View Source mix upload (ssh_subsystem_fwup v0.6.2)

Upgrade the firmware on a Nerves device using SSH.

By default, mix upload reads the firmware built by the current MIX_ENV and MIX_TARGET settings, and sends it to nerves.local. Pass in a another hostname to send the firmware elsewhere.

NOTE: This implementation cannot ask for passphrases, and therefore, cannot connect to devices protected by username/passwords or decrypt password-protected private keys. One workaround is to use the ssh-agent to pass credentials.

Command line options

• --firmware - The path to a fw file

Examples

Upgrade a Raspberry Pi Zero at nerves.local:

MIX_TARGET=rpi0 mix upload nerves.local

Upgrade 192.168.1.120 and explicitly pass the .fw file:

mix upload 192.168.1.120 --firmware _build/rpi0_prod/nerves/images/app.fw
