Hi,

I'm using imx8qmmek board. i'm working on i2c eeprom.. i am able to write and read 256 bytes to eeprom i'm trying to write more-than 256 bytes not able to write. For above 256 bytes write and read any user space application required?

Hi KUMAR

reason may be is that page size is 256 bytes, so it is necessary to set individual page

for write procedure.

Best regards
