8.6 Bios Recovery
If a Bios update will be interrupted (e.g due to power loss) before the update has finished, it can happen that the system will not boot.
In this case it is possible to restore the Bios with the following method:
1. Prepare the SPI Image (flashimg.bin) as described in section 8.1.
2. Short the recovery pins as seen in chapter 8.8.
3. Power on the system.
4. Bios will search for the Image file and if found a Bios recovery will be started.
5. After a few seconds you can release the recovery pins.
6. After Bios recovery is finished the system will perform a powercycle and the system should boot normal again without the recovery medium.
(If you have a POST display: Power ON - POST 32 - POST F5 - Power cycle)
NOTICE: During Bios recovery there is no video output. Users have to wait until power cycle will be performed.
So it is recommended to wait some minutes until power cycle is performed.
