Issue Details:
The investigation revealed that the issue did not originate from the multi-core image boot,
Rather from a failure to initialise the PHY during the TCP server startup.
The example used is enet_cpsw_tcpserver_am273x-evm_r5fss0-0_freertos_ti-arm-clang.

From the UART logs, at power-on and when the reset button was pressed:
On the first boot - Example fails
After board reset - It works

SDK version - 09.02.00.52
Evaluation board - TMDS273EVM
Example used - C:\ti\mcu_plus_sdk_am273x_09_02_00_52\examples\networking\lwip\enet_cpsw_tcpserver is imported into CCS and built. The application runs solely on CPU0.
The issue still occurs even when running solely on CPU0.
