I’m implementing a zero copy driver for the SAMEXX. I have a question about the SendData function. I understand that it activates the transmit, but should it also only return after a completion of the TX. The next lines in the xATSAM5x_NetworkInterfaceOutput function releases the network buffers, but should it do this only after a successful TX.
I’m using V4.0.0. Is the Network interface driver for “DriverSAM” a better example to follow for zerocopy?
Thanks
