AM3358: DDR CASn & RASn Interchange issue

Pavan Patil

Part Number: AM3358

Hi,

We have a design with AM3358 and ISSI DDR3. We have a design issue on the hardware/schematic. The connections for CASn and RASn are interchanged i.e RASn of AM3358 is connected to CASn pin of the DDR and vice-versa.

We wanted to know if any software changes can be done to accomodate the same design. We are using yocto v3.1.

Any help on this is much appreciated.

Thanks & Regards,

Hi Pavan,

not sure if this is possible, I've looped in our DDR expert to comment. Stay tuned.

Seems this is a repeat question: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1233723/am3358-unable-to-boot-the-custom-board/4673696#4673696

There is no way to swap these internally.
