AM6442: MAC address allocation for dual MAC mode

Sung-IL

Part Number: AM6442

Dear Champs,

My customer found there is only 1 MAC address stored in CTRLMMR_MAC_ID0/1 registers, and is curious if they can use internal MAC addresses for dual-MAC mode.

To use dual-MAC mode, customer should allocate their own MAC addresses for dual-MAC mode?

Thanks and Best Regards,

SI.

Hi Sung-IL,

Thanks for your query.

Can you please elaborate a bit more what exactly you are trying to achieve ?

What I got : you are working on ICSSG with DUAL MAC MODE ?

Which SDK you are working on ?

Which example you are referring here ?

Best Regards

Ashwani

Hi Ashwani,

They are working on CPSW with dual mac mode. I'm questioning about CPSW.

They are using MCU+SDK v8.6.0 on AM64x.

I'm not sure if this is related with SW. My question is if there are internal registers having MAC address when device released to customer.

Thanks and Best Regards,

SI.

Hi,

There is one MAC address stored in the part that is a TI MAC address. The i2c eeprom usually has others to cover both the CPSW and the PRU Eth ports.
