i.MX Device Tree Pinmux Settings Guide for System on Module
2021年4月29日 · Most i.MX SoC pins are multiplexed and offer up to 8 alternate pin functions. Additionally, most pins have configurable settings such as internal pull-ups, pull-downs, etc. This guide walks through how to configure a pin function and its settings for devices in the Linux device tree for Variscite i.MX System on Modules.

iMX8M-Plus using some GPIO inputs with internal pullups
2022年5月11日 · We observe that 100kohm external pull ups were not sufficient to pull the port pins up. Something on the SoM takes the IOs ( GPIO_SODIMM_30 and GPIO_SODIMM_32) down. I investigated the issue and realized that somehow u-boot device tree and linux kernel device tree which supposed to be totally isolated affect each other.
The ULPI transceiver includes on-chip series termination resistors and programmable pull-up/pull-down resistors for the D+ and D- lines. This implies that the D+/D- lines from the ULPI transceiver must be connected to the receptacle directly, and optional ESD circuit is recommended for the ULPI transceiver. 3.2 VBUS
