Execute the following command to modify the bitstream file for MicroBlazeâ„¢ processor.

petalinux-package boot --fpga <FPGA bitstream> --fsbl <fs-boot> --format DOWNLOAD.BIT
This generates download.bit in the <plnx-proj-root>images/linux/ directory. The previous command merges the fs-boot into the FPGA bitstream by mapping the ELF data onto the memory map information (MMI) for the block RAMs in the design. For detailed usage, see the --help option or petalinux-package boot.
Note: PetaLinux only supports 32-bit MicroBlaze processors.
