From 0bafdaf5f0f44295597cf2db8c36447675183339 Mon Sep 17 00:00:00 2001 From: Glenn Moloney Date: Thu, 17 Aug 2023 13:24:25 +1000 Subject: esp32: Skip validation of image on boot from deepsleep. sdkconfig.base: Add CONFIG_BOOTLOADER_SKIP_VALIDATE_IN_DEEP_SLEEP=y. This reduces time to boot from deepsleep by at least 200ms and can provide significant power savings for deepsleep-based battery applications. docs/library/esp32.rst: Add note cautioning not to enter deepsleep after changing the boot partition, without first performing a hard reset.
