Hi @nxp,
We are working with a custom board based on the i.MX8MP, with a PMIC circuit similar to the EVK.
We have connected an LED board to the GPIO3_IO16 pin, as shown in the attached design, along with the PMIC circuit. However, we are observing an issue: there is leakage power to the LED board even when the system is in a shutdown state. Out of the total 8 LEDs, one LED still glows faintly during shutdown.
Could you please assist us in identifying and resolving the cause of this leakage power?
Thank you!
What kind of LED board are you using? Could you share us how it connect to i.MX8MP , you'd better share this section of the shematic to us
Hi @MJD ,
Could you share use all the i.MX8MP design to us? We need to check your design, to see the pins design in your side? Thanks
Sorry for late reply, I was on annual days leave and back to office now, I will following your questions now.
Wish you have a nice day
Best Regards
Rita
how it connect to i.MX8MP? Could you also share it? Thanks
We have connected DIN pin of LED board to the GPIO3_IO16 pin.
