Add 'wipe' command to DFU tool #4

Closed microbuilder closed 8 years ago

microbuilder commented 8 years ago

A new wipe command should be added to feather_dfu.py to erase the contents of the Arduino flash section, which may be useful when even a factory reset fails.

Or perhaps factory reset should be updated to kill this section of flash, since that might actually be closer to a factory reset situation???

factory_reset currently only reset the DCT (NVM) to default values, it is useful when DCT causes Application to be hanged up (due to wrong configuration), we can put the device into DFU and still can perform factory reset. Maybe we should rename it to setting reset/nvm reset/dct reset.
The factory reset then can be used to both reset DCT and kill the arduino code

I am OK with either way.

Currently we have this:

$ python feather_dfu.py
Usage: feather_dfu.py [OPTIONS] COMMAND [ARGS]...

Options:
  --help  Show this message and exit.

Commands:
  arduino_upgrade
  enter_dfu
  factory_reset
  featherlib_upgrade
  reboot

Lets changes this to:

factory_reset - Clear DCT/NVM, kill Arduino code, then reset
nvm_reset - Add to clear DCT/NVM, then reset (leaving Arduino code intact)
