GPU Voltage on IMX8MQuad EVK board

[coindu]

Hi All:

   The IMX8MQuad EVK board use PFUZE100 as PMIC IC.

   When viewing GPU and VPU voltages with an oscilloscope . I found the GPU voltage not always on .Is this part of the PMIC function?

   We want to use rohm,bd71837 instead of pfuze100 ，but the temperature is very high，so we compare the difference in voltage .

Hi coin

MC34PF4210 pmic is used on i.MX8M EVK board, one can look at GPU voltage connection on its schematic:
