TCI6486 EVM EMAC0 problem

sungyi chen

To whom might concern,

We tried to configure TCI6486 EMAC0 but it was not working as EMAC1 as well on TCI6486 EVM board. Does anyone can help me?

1. EVM console setting

l enet reset

l enet config dual

2. CSL6486 EMAC example

EMAC_load()

l ecfg.ModeFlags = EMAC_CONFIG_MODEFLG_FULLDUPLEX | EMAC_CONFIG_MODEFLG_GMIIEN;

l or (ecfg.ModeFlags = EMAC_CONFIG_MODEFLG_FULLDUPLEX | EMAC_CONFIG_MODEFLG_RGMIIEN);

l ecfg.MdioModeFlags = MDIO_MODEFLG_FD100;

l EMAC_open( 1, (Handle)0x12345678, 0, &ecfg, &hEMAC );

enableEMAC()

CSL_PscPeripherals module = CSL_PSC_MODULE_EMAC0;

3. DSP/BIOS(*.tcf)

l HWI9 for EMAC0 RX with event 5

l HWI10 for EMAC0 TX with event 6

We could configure EMAC1 and EMAC1 was working successfully. We can get the broadcast EMAC package and sent the EMAC packet out.

Could anyone know how to fix the problem

Sungyi,

Refer to the TCI6486 User Guide. You are using 'enet config dual'. This makes both Ethernet connectors active. One connects through a Gig switch to EMAC0 and one connects through a 10/100 switch to EMAC1. If you want to only have one Ethernet connection, use 'enet config single'.

Tom,

I did it before but EMAC0 did not work. I guess I might need to configure EMAC0 PHY but I can not find how it works.

I tried u-boot command "ges" but it did not work.

Sungyi,

You are mixing message threads. My response above is sufficient for the question in this thread. There is no need for 'ges' UBOOT commands to receive or send packets to the network.
