i'm trying to write eeprom via i2c interface but i could'nt.

 

i2c eeprom address is 0x50 and i use following u-boot commands.

 

=>i2c md 0x50 0x00 0x01 // firstly i read 0x0000 eeprom address 

0000: ff   .

=>i2c mw 0x50 0x00 0x41 0x01 // 0x41 is written to 0x0000 eeprom adress 

=>i2c md 0x50 0x00 0x01

0000: ff   .                               // but it's same not changing.

 

 

i miss something when i try to write eeprom ?
