Hi, there is custom board with LS1046A (1.8GHz) with discrete ddr4 (32bit bus, 2100MT/s)

it could go through qcvs ddr validation tool for parameters fine tune.

it is updated ddr parameters in duplicated LS1046A_FRWY target configuration

initialization file and set use_safe_rcw true with modified RCW

the connection is not successful, I dnot find any error in the log.

please help to advise what is setting wrong caused the issue.

should it use LS1046A_FRWY or LS1046A_RDB?

You can use LS1046A_FRWY as a referance but you need to modify it according to your custom board.

On your board do you have some DIP SW settings for hard-coded RCW? If yes..can you set up them?

Can you please share application which you are debugging?

Thanks
