You also need a simple way of incrementing the pointer and wrapping back to the start if necessary. Note that if you want to wait for an interrupt you will also need to set bit 6 of CSR0 or interrupts won’t be generated you will need to enable this anyway to get notification of received packets, so it makes sense to set it at the same time as the initialization bit. LADR is the logical address filter you want the card to use when deciding to accept Ethernet packets with logical addressing. About This site Joining Editing help Recent changes. There are two ways of setting up the card registers: Depending on your design this may be preferable.

If you want to keep the current one, you will need to first read it from the EPROM of the card it is exposed as the first 6 bytes of the IO space that the registers are in.

In other languages Deutsch. See the spec description of CSR15 for further details.

During normal initialization and use of the cards, the CSRs are used exclusively. The card uses two ring buffers to store packets: Enter the e-mail address of the recipient Add your own personal message: Given that the MMIO access is sometimes absent on emulators or certain systems, this article will focus on the IO port access. And you may want to set bit 11 of CSR4 which automatically pads Ethernet packets which are too short to be at least 64 bytes.

Interrupt done mask – pic set then you won’t get an interrupt when the card has finished initializing. This page was last modified on 11 Juneat Once reported, our staff will be notified and the pdi will be reviewed.

Views Read View source View history. There are two ways of setting up the card registers: You are logged in as. Thank You for Submitting a Reply,! The card regularly scans all the transmit buffers looking for one it hasn’t sent, and then will transmit those it finds. You also need a simple way of incrementing the pointer and wrapping back to the start if necessary.

If you do not wish to use logical addressing the defaultthen set pcner bytes to zero. MODE provides various functions to control how the card works with regards to sending and receiving packets, and running loopback tests.

Flaming or offending other users. Contents 1 Overview 2 Initialization and Register Access 2.

You need to parse ACPI tables etc. At initialization, you would want the card to ‘own’ all the receive buffers so it can write new packets into them that it receives, then flip ownership to the driverand the driver to ‘own’ all the transmit buffers so it can write packets to be transmitted, then flip ownership to the driver.

You should also have a variable that stores the current ‘pointer’ into each buffer i. The card maintains separate pointers etgernet. Receiving packets is normally done in your interrupt handler – the card will signal an interrupt whenever it receives a packet and has written it to the receive buffer.

You can do this by either waiting for an interrupt if you didn’t disable the initialization done interrupt in CSR3 or by polling until CSR0 bit 8 is set.

Promote cracked software, or other illegal content. Advertisements or commercial links. Note that interrupts can come from many sources other than new packets. Your message has been reported and will be reviewed by our staff.

You will need to allocate a 28 byte region of physical memory, aligned on a bit boundary. In this article we will use the latter.
