Hi all

 

 

My customer will start a development for first prototype and want to confirm about requirement of operating range with i.MX6SL.

 

Does user must to satisfy a following requirement ?

(The requirement is described in IMX6SLCEC)

 

「VDD_ARM_IN and VDD_SOC_IN must be at least 125 mV higher than the LDO Output Set Point for correct voltage regulation.」

 

 

They measured CPU's core voltage levels with SABRE-EVK. But EVK doesn't satisfy the requirement.

Please see a following table.

 

Why EVK doesn't satisfy the requirement ?

NXP suppose that EVK is only for emulation use, so EVK deosen't satisfy the requirement.

Is it correct ?

 

As a result, user must set following register value to satisfy the requirement by themselves.

Is it correct ?

 

REG2_TARG

REG1_TARG

REG0_TARG
