[GPIO-3.6] For Pads With Both GPIO and RTC_GPIO Functionality, the GPIO Pull-up and Pull-down Configuration Register Fields Are Nonfunctional

Affected revisions: v0.0 v1.0 v1.1 v3.0 v3.1

Description

GPIO pull-up and pull-down resistors for pads with both GPIO and RTC_GPIO functionality can only be controlled via RTC_GPIO registers.

Workarounds

Use RTC_GPIO registers for both GPIO and RTC_GPIO functions.

Solution

This issue is automatically worked around when using GPIO drivers in ESP-IDF v2.1 or newer.
