Hi limshutian,

Do check your pin mapping once,as I faced a issue in my write when there was pin mapping problem.

Are you able to access DDR4 from HPS now? In HPS i have a 128 bit data whereas my DDR4 is 512 bit. When I send 4 data from HPS, the data must be combined and stored in DDR4. When I read back from HPS, I have to get all 4 data. But I get only the last data.

Did you face this issue or how did you try writing data?
