Hi, i have a Ti evaluation board (TMDSEVM437X). But i made a mistake. I modified EEPROM data by using I2C commands,eg "i2c mw 0x50 0.2 1 5". 0x50 is EEPROM chip address and 1 is data what need be writed. EEPROM contains specific identity and configuration information for that board. So the board can‘t run U-boot. I have no logs to print after the board start up. I read U-boot source code and discovery that the SPL (MLO file) need read EEPROM to detect board. I think the serial uart can't be used in SPL. What can i do it to solve the problem?
