Hi,

I wanted to ask if L44 and L45 (VM_I2C_SCK and VM_I2C_DAT) are pulled up to 3V3 on module or will it have to be done on carrier card to interface with external BMC. Thanks.

Regards,

The pins are not used as you can see marked as “SNN”.

Thanks for the reply. We are designing with JAXi in mind. With reference to table 15-4 in DG_v2.4, we find having external access to Voltage monitoring (INA3221) really beneficial and therefore I asked for hardware recommendation and questioned on whether the I2C lines after the MUX on L44 and L45 pulled up on SOM or not.

There is pull-up in module but the port should not be used.

Thanks for clarifying
