Building and Installing the GNU Toolchain for the SCARTS Architecture

1. Prerequisites
|
| 5 |
|
|
----------------
|
| 6 |
|
|
|
| 7 |
|
|
1.1 Dependencies
|
| 8 |
|
|
----------------
|
| 9 |
|
|
The GNU Toolchain for the SCARTS architecture requires a bunch of packages
|
| 10 |
|
|
to be made available on a host machine prior to its installation. Note that
|
| 11 |
|
|
the following list of dependencies might vary slightly from host to host, but
|
| 12 |
|
|
should be suitable for most default Linux installations:
|
| 13 |
|
|
|
| 14 |
|
|
- gcc-4.1
|
| 15 |
|
|
- libtool
|
| 16 |
|
|
- termcap-devel
|
| 17 |
|
|
- texinfo
|
| 18 |
|
|
- zlib-devel
|
| 19 |
|
|
|
| 20 |
|
|
1.2 Resource Definition Script
|
| 21 |
|
|
------------------------------
|
| 22 |
|
|
Edit the resource file scartsrc in ./scripts and adapt the (top level) paths to
|
| 23 |
|
|
suit your needs. By sourcing the file in the terminal you make the variables in
|
| 24 |
|
|
scartsrc available in the environment:
|
| 25 |
|
|
|
| 26 |
|
|
. ~/scripts/scartsrc (mind the leading dot!)
|
| 27 |
|
|
|
| 28 |
|
|
1.3 PATH Environment Variable
|
| 29 |
|
|
-----------------------------
|
| 30 |
|
|
Edit the file .bashrc within your home folder and add the 'bin' directory of
|
| 31 |
|
|
the GNU Toolchain installation directory to $PATH, e.g. via:
|
| 32 |
|
|
|
| 33 |
|
|
export PATH=$PATH:/opt/scarts/bin
|
| 34 |
|
|
|
| 35 |
|
|
2. Building and Installation
|
| 36 |
|
|
----------------------------
|
| 37 |
|
|
For a fresh installation of the GNU toolchain for the SCARTS architecture you
|
| 38 |
|
|
must follow these steps (in chronological order):
|
| 39 |
|
|
|
| 40 |
|
|
2.1 scarts-memmap
|
| 41 |
|
|
-----------------
|
| 42 |
|
|
The SCARTS memory mapping tool allows for the management of memory mappings,
|
| 43 |
|
|
which depend on both the configured word size of the SCARTS processor and the
|
| 44 |
|
|
selected target platform, from simple configuration files.
|
| 45 |
|
|
|
| 46 |
|
|
The memory mapper automatically creates the dependencies (configuration files,
|
| 47 |
|
|
Makefiles, linker scripts, etc.) for a certain memory map in order that both
|
| 48 |
|
|
the SCARTS and the GNU toolchain may share the same view of the memory.
|
| 49 |
|
|
|
| 50 |
|
|
Although it is recommended to always keep the SCARTS and the GNU toolchain in
|
| 51 |
|
|
synch, only some of the dependencies are mandatory:
|
| 52 |
|
|
|
| 53 |
|
|
- SCARTS VHDL configuration file (scarts_conf.vhd)
|
| 54 |
|
|
- Makefile and linker scripts for the bootloader
|
| 55 |
|
|
- Makefile and linker scripts for applications
|
| 56 |
|
|
|
| 57 |
|
|
The simulator within the GDB, for example, uses a default memory configuration
|
| 58 |
|
|
which should be sufficiently large to suit most applications.
|
| 59 |
|
|
|
| 60 |
|
|
Please refer to the usage of the memory mapping tool for more information!
