Hi Naftali,

Yes sir, you need to tick the "Auto restart configuration after error" in quartus in order for the quartus to configure to factory image when there is an error in configuring application image.

To boot into application / factory image at first, you will need to set the AnF bit.

For more information about remote update, you may refer to link below:

Thank You.

Regards,

Bruce

Hi Bruce,

Your answer is nice, but not to my question.

I understood that tick it cause the factory image to reconfigure when the application image is corrupt.

My question is what will stop the factory image from trying again and again after it reconfigured?

The flow now is this:

  1. factory image
  2. trying to configure the application image
  3. because of the error, the FPGA reconfigure the factory image
  4. trying again to configure the application image
  5. because of the error, the FPGA reconfigure the factory image

and so...

How can i stop it in stage 3, after it tried to configure the application image and failed and configure the factory image?

Thanx.
