AWR2944: Query on PHY ADDRESS to be used for Marvel Transceiver on AWR2944x

Eswara Chaitanya Sreemanthula

Part Number: AWR2944

Hello Team,

We are trying to read the Marvel Transceiver Registers using below APIs

We had used the API CSL_MDIO_phyRegRead of TI SDK to read the Transceiver. However we are not getting the right data

Please find the Arguments passed

CSL_MDIO_phyRegRead(0x07000F00uL,0x8000, 2,&Regvaluptr)

0x07000F00uL = MDIO Address

0x8000 - SGMII Control Register Address of Marvel Transceiver

MCU - TPR12, AWR2944x

Thanks

Hi Chaitanya,

The parameters should be:

MDIO base Address, Phy address, Phy register address, &data.

Can you please confirm API usage correctly? Why is 0x8000 being sent as Phy address?

Regards,

Ajay

Hello Ajay

From Marvel Transceiver Document i could see the PHY starting ADDRESS as 0x8000.

Hello Ajay

Can you Please confirm if the above API Can be used to acheive the Functionality ?

Hi Chaitanya,

Phy address will be 0 to 31.

This will be generated in syscfg "ti_board_config.c"

If you have only 1 Phy connected. it is most likely that this is 0.
