Problem: it is not possible to assign an ELF files to the BRAM that we add in such way not directly in Vivado IPI. As workaround several options exist, we can create an BOOTROM IP Core that can be connected to the LMB Bus holding the bootcode or we can create a BOOSTRAP IP Core that writes the bootrom code into the main BRAM and then releases F32C reset. Of course it is possible to merge the ELF into bitstream with console commands or TCL scripting.
LMB Bootrom IP Core added with fixed code for the bootstrap.
