Hi Ashwani

We are using SDK7.

Can we just configure register to achieve this? Is it tightly bounded to which version of SDK?

Hi Zekun,

Thanks for reply.

Assuming you are working on PROCESSOR-SDK-LINUX-AM437X Software development kit (SDK) | TI.com

I have assigned your query to PDK expert.

Please refer to the following E2E FAQ for guidance for RTOS development on AM437x.

Hello Zekun,

Are you using Linux or TI-RTOS (SYS/BIOS)?

Thanks,

Hi,

There is not an option to program e-fuses on the AM437x class devices for MAC addresses. Typically this is done using an external storage device such as a I2C EEPROM. Based on your question to me this means this would not be an option, is that correct?

Best Regards,

Schuyler
