SD Card - Autoconfig

Table of Content

OpenIPC can be autoconfigured throw an SD Card. This is particularly usefull for IPC with Wifi Only where UART is not acessible. This mecanism is managed by automount.sh.

The camera need a SD Card slot for this porpose.

Preparing the SD Card

The SD Card must be formatted in FAT/FAT32/vFAT with at least one partition. This is the commands on Windows (all data will be deleted) :

diskpart

list disk
select disk <number corresponding to your SD Card>
clean
create partition primary
format quick fs=FAT32
list partition
active
assign letter=<letter>

Inserting files to be replaced on the ipc

Corresponding code of automount.sh

    # copy files from autoconfig folder
    [ -d "${destdir}/$1/autoconfig" ] && cp -afv ${destdir}/$1/autoconfig/* / | logger -s -p daemon.info -t autoconfig

Create a folder autoconfig and insert the file at the destination path to be copied in OpenIPC.

<sdcard-path>/autoconfig/<path to file>/file will be copied to /<path to file>/file

example :

<sdcard-path>/autoconfig/etc/init.d/interfaces

will be copied to

/etc/init.d/interfaces

Inserting a script to be run only once

Corresponding code of automount.sh

    # execution of the specified commands one time
    [ -f "${destdir}/$1/autoconfig.sh" ] && (sh ${destdir}/$1/autoconfig.sh ; rm -f ${destdir}/$1/autoconfig.sh) | logger -s -p daemon.info -t autoconfig

Create a shell script at root of the SD Card named autoconfig.sh. The content of this script will be run, then the file removed.

Inserting a script to be run each startup

Corresponding code of automount.sh

    # execution of the specified commands
    [ -f "${destdir}/$1/autostart.sh" ] && sh ${destdir}/$1/autostart.sh | logger -s -p daemon.info -t autostart

Create a shell script at root of the SD Card named autostart.sh. The content of this script will be runned at each startup.
