I want to update the generated bitstream after making changes in the .elf file, such that I don't have to go through the synthesis and implementation process again as the only part that's changed in my design is the contents of the memory, and I want to be able to see the changes made in .elf file after programming the FPGA with the new bitstream.
Note that I am not using the MicroBlaze embedded processor.

Hi @vmistry1 ,
you can use updatemem command to merge the bit stream and elf. please check the command below:
updatemem -force --meminfo C:/cases/non_processor_mmi/project_1.runs/impl_1/design_1_wrapper.mmi --data <path to data file>.elf/mem --bit <path to input bit> --proc dummy --out <output bit file>.bit

Thank you so much for reaching out.
How do I create the .mmi file and by design_wrapper, do you mean the wrapper for the whole design or just the memory module? I used the "write_mem_info" to do so and I'm getting the following error
