Power Measurement on i.MX 8MM EVB Kit

[JK_Cha]

Hi i.MX champ

Can you please let us know how to set up the power measurement on i.MX 8MM EVB Kit?

Please indicate where to add 0.025 series resistor on EVB Kit.

Thanks.

Hi @JK_Cha,

If one wants to measure power for the VDD_ARM_0V9 power rail, one needs to remove the R141 0R resistor and populate the 0.025R (with a tolerance of 1% or less) resistor. The power value is obtained by measuring the average voltage drop over the measurement points and dividing it by the resistor value to determine the average current.

Thanks & Regards,
