AUTO recovery
Automatically recovers the device from programming failure, Device power failure during programming.
自动使设备从编程失败中恢复,编程过程中设备断电.
For security and reliability reasons, the programming bitstream must be authenticated and
validated before the device is programmed. Successful authentication of the bitstream prevents
auto recovery.
出于安全性和可靠性考虑,在对设备进行编程之前,必须对编程比特流进行认证和验证。比特流认证成功会阻止自动恢复(流程)。
阻止自动恢复,这里应该解释为 若比特流无效,便可避免调用恢复流程。
As part of IAP recovery when power fails during IAP or partially programmed with an invalid image
作为 IAP 恢复机制的一部分,适用于以下场景:在 IAP 过程中发生断电,或设备被部分编程了一个无效的镜像。
As part of auto update recovery when power fails during auto update
作为自动更新恢复机制的一部分,适用于自动更新过程中发生断电的场景。
If the auto update program fails, the auto update recovery procedure attempts to program the device with the valid image again.
如果自动更新编程失败,自动更新恢复程序会尝试再次使用有效镜像对器件进行编程。
3.3.3.3. Recovery on Auto Update Programming Failure (Ask a Question)
When power fails during auto update programming, the auto update programming flow is initiated
on the next boot cycle to program the device with the newest image.
Note: If the device fails to program the newer image, it retries once before programming itself with
the older version of the image. If the device remains blank at the end of auto update, there is no
indication through I/O and user intervention is required.
