This project here is a further development of an existing XModem Bootloader which was also created for a DE0-Nano board but for a NIOS II CPU. With this project it should be possible to load a program into one of the different memories and start it there:
- XIP (Execute in Place memory, existing SPI flash on the DE0-Nano)
- IMEM (TCM, Tightly Coupled Memory)
- SDRAM
- SD Card to SDRAM (under development)
In addition, it should also be possible to update the FPGA image.
