[lwip-users] DM9000 in polled mode

[Nishen Naidu]

Hi,

 

I am trying to use the DM9000 in polled mode as opposed to the interrupt manner.

It seems to ping fine for a while and then about after every 20 successful pings

there seems to be an error receiving a packet(when reading the 0xf0 register - it

suppose to return a 1 or a 0 indicating whether a packet is ready or not. 

Instead it returns another value which the code says must reset the card. ).

If the card is not reset, then there is no notification of a received packet from that

point on.

Any idea what might be going wrong?

 

Thanks
