thanks Paul,

I made a great mistake! I was very surprise because I have already received multicast packets.
But here, the first message was on the PTP event port(319), and the second was on the PTP general port(320). And I was just listening to event port.
So I have to use 2 fifos and it works well ...

hello,

I have to listen to a PTP server on MOD5234. My problem is that the PTP server sends two messages seperated only by a few ms.
I read a message from Stephan posted on april 16th,2010 and I tried to use 2 file descriptors on the same port (multicast.cpp modified and system files rebuilt).
The ...

Thanks Larry,

I learned something about IRQ7 : it works like NMI!
So I would rather use other interrupts (IRQ1, 3 and 5).
Thank you for the lesson,

thanks Larry,
But there is a mistake somewhere:
I use IRQ7 but if take a look at my SetInc(.....,7,4,4.) you could see that I use the vector 7 with level and priority to 4.
I made an un-maskable interrupt (0x2700) but the same code with IRQ5 in place of IRQ7 works with no trap, why??

thanks for the ...

My application has one external Interrupt IRQ7 every second (no timer).
A trap occured up to 3 times in a day, in OsIntCtxSw (address 200DEF0 in the map) offset 0x1A (Faulted PC = 0200DF0A)
During three days the same application without IQ7 interrupt had no trap.
I added below the trap text, IRQ ...
