You probably want to set it to zero enable transmit and receive functionality, receive broadcast packets and those sent this physical address, disable promiscuous mode. 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. You should also have a variable that stores the current ‘pointer’ into each buffer i. Advertisements or commercial links. There are two ways of setting up the card registers:

We will flesh out the interrupt handler later, but you should install the interrupt handler here as otherwise you will get pcnnet due to unhandled interrupts. About This site Joining Editing help Recent changes. 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.
This article will focus on the Am79CA a. This page has been accessed 13, times. Once initialization has completed, you can finally start the card. If a new packet has been signalled then CSR0 bit 10 will be set. Flaming or offending other users. Pcne done mask – if set then you won’t get an interrupt when the card has pnet initializing.
In this article we will use the latter. There are two ways of setting up the card registers: Sexually explicit or offensive language.

You also need a simple way of incrementing the pointer and wrapping back to the start if necessary. This means that the index of the register you wish to access is first written to an index port, followed by either writing a new value to or reading the old value from a data register.

Advertisements or commercial links. If you do not wish to use logical addressing the defaultthen set these bytes to zero. It has built-in support for CRC checks and can ethrnet pad short packets to the minimum Ethernet length. Depending on your design this may be preferable.

Given that the MMIO access is sometimes absent on emulators or certain systems, this article will focus on the IO port access. 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 are logged in as. There are other bits in CSR0 than can be set depending on how you set up interrupt cpnet in CSR3 and additionally other bits in CSR4 that can signal interrupts although these are usually masked out on reset.

Personal tools Log in. You will need to allocate a 28 byte region of physical memory, aligned on a bit boundary. Select type of offense: The card maintains separate pointers internally.
A further important register exists in the IO space called the reset register.
