    You no need to do it manually, It will be handled by UDMA driver itself when open channel is invoked.
    If you already used the UDMA channel which you are trying to open via Eth init.
    Please make sure that the channel requested by Eth Init is available. If you are forcing to use specific UDMA channel from any other application other than Eth.

    SCI Client call fail will be one of indication that channel is not free.

    Can you please confirm have you integrated other applications along with MCAL Eth? If so, can you change the start position of UDMA channels in Eth configurator and check once.
