How Are Car Software Updates Downloaded and Installed? Is the Process Seamless?

Car software updates are typically downloaded and installed over-the-air (OTA), and the process aims to be as seamless as possible. At CAR-SCAN-TOOL.EDU.VN, we understand the importance of keeping your vehicle’s software up-to-date for optimal performance and security, and this article explores how this is achieved. Dive in to discover more about car software updates and how automotive scanner training can help you understand and manage them effectively, enhancing your skills in remote technician education and automotive diagnostics.

1. What Are Seamless Updates (A/B System Updates) in Cars?

Seamless updates, also known as A/B system updates, ensure that a working booting system remains on the disk during an over-the-air (OTA) update, reducing the risk of an inactive device post-update. According to a study by the University of Michigan’s Transportation Research Institute, OTA updates can reduce downtime and improve vehicle performance.

Alt: A/B system update process showing switching between slots A and B during an OTA update.

Benefits of A/B System Updates:

• OTA updates can occur while the system is running, minimizing interruption to the user.
• Rebooting after an update takes no longer than a regular reboot.
• If an OTA fails, the user remains on the old OS, and the update can be re-attempted.
• The device reboots into the old partition if the new OS fails to boot, maintaining usability.
• Errors affect only the unused partition set and can be retried.
• Updates can be streamed, eliminating the need to download the entire package before installation.
• The cache partition isn’t used for OTA packages, so there is no need to ensure a large cache partition.
• dm-verity guarantees a device will boot an uncorrupted image, allowing a reboot to an old image if needed.

2. How Do A/B System Updates Work?

A/B updates involve changes to both the client and the system but do not require changes to the OTA package server. Google’s OTA infrastructure handles system changes within AOSP, and Google Play services provide the client code.

Client Responsibilities for A/B Updates:

• Decide when to take an update, ideally during idle maintenance mode (e.g., overnight on Wi-Fi).
• Check with OTA package servers to determine update availability, signaling A/B support.
• Call update_engine with the HTTPS URL for the update package.
• Report installation successes or failures to the servers, based on the update_engine result code.

Optional Client Actions:

• Show a notification asking the user to reboot.
• Show a notification telling users whether they booted into a new OS version or fell back to the old OS version.

3. What System Changes Are Involved in A/B System Updates?

On the system side, A/B system updates affect:

• Partition selection (slots)
• The update_engine daemon
• Bootloader interactions
• Build process and OTA update package generation

4. How Does Partition Selection (Slots) Work in A/B Updates?

A/B system updates use two sets of partitions, referred to as slots (typically slot A and slot B). The system runs from the current slot, while the partitions in the unused slot are not accessed during normal operation, making updates fault-resistant.

Key Aspects of Partition Selection:

• Each slot has a bootable attribute, indicating whether it contains a correct system for booting.
• One slot is the active slot (the one the bootloader will boot from on the next boot) or the preferred slot.
• Each slot has a successful attribute, relevant only if the slot is also bootable, indicating it can boot, run, and update itself.
• Unsuccessful bootable slots should be marked as unbootable by the bootloader, switching the active slot to another bootable slot.

Alt: Diagram illustrating partition selection in A/B updates with slots A and B.

5. What is the Role of the Update Engine Daemon?

The update_engine daemon prepares the system to boot into a new, updated version.

Actions Performed by Update Engine:

• Read from the current slot A/B partitions and write data to the unused slot A/B partitions as instructed by the OTA package.
• Call the boot_control interface in a pre-defined workflow.
• Run a post-install program from the new partition after writing all unused slot partitions.

Update Engine Limitations:

The update_engine daemon is limited by the SELinux policies and features in the current slot, meaning it should not modify the partition table, the contents of partitions in the current slot, or the contents of non-A/B partitions that can’t be wiped with a factory reset.

6. Where Can I Find the Update Engine Source and Logs?

The update_engine source is located in system/update_engine.

Accessing Update Engine Logs:

For Android 8.x releases and earlier, the update_engine logs can be found in logcat and in the bug report. Patches can be applied to save a copy of the most recent update_engine log to /data/misc/update_engine_log/update_engine.<YEAR>-<TIME>.

7. How Do Bootloader Interactions Work in A/B Updates?

The boot_control HAL instructs the bootloader what to boot from.

Common Scenarios and States:

• Normal case: The system runs from the current slot (A or B), which is bootable, successful, and active.
• Update in progress: The system runs from slot B, which is bootable, successful, and active. Slot A is marked as unbootable.
• Update applied, reboot pending: The system runs from slot B, which is bootable and successful. Slot A is marked as active and bootable but not yet successful.
• System rebooted into new update: The system runs from slot A for the first time. Slot B is still bootable and successful, while slot A is only bootable, active, but not successful until update_verifier marks it as successful.

8. What is Streaming Update Support and Why is it Important?

Streaming A/B updates write blocks directly to the B partition as they are downloaded, without storing them on /data, addressing the issue of insufficient space on user devices. This requires almost no temporary storage (roughly 100 KiB of metadata).

Enabling Streaming Updates:

Patches are required to support streaming A/B updates in Android 7.1 and later, whether using Google Mobile Services (GMS) or any other update client.

9. What is the Life Cycle of an A/B Update?

The update process starts when an OTA package (payload) is available. Policies may defer download and application based on battery level, user activity, charging status, or other factors. The process may be interrupted at any point due to these policies, unexpected reboots, or user actions.

Update Process Steps:

1. The current slot (source slot) is marked as successful (if not already marked) with markBootSuccessful().
2. The unused slot (target slot) is marked as unbootable by calling setSlotAsUnbootable().
3. The payload metadata is downloaded.
4. For each operation in the metadata, the associated data (if any) is downloaded to memory, the operation is applied, and the memory is discarded.
5. The whole partitions are re-read and verified against the expected hash.
6. The post-install step (if any) is run.
7. The unused slot is marked as active by calling setActiveBootSlot().
8. Post-installation involves running a program from the “new update” version while still running in the old version.
9. After the system successfully boots far enough into the new slot and finishes the post-reboot checks, the now current slot (formerly the “target slot”) is marked as successful by calling markBootSuccessful().

Step	Activities
1	The current slot (or “source slot”) is marked as successful (if not already marked) with markBootSuccessful().
2	The unused slot (or “target slot”) is marked as unbootable by calling the function setSlotAsUnbootable(). The current slot is always marked as successful at the beginning of the update to prevent the bootloader from falling back to the unused slot, which will soon have invalid data. If the system has reached the point where it can start applying an update, the current slot is marked as successful even if other major components are broken (such as the UI in a crash loop) as it is possible to push new software to fix these problems. The update payload is an opaque blob with the instructions to update to the new version. The update payload consists of the following: – Metadata. A relatively small portion of the update payload, the metadata contains a list of operations to produce and verify the new version on the target slot. For example, an operation could decompress a certain blob and write it to specific blocks in a target partition, or read from a source partition, apply a binary patch, and write to certain blocks in a target partition. – Extra data. As the bulk of the update payload, the extra data associated with the operations consists of the compressed blob or binary patch in these examples.
3	The payload metadata is downloaded.
4	For each operation defined in the metadata, in order, the associated data (if any) is downloaded to memory, the operation is applied, and the associated memory is discarded.
5	The whole partitions are re-read and verified against the expected hash.
6	The post-install step (if any) is run. In the case of an error during the execution of any step, the update fails and is re-attempted with possibly a different payload. If all the steps so far have succeeded, the update succeeds and the last step is executed.
7	The unused slot is marked as active by calling setActiveBootSlot(). Marking the unused slot as active doesn’t mean it will finish booting. The bootloader (or system itself) can switch the active slot back if it doesn’t read a successful state.
8	Post-installation (described below) involves running a program from the “new update” version while still running in the old version. If defined in the OTA package, this step is mandatory and the program must return with exit code 0; otherwise, the update fails.
9	After the system successfully boots far enough into the new slot and finishes the post-reboot checks, the now current slot (formerly the “target slot”) is marked as successful by calling markBootSuccessful().

10. What Does Post-Installation Involve?

For every partition where a post-install step is defined, update_engine mounts the new partition into a specific location and executes the program specified in the OTA relative to the mounted partition.

Alt: Post-installation process showing mounting the new partition and executing the specified program.

Requirements for Post-Installation Success:

• The old kernel must be able to mount the new filesystem format.
• The old kernel must understand the new partition’s post-install program format.

Limitations of Post-Installation:

The new post-install program is limited by the SELinux policies defined in the old system. It is suitable for performing tasks required by design or other best-effort tasks but not suitable for one-off bug fixes before reboot that require unforeseen permissions.

SELinux Context:

The selected post-install program runs in the postinstall SELinux context, and all files in the new mounted partition are tagged with postinstall_file.

11. What Happens After Reboot?

After rebooting, update_verifier triggers the integrity check using dm-verity before zygote to avoid Java services making irreversible changes that would prevent a safe rollback. The bootloader and kernel may also trigger a reboot if verified boot or dm-verity detect any corruption. After the check completes, update_verifier marks the boot successful.

Integrity Check:

update_verifier will read only the blocks listed in /data/ota_package/care_map.txt, which is included in an A/B OTA package when using the AOSP code. The Java system update client extracts care_map.txt, sets up the access permission before rebooting the device, and deletes the extracted file after the system successfully boots into the new version.

12. How to Troubleshoot Common Software Update Issues?

Troubleshooting software update issues often involves diagnosing failures in the update process. Common problems include failed installations, boot failures, and performance issues after an update. Here’s a systematic approach to identify and resolve these issues:

1. Checking Logs

Purpose: To identify the exact point of failure and any error messages associated with it.

• Steps:
  • Access system logs using tools like logcat or by retrieving logs from /data/misc/update_engine_log/ (if available).
  • Look for entries related to update_engine, boot_control, or update_verifier.
  • Analyze error codes and messages to understand the cause of the failure.

Example:
If the log shows an INSTALL_FAILED error, it indicates a problem during the installation phase, such as a corrupted package or insufficient storage.

2. Verifying Partition Status

Purpose: To ensure that the correct partitions are active and bootable.

• Steps:
  • Use the boot_control HAL to check the status of slots A and B.
  • Confirm which slot is marked as active and whether it is bootable and successful.
  • If the active slot is not bootable or successful, it might indicate a failed update attempt.

Example:
If slot A is active but marked as unbootable, the device may fail to boot from it, and the bootloader should switch back to slot B.

3. Examining Bootloader Interactions

Purpose: To understand how the bootloader is handling the boot process and whether it is correctly switching between slots.

• Steps:
  • Monitor the boot process to see which slot the bootloader attempts to boot from.
  • Check if the bootloader correctly falls back to the previous slot after a failed boot attempt from the new slot.

Example:
If the bootloader continuously tries to boot from a corrupted slot, it may be necessary to manually intervene and force it to boot from the known good slot.

4. Checking dm-verity and Integrity Checks

Purpose: To ensure that the system image is not corrupted.

• Steps:
  • Monitor the update_verifier logs to see if the integrity check using dm-verity passes or fails.
  • If the integrity check fails, it indicates that the system image is corrupted and needs to be re-flashed.

Example:
If dm-verity detects corruption, the device will likely reboot, and the system should attempt to boot from the previous slot.

5. Analyzing Post-Installation Scripts

Purpose: To verify that post-installation scripts are running correctly and not causing failures.

• Steps:
  • Check the logs to see if the post-installation script executed successfully.
  • Ensure that all dependencies and required resources are available for the script to run.
  • If the script fails, analyze the error messages to identify the cause and correct the script.

Example:
If a post-installation script fails due to missing libraries, ensure that the libraries are included in the new system image or that the script is compatible with the old kernel.

6. Ensuring Sufficient Storage

Purpose: To make sure there is enough space for updates.

• Steps:
  • Verify that both system partitions (A and B) have sufficient space for the update.
  • If streaming updates are used, ensure that there is enough space for metadata.

Example:
If there is insufficient space on the target partition, the update will fail, and the logs will indicate a storage-related error.

7. Checking Network Connectivity

Purpose: To ensure the device can reliably download the update package.

• Steps:
  • Verify that the device is connected to a stable Wi-Fi network.
  • Check for any network restrictions or firewalls that may be blocking the update server.

Example:
If the device is intermittently losing connection to the network, the download may be interrupted, leading to a corrupted update package.

8. Confirming Compatibility

Purpose: To verify the update is compatible with the device’s hardware and software configuration.

• Steps:
  • Check the update package to ensure it is designed for the specific device model and Android version.
  • Verify that there are no known compatibility issues that could cause the update to fail.

Example:
Installing an update package designed for a different device model can lead to serious issues and may render the device unusable.

9. Reviewing SELinux Policies

Purpose: To confirm SELinux policies are not blocking update processes.

• Steps:
  • Review SELinux policies to ensure they are not overly restrictive and are allowing the necessary operations during the update.
  • Check if the postinstall context has the required permissions to execute post-installation scripts.

Example:
If SELinux policies are blocking access to certain files or directories, the update process may fail.

10. Factory Reset

Purpose: As a last resort, to clear any potentially conflicting data or settings.

• Steps:
  • Perform a factory reset to restore the device to its original state.
  • Attempt the update again after the reset.

Caution:
Factory reset will erase all user data, so it should be performed only after backing up important information.

By systematically following these troubleshooting steps, technicians can effectively diagnose and resolve common software update issues, ensuring devices remain functional and up-to-date.
