[BEGINNER LEVEL]: C6678 - SRIO and Doorbells

Hi,

This is my first post in the TI community. I'm a totally new beginner using the TI products. I'm working with C6678 DSP and SRIO in a multicore environment. Currently using an evm6678 board with SRIO in loopback mode I'm sending data for one core to another inside the board, where to perform such sending I did use of the TI SRIO driver with sockets for type11 packes. Now what I want to do is to notify the receiving side that the data is there by means of doorbells, which are ground on DIO sockets, in fact my idea is send a doorbell to action an ISR. My main problem is the more I read about the topic the less I understand, I've been reading several posts into the community and also the SRIO Driver and SPRUGW1A documentation. The lack of examples it's also a problem, I've been digging into the DIO loopback mode example, but  unsuccessfully. Any help would be more than welcome.

Thanks,
Jorge
