Re: olimex LPC-E2294 with ethernet

2005-02-08 by Gus

I got it to work last night. The problem is that olimex board has 
the chip connected to 16-bit data bus but it will NOT work. It works 
in 8-bit mode only.

What are the negative things about uIP? I used telnet and http last 
night and it worked fine!
