C6657 MAC address change.

dmitriy

Hi. I want to change MAC address in Client demo program. I tried to change it via registers:

volatile UINT32 *MACID_1 = (UINT32 *) 0x02620110;
    volatile UINT32 *MACID_2 = (UINT32 *) 0x02620114;
   /* To Unlock */
    (*(unsigned int*)(0x02620000 + 0x0038)) = (0x83E70B13);
    (*(unsigned int*)(0x02620000 + 0x003C)) = (0x95A4F1E0);

    *MACID_1 = 0xCCDDEEFF;
    *MACID_2 = 0x0000AABB;
    platform_get_emac_info(0, &emac);

But it didn't change.

I want in my project use the IP Stack from Client project, but i need to change MAC address.

How can i do that?

Thanks.

Hi,
I hope you are using NDK for developing your application . Please refer NDK user guide to set the MAC address.

Refer, NIMUIoctl - Get/Set configuration from the NIMU Module and Drivers.

Thank you.

Please refer below post for insight,

Basically, the NIMU driver under C:\ti\pdk_C6678_1_1_2_6\packages\ti\transport\ndk\nimu\src\nimu_eth.c, the function EMACInit_Core, there is a call to platform_get_emac_info followed by memcpy(ptr_pvt_data->pdi.bMacAddr, emac_info.mac_address);. You can try changing emac_info.mac_address to a custom address of your choice, or change the platform function to fit your requirements. Remember to recompile both the library and your application using this library.

Thank you.

I try NIMUIoctl with NIMU_SET_DEVICE_MAC command and it returns -1; command NIMU_GET_DEVICE_MAC returns correct MAC address.
