In the case that we quit without actually having opened a device this would dereference a NULL pointer, so check the device before doing so. Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
= CDBA control tool
The CDBA control tool is used for remotely booting images on development boards
attached using a CDB Assist [https://github.com/sonyxperiadev/CDB-Assist] or Conmux.
= Dependencies
sudo apt-get install libudev-dev libyaml-dev for debian systems
dnf install systemd-devel libyaml-devel for fedora systems
= Device side
On the host with the CDB Assist or Conmux attached the "cdba-server" executable is run
from sandbox/cdba/cdba-server. Available devices are read from $HOME/.cdba
= Client side
The client is invoked as:
cdba -b <board> -h <host> [-c <power-cylce-count>] boot.img
<host> will be connected to using ssh and <board> will be selected for
operation. As the board's fastboot interface shows up the given boot.img will
be transfered and booted on the device.
The board will execute until the key sequence ^A q is invoked or the board
outputs a sequence of 20 ~ (tilde) chards in a row.
If the optional -c is given, the board will upon receiving the tilde sequence
restart the board the given number of times. Each time booting the given
boot.img.
== Device configuration
The list of attached devices is read from $HOME/.cdba and is YAML formatted.
=== Example
devices:
- board: db2k
cdba: 00000001
name: "DragonBoard2k"
fastboot: abcdef1
voltage: 8000
- board: mtp2k
conmux: mtp2k
fastboot: abcdef2
fastboot_set_active: true
- board: evb2k
console: /dev/ttyUSB0
fastboot: abcdef3
fastboot_set_active: true
