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.

Regards,

Guimficus

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.

Hi IoT_srinivas

 

 

Did you find our last suggestion helpful? Were you able to perform the backup process successfully?
