You’d have to have more than one, sure. You might be able to ping-pong between 2 – but without copying you stand to lose packets if you don’t finish with the first and the second one has come in and then a third is pending.Billi suppose i could have a driver with more than one pbuf allocated... it could be more efficient... but, my problem, is the pbuf allocation memory:DMA MUST works in FIXED region in memory, and instead i have no control where pbuf payload are allocated... do you have a solution?
