Hi experts, I am using MVL6.0 in my project and have customized the kernel as per the requirement. However, i am facing a problem where the Ctrl+C signal doesn't get caught (or not sure if it is even generated) on the target platform. I have tried using the "trap" at the shell to capture the signal but the signal just doesn't get caught. Below is what i have done to try the trap way trap " " INT echo "Catching Ctrl+C signal" trap INT sleep 5 Putting this piece of code into a script doesn't catch the signal SIGINT (ctrl+c). To understand if it was a problem with the shell, i wrote a C code to register my own signal handler for SIGINT signal. To verify the correctness of the code, i executed the C code on the HOST server and it works well there (signal handler gets invoked when ctrl+c is pressed). Whereas, the same C code doesn't catch the Ctr+C signal in the target platform. Can someone tell me if there is any specific way to identify is there a way or rather is there a need to enable the signals explicitly while creating the config file for the kernel? Below is the output of "stty -a" command at the shell where i need to catch the Ctrl+C signal. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ / # stty -a speed 115200 baud; rows 24; columns 80; intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V; flush = ^O; min = 1; time = 0; -parenb -parodd cs8 hupcl -cstopb cread clocal crtscts -ignbrk -brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr icrnl ixon -ixoff -iuclc -ixany -imaxbel opost -olcuc -ocrnl onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0 isig icanon iexten echo echoe echok -echonl -noflsh -xcase -tostop -echoprt echoctl echoke ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Regards, Vijay _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
