TSE MAC and Marvell 88E1111

Hey guy,

I have successfully make it works before(same dev board, same on-board PHY). A few tricks:

1. You need to do a RESET on the onboard Marvel PHY when you power up the board (only for this particular onboard PHY, I have no such problem with other Marvel88E111 daughter card or SFP). It is described in the Marvel document as about 10ns second reset (if not mistaken). You can either tie the PHY reset pin to the on board reset button or just use some hard logic to do it. Very odd, powerdown/powerup the board doesn't cleanly reset the PHY.

(2. to 4. only apply if you are not using the sample application/example design/default TSE driver)

2. You need to make sure that your MAC, ethermode/speed bit in the command config register represent the mode the PHY is currently working at

3. Remember to turn off the INTERNAL_LOOPBACK register bits:)

4. Make sure that you know you are using/not using the 16-bits byte shifting/alignment feature (synthesis/register option in TX/RX_CMD_STAT),

I don't think you need a Marvel Datasheet, all the general settings of any PHY is described in the TSE documentation, unless you need some extended/proprietary settings like turn on the automatic clock adjustment for RGMII interface.

Thanks.

I somehow got it to work after playing with it for a while. I added some "redundant" initialization sequence in the logic including a reset of the PHY after power up. I suspect that's what made it work as you pointed out.

Hi,

I've got a pci express demo board and i want to use GbEthernet communication.

For now, I was able to instantiate TSE MAC and make logic for initialization. with a big sate machine just like in the provided altera test bench. That seem's to work.

But when i send frame on tx fifo interface, nothing come back on the rx fifo interface. And loopback is activate... I think some initializations are missing. I put below my init sequence. could you help me and say me if I wrong or not ?

Init TSE MAC Sequence:

- Read Version (@0x00) and check 0x00000800

- Write Scratch (@0x01) to 0xAAAAAAAA, readback and check

- Write Config (@0x02) to 0x040083EB

TX_ENA & RX_ENA = 1

ETH_SPEED = 1

PAD_EN = 1

CRC_FWD & PAUSE_FWD = 1

PAUSE_IGNORE = 1

TX_ADDR_INS = 1

LOOP_ENA = 1

RX_ERR_DISC = 1

- Write mac_0 & mac_1 (@0x03 & 0x04) to 0x22334450 & 0x0000EE11 (choose MAC: EE1122334450)

- Write ipg length (@0x17) to 0x0C

- Write frame length (@0x05) to 1518 (0x5EE)

- Write pause quanta (@0x06) to 0x0F

- Write rx_section_empty (@0x07) to 0x00

- Write rx_section_full, tx_section_empty, tx_section_empty (@0x08, 0x09, 0x0A) to 0x10

- Write rx_almost_empty, rx_almost_full, tx_almost_empty (@0x0B, 0x0C, 0x0D) to 0x08

- Write tx_almost_full (@0x0E) to 0x0A

- Finally, Write mdio_addr0 (@0x0F) to 0x12.

(Sorry for all this details but I wan't you have all the informations to help me!)

Did I forget something during init process ?

Could you help me ?

Thanks you very much!

Fabrice.

Hi,

I am using Stratix II gx board and TSE MAC core. Can u please give some more details (logic )on reset logic required to use MARVELL PHY.

Thanks

Marvel Data sheet ?

Where did you find that, I have been googling around all over and all I find is the 2 page Product brief.

Any help greatly appreciated!

Marvell does not release their datasheets over the web except to users who have a login.

Did you find how to do the hardware reset? I am looking for the same information

Find in attached file a screenshot of the original marvell 88e1111 datasheet for its hardware reset sequence.

Works fine on my pcie express board.
