Hi,

 

We have some problems with ethernet peripheral on LPC546. When we send lot of packets (approx. at 1MBits/s) , we drop lot of packet and the OVFPKTCNT register is fill. I try to configure the "multi queue" offer by the SDK but it doesn't work... Someone have an example? Or any idea for this problem?

 

We haven't this problem with an LPC17, where is the difference?

 

 

I used Freertos+LwIP, with none buffer full.

 

Thanks for your reply

Regards
