[> MiSoC system-on-chip
2012-02-14 09:43:09 -05:00
------------------------------
A high performance and small footprint system-on-chip design based on Migen.
2012-02-14 09:43:09 -05:00
2013-11-09 09:27:32 -05:00
MiSoC supports the Mixxeo and the Milkymist One.

[> Instructions (software)
--------------------------
1. Compile and install binutils. Take the latest version from GNU.
2013-02-16 17:41:42 -05:00
mkdir build && cd build
../configure --target=lm32-elf
2012-06-03 16:17:34 -04:00
make
make install
2013-02-16 17:41:42 -05:00
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
2012-06-03 16:17:34 -04:00
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
2012-06-03 16:17:34 -04:00
4. Build and flash the BIOS (part of this source distribution).
2012-06-03 16:17:34 -04:00
cd software/bios
make
make flash
2013-07-31 17:29:26 -04:00
The second command requires m1nor-ng, FJMEM and UrJTAG.
2013-02-16 17:41:42 -05:00
These tools can be found at:

2012-06-03 16:20:50 -04:00

[> Instructions (gateware)
--------------------------
2012-02-14 09:43:09 -05:00
First, download and install Migen from:
2013-11-23 05:29:20 -05:00
https://github.com/m-labs/migen
2012-02-14 09:43:09 -05:00
Once this is done, build the bitstream with:
2013-07-04 13:19:39 -04:00
./make.py [-p <platform>] -l
This will generate the build/soc-<platform>.bit programming file
and load it with UrJTAG.
2012-02-14 09:43:09 -05:00
2013-11-09 09:27:32 -05:00
A new BIOS needs to be built and flashed for MiSoC.
There is no compatibility with Milkymist SoC.
2012-02-14 09:43:09 -05:00
Enjoy!
