+Subject: [PATCH 1/3] configs: am62x_evm_r5_ethboot: Fix syscon-related build
+ error
+
+The Ethernet boot defconfig needs the syscon driver to be enabled
+otherwise this will result in a build error as the Ethernet driver
+tries to read the MAC address from the efuses.

Thank you, we will check internally

Hi paula,

Could you please let me know if I can expect any update today?

Regards,vikash

Hello Murali,

The subject owner is going to be out of town for the next two weeks. I am reassigning your thread to another team member in the meantime to see if they can be of assistance.

Regards,

Nick

Hi,

Could you please provide the exact SDK version? Could you please provide the full log of the u-boot sequence? This has been tested in the SDK that is to be released in the next two weeks. If we know the exact commit id you are building from we might be to point to a patch. 

Best Regards,

Schuyler

Hi Murali,

Does the solution provided in https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1439307/sk-am62-lp-bootp---u-boot-console/ help? It looks like the same/similar issue was observed in this E2E thread.
