We want to use double buffer mode for IDMA CH23 and CH27 channels in i.MX6 S. We are selecting the double buffer mode by setting ch23 and ch27 corresponding bits in IPU_CH_DB_MODE_SEL0 register.


But only EBA1 memory data  only appearing on LCD and EBA0 memory data is not  appearing on LCD


Could you please suggest anyone, is any other settings are required for enabling the double buffer mode.






Thanks & Regards
