[> MiSoC system-on-chip
------------------------------
A high performance system-on-chip design based on Migen.
MiSoC supports the Mixxeo and the Milkymist One.
Obtain your development system at http://milkymist.org
[> Instructions (software)
--------------------------
1. Compile and install binutils. Take the latest version from GNU.
mkdir build && cd build
../configure --target=lm32-elf
make
make install
2. Compile and install GCC 4.5. Take gcc-core and gcc-g++ from GNU.
rm -rf libstdc++-v3
mkdir build && cd build
../configure --target=lm32-elf --enable-languages="c,c++" --disable-libgcc --disable-libssp
make
make install
3. Obtain compiler-rt and set the CRTDIR environment variable to the root of
its source tree.
svn co http://llvm.org/svn/llvm-project/compiler-rt/trunk compiler-rt
export CRTDIR=/path_to/compiler-rt
4. Build and flash the BIOS (part of this source distribution).
cd software/bios
make
make flash
The second command requires m1nor-ng, FJMEM and UrJTAG.
These tools can be found at:
https://github.com/m-labs/fjmem-m1
http://urjtag.org
[> Instructions (gateware)
--------------------------
First, download and install Migen from:
https://github.com/m-labs/migen
Once this is done, build the bitstream with:
./make.py [-p <platform>] -l
This will generate the build/soc-<platform>.bit programming file
and load it with UrJTAG.
A new BIOS needs to be built and flashed for MiSoC.
There is no compatibility with Milkymist SoC.
Enjoy!
