Bindu,

Can you please provide more info? Have you modified the application in SDK 1.1.0.4?

What do you mean by EEPROM Pages?

Hi,

2048 bytes of EEPROM is used for ethercat application.

We are using locations 32000, for our application to store few important datas(180 bytes)

EEPROM Pages : CAT24C256 has 512 pages each page of 64 bytes, so we are using page 500 (i.e location 32000)

Is these locations 32000 are used for ethercat application?

Which are the EEPROM Locations used for ethercat Application, Which locations can be used for our application?

Regards,

Bindu

Bindu,

ESI EEPROM is emulated using SPI Flash in SDK. You can find more details here - http://e2e.ti.com/support/embedded/tirtos/f/355/p/314782/1098823.aspx
