[microblaze-uclinux] OPB Ethernet Lite sleeping until internal ping

[Giulio Mazzoleni <giulio.mazzoleni@xxxxxxxxxxxxxxxxxxxxxx>]

Hello folks.

I'm using EDK 9.2i and latest OPB 10/100 Ethernet MAC Lite core (version
1.01b).

I started by editing the hardware project
Xilinx-Spartan3E1600-RevA-edk91 included in the release of Petalinux
http://developer.petalogix.com/downloads/petalinux-v0.30-rc1.tar.gz and
replacing the included Ethernet MAC core with the corresponding Lite
version. After that i recompiled the uClinux kernel to support that.

After boot I cannot ping/telnet/ftp to the board until i issue a ping
from the board itself via serial line (for example to the broadcast
address xxx.xxx.xxx.255) and then everything starts working as expected.

Everything works fine when using the full version of the EMAC core. 

Has anybody else encountered this issue or am I missing something?

I'm attaching to http://79.14.157.43/giulio/ping-ethernet-logs.zip the
wireshark logs relative to both the full and lite emac cores.

Many thanks for your time.

Best regards,
Giulio Mazzoleni
