Running update command using system() function

Legato Application Framework
1

Hi there ,
I am trying to run update command to install an application say helloworld using library function → system() but it doesn’t work even the sandoxed is made false .

#########################################
{
char cmd[200];
LE_INFO(“INSTALLING NEW APP\n”);
strcpy(cmd,“/legato/systems/current/bin/update /home/root/helloworld.wp76xx.update”);
LE_INFO(“EXECUTING %s\n”,cmd);
system(cmd);
}
#########################################

Please let me know some pointers to overcome this issue .

is it because there is a space after /home/root?

Hi @jyijyi ,
Thanks for the update . Looks weird but it worked for me as well , The reason for failure cases in earlier try is unknown .
