Vikram Dattu caa1ef0cb6 Bugfix: ota fails with secure boot on for image size greater than 3.2MB When an OTA image size is larger than 50 MMU pages (approx. 3.2 MB), secure_boot_generate fails while trying to map it into memory: https://github.com/espressif/esp-idf/blob/master/components/bootloader_support/src/esp32/secure_boot.c#L72 Instead of trying to map the whole image, secure boot code should split the image into chunks and map them one by one, like it is done in esp_image_format.c: https://github.com/espressif/esp-idf/blob/master/components/bootloader_support/src/esp_image_format.c#L371 Signed-off-by: Vikram Dattu <vikram.dattu@espressif.com>		2019-08-05 05:34:11 +00:00

Bootloader Support Component
============================

Overview
--------

"Bootloader support" contains APIs which are used by the bootloader but are also needed for the main app.

Code in this component needs to be aware of being executed in a bootloader environment (no RTOS available, BOOTLOADER_BUILD macro set) or in an esp-idf app environment (RTOS running, need locking support.)
