i210 SDP interrupt

[AMamo1]

Hi!

We are developing E620-based controller using WGI210IS chip. One of the tasks - getting of interrupt when signal on SDP0 pin appears.

I try to do the following:

1) check that SDP0_IODIR bit of CTRL register set to 0 (input);

2) set SDP0_GPIEN bit of CTRL register set to 1 (interrupt enabled);

3) attach interrupt handler to interrupt number associated with i210;

- but nothing happened. I am sure that signal on SDP0 appears with 1Hz freq (checked with oscilloscope and by polling SDP0_DATA value) and that interrupt handler attached properly (when network cable connected I can see interrupts created by network activity).

What have I missed?

PS. OS - QNX 6.5SP1.

Hello, Carlos.

Actually, I already solved this. I didn't noticed that the device driver has put the i210 into the MSIX mode, so I just was waiting interrupt on the wrong vector. My bad. Sorry to have bothered you.

Alex.
