In EEPROM memory is stored configuration words. And configuration word is strored properly because after unplug BDI board starts fine and we can reading memory via OS. I tryied to change SPEED too.
On 83xx boards, CFG_I2C_SPEED is not used. This is a known bug that I intend to fix one
day. The actual speed value that is programmed into the controller is hard-coded and is
somewhat conservative. See function i2c_init().
