[SOLVED] EEPROM Page shifting issue - from 1 page to next page

[desgin]

Hi
I am using EFM32 microcontroller.
Connected my external EEPROM through I2C.
EEPROM total pages are 512 and each page contains 256 bytes.

I need to move from 1 page to other page but its getting stuck.
Can anyone please help me!

Thanks in advance
Its bit urgent, please help me

Hi,

"but its getting stuck"
What is getting stuck? How did you test it?

I guess you did the "move" with the use of some software.
If so, then this software is the most probale cause of the problem.
Thus it´s urgent to show us your code.

What type is the 'external EEPROM'?

Elementary EEPROM write action can't cross page boundaries. Does I2C_write_EEPROM() handle multiple page write? Probably not. In this case, it has to be partioned into multiple single page writes.
