Hello Murali,

I have a device driver which provides the IOCTL function for the application to interact.

when the application sends the IOCTL CMD_GO, my driver has to toggle a GPIO every 500 m Sec. until a 3 minute timeout occurs or a CMD_STOP IOCTL is received.

I tried the DECLARE_WORK, DECLARE_DELAYED_WORK and also kernel_thread() to meet this requirement with no success.

Could you please show us the code? thanks, Daniel.
