Hello Madhu,

Can you please elaborate over what you really want to do? and using what? are you using Debian OS - Sys/BIOS or StarterWare.

I am still a rookie, but I can suggest the following link:

Hope it helps.

Hi Rathin,

Thank you so much for your response.

Basically I am trying to enable interrupts of UART2 on beaglebone black, what are all the register i have to configure to work interrupts work properly.

I am kernel newbie, I started “free-electrons device driver development” course, as part of the course I have to enable interrupts on UART2, using USB to serial cable connect the pins of UART2 open the piccom terminal and if I sent some characters on the UART2 console( picocom) interrupt should be triggered and ISR needs to be called.

But I don’t know what are the all the registered needs to be configured.

I am not using debian OS, I downloaded latest 4.9.y kernel and compiled my self and loaded that kernel. and I am using ubuntu 14.04 rootfs.

Any help is appropriated.

Thanks in advance.

Regards,
Madhu

I have not worked on kernel 4+ and not on Ubuntu but I am pretty sure its the same for Ubuntu as it is for Debian, so give it a shot!
