Bypassing the Back Level Protection

If Back Level protection is enabled in the Configure Security tool, the back level protection can be bypassed for SPI bitstreams while exporting the bitstream using Libero. To prevent Programming Recovery failures, enable the Bypass the Back Level Protection for Recovery/Golden bitstream (SPI files only), as shown in the following figures.

Figure 1. Selecting Bypass Back Level Protection Feature

When the SPI bitstream is added to the SPI flash using design and memory initialization data, the tool shows back level protection bypass feature in bitstream, as shown in the following figure.
