Updating PHY Firmware#
MVQ3244 PHY Firmware Update (Thor)#
Starting in 7.0.3.0, you can manually upgrade or downgrade PHY firmware directly from Tegra.
Understanding MDIO Switching#
On the P3960 platform, all MVQ3244 PHYs are updated using the MDIO interface of the MGBE0 Ethernet controller.
Normally, downstream PHYs are controlled by the sMCU’s MDIO. For OTA updates, control must switch to MGBE0 MDIO.
Before running OTA commands on downstream PHYs, execute:
setphymdiomuxsel 1
To check current MUX selection:
getphymdiomuxsel
0 means controlled by sMCU.
1 means controlled by Tegra.
Note
MDIO of the PHY directly connected to MGBE0 cannot be switched to sMCU control.

Updating PHYs Directly Connected to Tegra#
Firmware binaries and OTA scripts are located in:
/lib/firmware/marvell_ethernet/mvq3244/tools/fw
Example update command for Condor 1, Port 10 on TS2:
// Updating MVQ3244 connected to P3960 - Condor-1 P10 on TS2. In the script used below _0x06 represent SMI address of the PHY
sudo /bin/bash /lib/firmware/marvell_ethernet/driveota/P3960_MVQ3244_TS2_0x06.sh --Install <FW>
Check current flashed firmware:
// Printing current firmware version of MVQ3244 connected to P3960 - Condor-1 P10 on TS2. In the script used below _0x06 represent SMI address of the PHY
sudo /bin/bash /lib/firmware/marvell_ethernet/driveota/P3960_MVQ3244_TS2_0x06.sh --GetCurrentVersion

Important Notes#
Note
Newly installed firmware takes effect only after sMCU power cycle.
NVIDIA recommends against manual PHY firmware updates unless necessary or instructed by NVIDIA.
Always use the script intended for the specific board and platform.
