AM2612: AM2612 Ethernet setting

Kita Li

Part Number: AM2612

Hi experts,

My customer is using AM2612 Ethernet.

If customer wants to individually control whether forwarding is enabled for a specific port, using:

CpswAle_SetPortStateInArgs inArgs; int32_t status; inArgs.portNum = alePortNum; inArgs.portState = state; ENET_IOCTL_SET_IN_ARGS(&prms, &inArgs); status = ENET_IOCTL(hEnet, coreId, CPSW_ALE_IOCTL_SET_PORT_STATE, &prms);

Would setting the state to CPSW_ALE_PORTSTATE_BLOCK work?

Best Regards

Hi Kita,

You are right, this IOCTL will block the forwarding if used with BLOCK parameter.

Hi Shaunak,

thanks for your confirmation. Customer would also like to know, during testing, is there a corresponding register to confirm this? Is it the CPSW_NC_ALE_I0_PORTCTL0_J register? This register can only show the settings for MAC1, correct?

Thanks!

Best Regards

Kita

Hi Kita,

I believe the default address if for port-0 (0x)

If you want to access the Port Control register for Port 2 or Port 1, you apply the index into the formula:

As per the Register addendum i see we have an option to check for different ports

Same can be seen in cslr_cpsw_nc_ale.h file in SDK
