If bit swapping is required during custom board design, bit swaps within a data byte, and swapping of byte 0 / 1 are allowed, with some restrictions. Do not swap the DM and DQS bits with any other signals. Bit swapping of the address or control bits is not allowed.
For more information, see the Bit Swapping section in the DDR4 Board Design and Layout Guidance chapter of the AM62x DDR Board Design and Layout Guidelines.
Update the schematics with the bit swapping changes for future reference or reuse.
