Hi,

Does MPC5748G D-cache only support writethrough? or writeback is also supported?

If it supports both, how to configure it?

Thanks.

It only supports Write-through mode. Writeback (we called it Copy-back) mode has been removed, as I know, from all MPC57xx devices excluding MPC5777C, probably due to low utilization.

Copy-back mode exists on MPC55xx and MPC56xx legacy devices.
