Go to the documentation of this file. Set an event object to the signaled state from an interrupt service routine. Initialize DMA descriptor lists. Enhanced RX DMA descriptor. Read data from a multi-part buffer. Structure describing a buffer that spans multiple chunks. Configure MAC . Kernel – Network device driver programming Objective: Develop a network device driver for the AT91SAM CPU from scratch. AT91SAM datasheet, chapter 41, about the EMAC Ethernet controller. More specifically, the part , describing all the registers, will be particularly useful in .

Ethernet Media Access Controller (EMAC)/ Literature Number: SPRUHH1 July Management Data Input/Output (MDIO) User Guide. ø-ii KeyStone Architecture EMAC/MDIO. The required functions for implementation of the driver are: init_ethernet() - initializes the ethernet controller poll_ethernet() - reads the packet out of the ethernet controller's buffer send_frame() - writes a packet to the ethernet controller. You can also use the Ethernet interface in interrupt mode. The network stack using an EMAC driver provides it with a reference to the memory manager in use before powering up - this is constant as long as the EMAC is powered. Memory buffer chains store the data on the memory interface.
