Hi Gerald, I want to clone earlier version BeagleBone (whilte), just get rid of P8, P9 to make smaller size. I download u-boot,img and kernel from http://elinux.org/Beagleboard:BeagleBone#Image_Files. So basically my board will be same as BeagleBone (whilte). Do I still need to write some codes to EEPROM? >From BeagleBone (whilte) schematic, EEPROM is to store MAC Address and Variables, does u-boot.img do this job to write codes to save MAC Address and Variables? Can you explain how it works? Thank you, pro.
