Tool/software:

Hi,

There are 2 options for assigning MAC addresses in the ENET CPSW driver in sysconfig.

Auto -- (EFuses) or Manual (List). Unfortunately, neither of these fit our requirements.

I want to change the MAC address at runtime -- it will be read from Flash by the main application, before

Please advise on the best method to do this.

Hi Toby Grabham,

I suggest to enable custom board option, and enable the necessary changes for the custom board, so that you can remove this dependency from the code. You can find the documentation to enable the custom board can be found here: https://software-dl.ti.com/mcu-plus-sdk/esd/AM64X/latest/exports/docs/api_guide_am64x/enet_migration_guide_top.html#CustomBoardSupport

Then, you can implement the read function for MAC addresses in the function "EnetBoard_getMacAddrList" in your custom board_config.c to read MAC addresses from Flash memory. Please reach out to us if you need any further assistance on this.

Thanks and regards,
Teja.
