Inquiry on Hardware Changes and Driver Support for RZG3S custom board

Question

Dear Renesas Support Team, 
 
 I hope this message finds you well. We are currently working with the Renesas RZG3S and making some hardware modifications. Specifically, we are looking to implement the following changes: 
 
 Memory Change: Replace the existing LPDDR RAM with DDR4 RAM, specifically the MT40A256M16LY-062E. 
 Battery Management Integration: Incorporate the RAA241200 Single Cell Li-ion Battery Management IC. 
 
 We would like to confirm if these changes are feasible from a hardware perspective. Additionally, we are currently unable to locate the necessary Linux drivers or patches for these components. If these changes are indeed possible, we would greatly appreciate your assistance in providing the required drivers or any relevant patches.

Hi Nitish, For the DDR memory you should follow the PCB design guideline DDR4 . You will find also a tool which helps you generate your DDR parameters to a file. For the RAA241200, I suppose you will use the I2C interface to interact with the RZG3S and/or UART. Please post your query on Power products forum for driver support. Kind Regards.
