[> Milkymist-NG system-on-chip
|
|
------------------------------
|
|
|
|
This is the next-generation Milkymist(tm) system-on-chip design,
|
|
introducing two key innovations:
|
|
* Built on the powerful Migen VLSI logic design system.
|
|
* Increased system memory performance thanks to a new architecture
|
|
(ASMI) containing a transaction-reordering and superscalar controller.
|
|
|
|
The Milkymist-NG SoC supports the Milkymist One board. Obtain yours at:
|
|
http://milkymist.org
|
|
|
|
Note that the -NG version is still experimental work in progress. For the
|
|
production version of Milkymist SoC, visit:

|
|
|
|
[> 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, FJMEM and UrJTAG.
|
|
These tools can be found at:
|
|
https://github.com/milkymist/fjmem-m1
|
|
http://urjtag.org
|
|
|
|
[> Instructions (gateware)
|
|
--------------------------
|
|
First, download and install Migen from:
|
|
https://github.com/milkymist/migen
|
|
|
|
Once this is done, build the bitstream with:
|
|
make
|
|
This will generate the build/soc.bit programming file.
|
|
Use:
|
|
make load
|
|
to load it with UrJTAG.
|
|
|
|
The SoC expects a bootloader to be located in flash at 0x860000, just
|
|
like the legacy SoC did. However, there is no binary compatibility and a
|
|
new BIOS needs to be built and flashed for the -NG SoC.
|
|
|
|
Enjoy!
