EVMK2X: Can ARM and DSP use different ethernet port at the same time?

Hi Tony,

The Ethernet function is enbaled using the device tree source(DTS) in Linux. Please refer the linux-keystone/arch/arm/boot/dts/k2hk-net.dtsi file for ethernet interface specific initialization.

Thank you.

Hi, Tony,

You should be able to.  you can try using the example, PA_emacExample_K2HC66BiosExampleProject, in PDK to configure DSP for different ethernet port. All ethernet ports are connected to the switch in 66AK2H14. The incoming packets are switched to its destination.

Hi Rex,

Thanks for your information.

You said "configure DSP for different ethernet port." Do you mean to change the below setting? or others?

paEthInfo_t                 ethInfo     =  { { 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 },        /* Src mac = dont care */  
                                                 { 0x10, 0x11, 0x12, 0x13, 0x14, 0x15 },        /* Dest mac */

Tony,

No, not to configure the mac address, but the sgmii initialization, Init_SGMII(). The example code only configures eth0 (PortNum 1) using PHY and run test against it. You need to use the same configuration for eth1.

Hi Rex,

Thanks for your reply.

One more question, does configures eth1 means usgin PortNum 2 ?
