3.2.2 EEPROM configuration
Table 3 shows all the useful information about the board stored in the EEPROM. The default manufacturing settings are indicated
in the "Data" column. The EEPROM configuration settings can be updated using the BCU or PMT tools, e.g. to set a new
board-specific serial number value (BOARD_SN).

Comments
BOARD_ID 0x1A
NXP i.MX8MP EVK
PWR Board
These two information are very important.
Ensure that they are set properly in the PMT YAML
configuration file.
In the BCU, provide the correct [-brev=] value in the
command if you do not use the default revision value.
Note: A1 is the latest board release to be adapted to your
board version.
BOARD_REV 0x1C A1
SOC_ID 0x1D i.MX8MP
This is related to the [-board=] option and it cannot be
changed manually in the BCU.
SOC_REV 0x1E A1
In the BCU, provide the correct [-srev=] value in the
command if you do not use the default revision value.
Note: A1 is the latest SoC revision to be adapted to your
SoC board revision.
PMIC_ID 0x1F PCA9450CHN
These are related to the [-board=] option and they cannot
be changed manually in the BCU.
PMIC_REV 0x20 N/A
NBR_PWR_RAILS 0x21 27
BOARD_SN 0x22 1
Board-specific serial number, user-defined
(range: 1~65535).
