I use imx8m plus chip, my device has 5 relays, when the device is just powered on, the gpio of these 5 relays will be pulled up for a period of time, and will be pulled up in the spl stage before the uboot is started. How can I solve this problem
Hello @meeeeeei
You can take this AN14205 for reference. That is for imx93 but the process is the same fot imx8MP.

Hi @Alejandro_Salas
I control gpio in spl.c, but it doesn't work, is there any place I can control it earlier than this?
