I would get a wireshark trace and compare the one that works with the one that does not.

"Both Ethernet interfaces, the device it communicates with, and the development PC (with Wireshark) are connected to a common Ethernet switch. I don't know what you mean by "switched or independent mode"." By "switch" he means the same thing as "switch" in you...

I ran a quick test of the example and it works on my system. Running 2.7.3. Initially I had the pins wrong, so I would double check that. I had to look at the silkscreen, since pin 1 is in a different place than I expected.

Does the unmodified example program work?

Do you have anything plugged into the flash card slot?

There's 3 levels of speed for toggling gpio, the 54415 platform has an example, but the concept is the same for any platform:
Pins Class, easiest but slowest
C code programming registers
Assembly code programming registers

There are so many variations it can be difficult. I think if there is any deviation from any reference design I would recommend looking the the Freescale processor manual to determine if they are necessary or not for any particular design. I've had problems before because app notes and docs that cop...

Why not just use the NetBurner board? Exactly what is different than the NetBurner design? I would start there, since if it was identical it seems like there would not be any problem. The freescale processor manual for that device should have the minimum connections. I would guess power, gnd, clk, r...

>I've already done that - It didn't work. This is called from UserMain at startup: Make it simpler. Write a totally new app, then start small and build on it. - UserMain only with a global packet declaration, function to setup packet parameters, function to send and halt. Note that you probably need...

How about setting up the packet ahead of time, so the irq7 only posts the semaphore, and your highest priority task is only a pend and send udp packet? An interrupt will call the scheduler, so after the irq7 returns, the highest task ready to run will run, so you do not have to wait for the task tha...
