PROCESSOR-SDK-J721E: Adding DSA and 88E6XXX support to the Linux kernel

Part Number: PROCESSOR-SDK-J721E

Hi,

Our custom J721E design has an 88E6320 network switch connected to the MCU_RGMII_1 port.  

Can you provide the changes needed to tisdk_j7-evm_defconfig to add support for this device?.

I have seen elsewhere on this forum that make menuconfig is not supported and you need to edit tisdk_j7-evm_defconfig directly.  True?

I assume that changes are also required to the DTB?.

thanks

    You can use menuconfig as well from linux kernel to modify the config file. Run "make ARCH=arm64 menuconfig".

    As the device mentioned is the marvell device, we won't be able to provide you with the changes required for configuring the DSA with the switch. I request you to ask the switch manufacturer for the same. If you face any issues with further integration, feel free to raise another ticket.
