Thank you for your reply.
Usually, one Frame Buffer is used for reading & writing operations. However, I want to separate the reading apart from the writing using 2 different Frame Buffers because there is some processing required after the writing and before the reading (Ethernet TX&RX). This is shown in the attached brief block diagram.
1- Please confirm that: this block diagram is suitable for testing purposes.
2- If it is suitable, how can we choose the SDRAM address for reading and writing operations done by the Frame Buffer and SGDMA?
