4.2i Data2BRAM - A Data2BRAM segmentation fault occurs when a direct bit file replacement is performed


Keywords: Data2BRAM, bit, segfault, seg fault, ELF, MEM

General Description:
When a BMM file contains address blocks for which no data exists (in either the ELF or MEM file), Data2BRAM will experience a segmentation fault. This only occurs when Data2BRAM is performing a direct bit file replacement.
