MiSoC comes with built-in targets for a few boards containing devices from all major FPGA vendors. Support for other boards can easily be added as external modules. [> Quick start guide -------------------- 0. If cloned from Git without the --recursive option, get the submodules: git submodule update --init 1. Install Python 3.3+, Migen and FPGA vendor's development tools. Get Migen from: https://github.com/m-labs/migen 2. Install JTAG tools. For Mixxeo and M1: http://urjtag.org For Papilio Pro and KC705: http://xc3sprog.sourceforge.net For De0 Nano: USBBlaster from Altera 3. (Optional, only needed if you want to flash the bitstream/BIOS/software) Obtain and build any required flash proxy bitstreams. Flash proxy bitstreams give JTAG access to a flash chip through the FPGA. For Mixxeo and M1: https://github.com/m-labs/fjmem-m1 For Papilio Pro: https://github.com/GadgetFactory/Papilio-Loader (xc3sprog/trunk/bscan_spi/bscan_spi_lx9_papilio.bit) For KC705: https://github.com/m-labs/bscan_spi_kc705 4. Compile and install binutils. Take the latest version from GNU. mkdir build && cd build ../configure --target=lm32-elf make make install 5. Compile and install GCC. Take gcc-core and gcc-g++ from GNU (version 4.5 or >=4.9). rm -rf libstdc++-v3 mkdir build && cd build ../configure --target=lm32-elf --enable-languages="c,c++" --disable-libgcc \ --disable-libssp make make install 6. Install MiSoC with: python3 setup.py install 7. Build the bitstream and BIOS for your board by executing the corresponding target file (see misoc/targets), e.g. python3 -m misoc.targets.kc705 Use the -h flag to see options. This will create a folder named e.g. misoc_basesoc_kc705 and build the BIOS and bitstream there. If your target uses BIOS execute-in-place, flash it. Load the bitstream. 7. Run a terminal program on the board's serial port at 115200 8-N-1. You should get the BIOS prompt. 8. Read and experiment with the source! Come to our IRC channel and mailing list! 9. Contribute a patch! Once you have experimented with stuff, please send your results back. For more details on how to do so, you can see the CONTRIBUTING.rst file.

Even though we do not require you to do so, those things are awesome, so please do them if possible: * tell us that you are using MiSoC * cite MiSoC in publications related to research it has helped * send us feedback and suggestions for improvements * send us bug reports when something goes wrong * send us the modifications and improvements you have done to MiSoC. The use of "git format-patch" is recommended. If your submission is large and complex and/or you are not sure how to proceed, feel free to discuss it on the mailing list or IRC (#m-labs on Freenode) beforehand.
