![]() The WAKEUP_X pins are always an input no matter the pinmux mode. However, the 18th bit that typical configures a pin as an input is considered reserved for the WAKEUP_X pins. Therefore, for any WAKEUP pin remove any configuration that sets that pin as an input. Since those pins are only inputs remove any output configuration from those pins.

Summary ======= This document covers various features of the 'dra7xx_evm' build and some related uses. eMMC boot partition use ======================= It is possible, depending on SYSBOOT configuration to boot from the eMMC boot partitions using (name depending on documentation referenced) Alternative Boot operation mode or Boot Sequence Option 1/2. In this example we load MLO and u-boot.img from the build into DDR and then use 'mmc bootbus' to set the required rate (see TRM) and 'mmc partconfig' to set boot0 as the boot device.
