PROCESSOR-SDK-AM335X: AM335x to KSZ9893 / KSZ9563

PROCESSOR-SDK-AM57X: CPSW Driver custom work

Part Number: PROCESSOR-SDK-AM57X
Other Parts Discussed in Thread: AM5718

SDK : ti-processor-sdk-linux-rt-am57xx-evm-05.03.00.07

KL : linux-rt-4.14.79

Hello.

I am working for the interface between cpsw and dsa of am5718 custom board.

The chip connected by cpsw and mac-mac is ksz9563.

We know that this technical support is not within the scope of TI.

However, we analyzed it for three weeks to solve this problem, but we couldn't find the answer. (I'm a rudimentary embedded developer.)

The KSZ9563 driver specifies the Ethernet node associated with the CPU, but cpsw_emac1 is not recognized and only Mac is recognized.

It also appears that the driver communicates only with RGMII0 (Slave LAN1, LAN2 pulses follow ETH0).

I modified the KSZ9563 driver for the kernel version, but I don't know how DTB recognizes the CPU port.

The CPSW driver looks for parts where SLAP [0] is the main part, but changes to SLAP [1] result in an error.

Please let me know the guide for mac-mac customization.

I really want to succeed. I beg you.

    Hi,

    Re-opening this thread after some time. Apologies.

    Is this issue still open ?
