Hi @vishnu.k

No, ECC pins cannot be swapped with other bytes lanes as ECC bytes are dedicated.
Please see the snippet below from UG1085: (https://www.xilinx.com/support/documentation/user_guides/ug1085-zynq-ultrascale-trm.pdf

Please note, it is allowed to do bit swapping within the ECC byte lane.
