This example shows how to generate the .mcs files for a multiboot design with the "golden" bitstream loaded at address 0 and the multiboot bitstream loaded at address 0x0100_0000.

Devices: 2x 256 Mib Quad SPI Flash devices: 256 Mib = 32 MiB

Total storage size: 2 * 32 MiB = 64 MiB

Load addresses:

  Golden: 0 * 2 = 0

  Multiboot: 0x0100_0000 * 2 = 0x0200_0000

    write_cfgmem -format mcs -interface spix8 -size 32 \
    -loadbit "up 0 ./design1_spix8.bit up 0x02000000 ./design2_spix8.bit" \
    -file design1_design2_spix8.mcs
