TSE MAC with Vitesse VSC8601, Simple Socket Server Example Problem

Altera_Forum · ‎09-10-2009

Hi,

I am trying to get the Simple Socket Server Example running with a PHY that is not supported by standard driver. I added a profile with the alt_tse_add_profile() function. When I start the SSS-Example I get the following console output:

Can't read the MAC address from your board (this probably means

that your flash was erased). We will assign you a MAC address and

static network settings

I checked RX and TX clock of RGMII-interface with a scope and they are there. On the RXD line I measured some action when the rx-led blinks but I didn't see anything on the TXD line. I don't know if this is OK in init phase. Software stops after saying Auto-Negotiation passed. Could anybody give me some hints where the problem is, please.

Right. By default, the TSE driver doesn't actually configure the PHY's mode.

The PHY will come up in whatever default mode the board designer has chosen. I'm guessing you've hit a situation where either the board designer didn't configure the PHY default mode properly (or completely) or you want to use the PHY in a mode different than what was chosen.

The software driver doesn't support this, automatically.

Please refer to the user's guide (http://www.altera.com/literature/ug/ug_ethernet.pdf)...specifically the alt_tse_phy_add_profile(), as that's what you'll have to do for your PHY.

EDIT: Ok, I missed that you've added your own profile in my first read through your post. Are you attempting DHCP or static IP configuration? Do you see anything coming from the target with Wireshark? If not, then start tracing the driver software to double-check proper initialization/configuration and to see if traffic is being sent or received (to the MAC) successfully.

Hi,

I am also designing using TSE MAC with RGMII interface.

I have finished the FPGA/SoPC design and now moving to software.

Is it possible to use Simple Socket server for my system?

I have Broadcom's BCM5482 PHY chip. Tell me what changes I have to make in Simple socket server program to work for this system.

Thanks,

Mangesh.

Just compile the SSS for your system, it should be able to use the MAC out of the box.

I don't know that PHY chip. IIRC the driver automatically switches to 100Mbit/s mode if it doesn't know the PHY chip. Have a look at the driver source code to see how to add a new PHY chip reference to the driver so that it can handle it properly.
