SMARC-iMX8M Computer on Module User’s Manual v.1.0
2.1.21 Boot ID EEPROM
The
SMARC‐iMX8M
module includes an I2C serial
EEPROM
available on the
I2C_GP
bus. An On Semiconductor
24C32
or equivalent EEPROM is used in
the module. The device operates at 1.8V. The Module serial EEPROM is
placed at I2C slave addresses A2 A1 A0 set to 0 (I2C slave address 50 hex, 7
bit address format or A0 / A1 hex, 8 bit format) (for I2C EEPROMs, address
bits A6 A5 A4 A3 are set to binary 0101 convention).
The module serial EEPROM is intended to retain module parameter
information, including serial number. The module serial EEPROM data
structure conforms to the PICMG® EEEP Embedded EEPROM Specification.
Note:
The
EEPROM ID
memory layout is now follow the mainline and as follows.
