The ST ENET software don't handle RX overflow, anyone know about to add function to handle it.

I found example in driver from Keil about if no descriptor is availble

the DMA fetch stop and have to be started again, I add this to my software, but it still stop. Any idea what more have to be added

Hi

I can't answer the question because I have never observed an RX overflow but it would be interesting to know how many rx buffers you use.

Presently I have an STR912 on line at

and have never experienced a problem with it (4 rx buffers). Are you also testing with very high traffic levels?
