# I2C Eeprom
## example: DIVA family processor (AM335x) or BORA Lite processor (ZYNQ) implements ConfigID using I2C Eeprom when NOR SPI is not present (module boots from NAND or SD)
## DIVA and BORA Lite use the first 32bytes on I2C EPROM to store ConfigID (and its CRC32), UniqueID (and its CRC32)
# 1-wire
## example: latest XELKAXEL Lite, DIVELK, BELK Carrier Boards AXEL ULite and BORA/BORA Xpress/BORA Lite Evaluation Kits implement CB ConfigID using the onboard 1-wire device (DS2431)
