GW1NSR-4C: is it possible to include the binary for the embedded CortexM3 along with the FPGA bitstream on boards like the Tang Nano 4K?

I have never tried to use the cortexM3, but it's possible with LiteX:

  • internal RAM is used for bitstream
  • external RAM is used for CPU bios Both case are handled by openFPGALoader

Thanks for the pointers I'll try to test this when I can, are there any special considerations to take for the .bin cortex m3 binary file?

in LiteX context everything is done to you (bitstream for the FPGA, bios for m3) and load is automatic with the correct option. I think it's a good starting point to deal with FPGA and CPU
