7 series Configuration - When Fallback is enabled, the device status register is always cleared after a failed configuration attempt

Description

When Fallback is enabled, the device status register is always cleared after a failed configuration attempt.

How doI debug my failed configuration?

Solution

The Fallback option is disabled by default for 7 series devices for Single Image flows. So, for a failed configuration attempt, you should see the correct Status Register with default options.You can ensure your design has Fallback disabled by checking your BitGenreport (<design_name>.bgn). The option to set Fallback is:

-g ConfigFallback : Enable|Disable

The default for multiboot flows is ConfigFallback:Enable
