This example demonstrates how to perform OTA updates for various partitions using the esp_https_ota component's APIs. The following partitions can be updated:

Application (app)
Bootloader
Partition Table
Storage

This example can be easily modified to perform OTA updates for any partition type.

⚠️ WARNING: Updating the bootloader and partition table is not safe. If the final copying to the destination partition is interrupted, the chip may fail to boot. Ensure that the final copy occurs only when power is stable and there is a low risk of errors.

OTA Update

Currently, there is no rollback mechanism for non-application partitions. In case of failure, only the application partition can safely rollback.

Application

Application OTA updates use one active and one passive partition. The new image is downloaded into the passive partition. Once the download is complete and verified, the device switches to the new image. This approach ensures that unexpected reboots during the update do not render the device unusable.

Bootloader

Bootloader OTA updates are not inherently safe because the ROM bootloader does not support fallback to a recovery bootloader partition. Only the primary bootloader partition can be loaded by the ROM bootloader. Updating the bootloader is rarely necessary, and it is generally not recommended. However, if required, it can be done using the following approaches:

Register the primary bootloader partition in the partition table, if not already present (see test/partitions_efuse_emul_2.csv).
Decide where to download the new bootloader image:
- Use a passive app partition, if app rollback is not used at the same time.
- Use a dedicated OTA bootloader partition (type=bootloader, subtype=ota). You can find unallocated flash space with partition_utils_find_unallocated().
- Download directly into the primary bootloader partition (this approach is highly unsafe).

After verification, if finalize_with_copy is set to true, the tool will automatically copy the new image to the primary bootloader partition. Set finalize_with_copy to false if you wish to control the final copy step manually.

Limitations for Bootloader OTA updates:

Secure Boot V1-enabled devices do not support bootloader updates.
There is always a risk of device bricking when updating the bootloader.

Partition Table

Updating the partition table via OTA is similarly unsafe because the bootloader cannot use a backup partition table in case of failure. If the update fails, the device will be unable to boot. Partition table updates are rarely needed, and caution is strongly advised. The workflow for partition table updates is the same as for the bootloader.

Storage

Updating storage partitions via OTA is also risky due to the potential for data loss in the partition. There is no fallback mechanism if an error occurs during the update. The workflow for Storage updates is the same as for the bootloader.

Configuration

Refer to the README.md file in the parent directory for setup instructions.

This example supports binding to a specific network interface ("Ethernet" or "WiFi Station") for firmware updates. You can configure this in idf.py menuconfig -> Example Configuration -> Support firmware upgrade bind specified interface -> Choose OTA data bind interface.

The CSV partition table file may include these entries at the beginning (see test/partitions_efuse_emul_2.csv):

PrimaryBTLDR, bootloader, primary, N/A, N/A, encrypted
PrimaryPrtTable, partition_table, primary, N/A, N/A, encrypted
