WIZ830MJ udp problem

Hi there,

Fairly new with the products.

I am using a WIZ830MJ board with the W5300. I am porting a previous project that used a WIZ820IO, but the serial link isn’t fast enough to give me enough datarate.

I currently use a 8-bit address bus, and the board is used with a Nios II processor. I am not using the W5300 driver (although I tried with similar results).

My problem is that I can’t open a UDP socket, and can’t set DHAR, DIPR and DPORT registers (they read 0’s or other when verified).

Here’s my configuration. Please note, for every write, the register is read again to double-check it is written properly. So of course, registers like IDR0 will read different (read-only) and S0_CR1 (returns to a different value once set).

Thanks in advance for any help.
