Hi,
Is there a captured working example of an Ethernet Boot Packet? Any example with at least the first 62 bytes? Knowing the entry address, count, and load address would be helpful. I think our setup is ordinary (little endian 6678).
My TMDXEVM6678L is transmitting Ethernet-Ready Announcement frames. Our equipment is transmitting Ethernet Boot Packets to it. They comply with SPRUGY5 as far as I can tell, however, they must be invalid because the announcement frames don't stop. (Per SPRUGY5, the first received valid boot packet causes the ready announcement frames to stop.)
Greg
p.s.
If anybody wants to look at it, I included a request packet and my first Ethernet boot packet. I even have a .pcap file, but the forum won't let me attach it.

The Ethernet boot example is provided in the MCSDK (mcsdk_2_00_07_19\tools\boot_loader\examples\ethernet)

Hey Arun,
Thanks for pointing me at the example. It showed me my mistake!
I need to use UDP SRCPORT=1234/DSTPORT=9, not 67/68 I assumed in response to bootP's 68/67.
My question is essentially answered, but I worry UDP ports might change when we use rev2 silicon with no I2C.Where are the Ethernet Boot Paramteter table values (or memory address) documented?
