Hi Ajay Bharti,
About the EEPROM code of K 20 50Mhz, actually, in our www.freescale.com, there has a flash driver which include this code, please download the driver from this link:
http://cache.freescale.com/files/32bit/software/C90TFS_FLASH_DRIVER.exe?fromsite=zh-Hans&Parent_node...
After the soft setup in default, you will find the code in the path:C:\Program Files\Freescale\Standard Software Driver vBeta035\C90TFS\Demos\build
This code is base on the APIs function, and in the soft setup root directory, there has a document named of UM_C90TFS_FTFx_SSD.pdf, it describes the function in details.
I wish my answer will help you!
If you still have question, please contact with me!
Best regards!
