Please ensure that FMC+ Connector-2 power is enabled. By default, FMC+ Connector power is disabled and “vadj-millivolt” voltage compatibility is checked while booting by reading the FMC+ Module’s EEPROM to enable corresponding FMC+ connector power.
If the FMC+ module’s EEPROM is not programmed or uses a different I2C slave address, the FMC+ connector power can be enabled by executing the following commands in U-Boot.
FMC+ Connector-2 – Power on:
To set fmcp2-vcc-12v GPIO, execute the below command
IG43M # gpio set gpio@20_4 gpio: pin gpio@20_4 (gpio 52) value is 1
To set fmcp2-vcc-3v3 GPIO, execute the below command
IG43M # gpio set gpio@20_7 gpio: pin gpio@20_7 (gpio 55) value is 1
To set fmcp2-vcc-adj GPIO, execute the below command
IG43M # gpio set gpio@20_1 gpio: pin gpio@20_1 (gpio 49) value is 1
Please refer to section “FMC+ Connector Power on” from the Software User Manual for instructions on enabling power to the other FMC+ connectors.
