Hi all
My customer did the power on/off test on their PCB,
he added below code to adjust PMIC output in u-boot,
he found PMIC will crash sometimes after i2c mw 0x2d 0x22 0x3f,
the PMIC_VDD1 output is 2.1V,
the normal voltage is 1.35V,
does anyone know this issue ?
and how to do the work around ?
Sincerely,
Max
