Is here anyone who had made a working mac driver for the Olimex LPC2378?
In the last 2 weeks, i have edit the lwip project download from this
website. But this project is ported for another PHY chip.
I change it to my micrel PHY chip, but nothing seems to work.
I made a ARP packet by hand to test if my MAC + PHY is working.
But I see nothing on wireshark.

Dear michael,
thanx for your ethernet code.
Are you sure this is the final code for the lpc2378-STK board?
I'm using the board without the LCD, the olimex lpc-p2378.
The default address of the Micrel PHY chip is 0x00001 (see datasheet)
But you are using #define DP83848C_DEF_ADR 0x0100 /* Default PHY device address */
So I was wondering if this was the working code.
In that case, you had another PHY chip or the PHY address pins are different from the older olimex boards

It worked on my board. That address gets bit-wise ORd with the phy register
number, so perhaps that explains it. AIUI, 0x0100 would be phy 1 register
0. I did not write most of the code, and it's been a year since I played
with it. IIRC, there is ERRATA info on the 2378 with regards to the buffer
setup (number of descriptors).

To follow up, I did a "make clean" followed by "make" to rebuild it all. I
then tested it with my board and it works just like it should. I could ping
the board with no problems. That particular #define came from the sample
code I hacked up.

Michael,
Could you send me a copy as well?
Many thanks in advance.

Would you please send me a copy of your file too?
I am using the LPC2468-16 OEM Board from EA which has the Micrel PHY
KSZ8001L. I hope your code could ease my efforts to get it running.
Thank you.

Man, I sure didn't expect that much interest in some junk code. ;-)
Warning: This code is not even close to production quality, it's just some
stuff that I got to work at home. I didn't write most of it; it came from a
Keil example IIRC. It doesn't handle having the network cable plugged in
after initialization since it wants to negotiate with the hub during init.
