Hello, @piaochunri

Thanks for you post.

May I know if you are working with the BSP35, would you please share the hwconfig and the pfe_xxx related uboot environments used?

Hello, @piaochunri

Thanks for your post

According to serdes working modes in the S32G3RM Rev4, and your specific requirement, seems only mode1 for both serdes0 and serdes1 could fulfill your request.

However, since your were using the BSP39, as indicated below from BSP39 UM

Mode1 on Serdes0 is not supported.
