How to identify the sd card connected to Edison board.

I want to take backup state from emmc to sdcard and restore data to sdcard.

Intel Edison(arduino expnasion) board and Firmware Version:159.devkit

Adruino IDE 1.6.8 on ubuntu 14.04

Please provide complete processes for backup and restore the sate.

Hello Sreenivas,

I can't answer all of your questions but there is one I can because in my app I also face to this problem. here is an example if you want to konw if your sd card is connected :

bool mounted = false;

bool sdPresent = false;

for (;;) {

//cout << system("date") << endl;

ifstream f;

f.open ("/dev/mmcblk1");

if (f.good()) {

f.close();

if (!mounted)

{

system("mount /dev/mmcblk1p1");

mounted = true;

}

sdPresent = true;

}

else {

f.close();

sdPresent = false;

mounted = false;

}

}

When your sd card is connected, the the file named "mmcblk1p1" should be visible in the repertory /dev of the edison system and not if your sd card is not connected.

I hope I helped you.

Hi,

If you're looking to backup your Edison you can use the dd command as explained here http://www.instructables/id/BackupRestore-Intel-Edison/?ALLSTEPS www.instructables/id/BackupRestore-Intel-Edison/?ALLSTEPS . Make sure to follow the warnings in the link to avoid losing data in your image so that your backup is done successfully.Sergio
