Verify and load an app image (available only in space of bootloader). If encryption is enabled, data will be transparently decrypted. Image validation checks: - Magic byte. - Partition smaller than 16MB. - All segments & image fit in partition. - 8 bit image checksum is valid. - SHA-256 of image is valid (if image has this appended). - (Signature) if signature verification is enabled.
Syntax
Implemented in ![]()
esp_image_format.c:258
Return value
- ESP_OK if verify or load was successful - ESP_ERR_IMAGE_FLASH_FAIL if a SPI flash error occurs - ESP_ERR_IMAGE_INVALID if the image appears invalid. - ESP_ERR_INVALID_ARG if the partition or data pointers are invalid.

Description
Verify an app image. If encryption is enabled, data will be transparently decrypted. Image validation checks: - Magic byte. - Partition smaller than 16MB. - All segments & image fit in partition. - 8 bit image checksum is valid. - SHA-256 of image is valid (if image has this appended). - (Signature) if signature verification is enabled.
Update the partition and reboot_counter in rtc_retain_mem. This function saves the partition of application for fast booting from the deep sleep. An algorithm uses this partition to avoid reading the otadata and does not validate an image. Note: This function operates the RTC FAST memory which available only for PRO_CPU. Make sure that this function is used only PRO_CPU.
