ST-Nucleo-L476RG -o /Volumes/NODE_L476RG

my mbed board works blink! :)

about .mocorc

moco read rc files ./.mocorc & ~/.mocorc

recommend setting is

# ~/.mocorc
options['username'] = 'hotchpotch'
options['password'] = keyring

# ./.mocorc
options['output_dir'] = '/Volumes/NODE_L476RG/'
options['platform'] = 'ST-Nucleo-L476RG'

use developer.mbed.org repository

1. Your repository change status publish
2. hg get https://your_repos...
3. cd repos
4. moco c

It works!
