> Seems rather application-specific. Have you considered the generic BOARDIOC_IOCTL instead?Sent from my Galaxy Yes, but it isn't too specific. If the board support A/B boot, something like BOARDIOC_SWITCH_BOOT is required to commuicate the boot partition from userspace(OTA subsystem) to board, so it's a common requirement for A/B boot: 1. Download the new image from the sever 2. Write the new image to the alternative partition 3. Call BOARDCTL_SWITCH_BOOT to the alternative system This is even useful in the single boot partition case, if we want to implement the reliable update: 1. Download the new image from the sever 2. Call BOARDCTL_SWITCH_BOOT and reboot to a small system 3. Write the new image to the main partition in the small system 4. Call BOARDCTL_SWITCH_BOOT again to the main system You can see that it's key point to allow updater switch the boot partition. -- This is an automated message from the Apache Git Service.
