T1042 CPU Board DPAA Development

[Oxygen]

Dear Community

I am currently working on developing a DPAA driver for the T1042RDB development board. I would like to enable Gigabit Ethernet speeds on the Ethernet interfaces available on the T1042 CPU. Could you please advise on the necessary steps to achieve Gigabit Ethernet functionality?  

Additionally, I have come across the NetComm software on NXP’s official website, which was described as a standalone driver. However, the page hosting this software appears to have been removed.  

Could you please guide me on how to access the NetComm software libraries or any available source code, in order to better understand its structure and functionality? 

Thank you for your support.

Best regards

Dear @Oxygen,
You need to configure the SERDER in order to select the correct protocol you want to use, then you can set the "auto-negotiation" in the device tree.
Unfortunately, NetComm is no longer supported and cannot be accessed.

Thank you for response,

We would like to use only one Ethernet port at gigabit speed on the T1040 CPU. Could you please assist us with the necessary steps to achieve this, particularly regarding SERDES configuration?

Dear @Oxygen,
you could set the Serdes as next:
SRDS_PRCTL_S1 - 0x69
if you want to have only one then you have to remove the whole nodes that you don't want to use in the device tree.
please review the field SGMII_SPEED into the register MDIO_SGMII_IF_MODE
