HI,
We are designing a custom board based on AM5728 EVM. In our design we want to utilize the eathernet ports (eth2, eth3) from two mii interfaces available in PRUSS2 . We modified the device tree by taking reference from AM5721 IDK .

we not getting any interface by giving ifup eth2 or ifup eth3. Upon examining with dmesg | pru " unabe to get pruss handle" observed.
Please help in this.
