Memory Map
|
||||
=========
|
||||
|
||||
Calypso has 256KB of internal SRAM (0x800000-0x83ffff). Only this internal SRAM
|
||||
is used by these configurations. The internal SRAM is broken up into three
|
||||
logic banks.
|
||||
|
||||
LRAM (rw) : ORIGIN = 0x00800000, LENGTH = 0x00020000
|
||||
TRAM (rw) : ORIGIN = 0x00820000, LENGTH = 0x00010000
|
||||
IRAM (rw) : ORIGIN = 0x00830000, LENGTH = 0x00010000
|
||||
|
||||
Code can be loaded by the bootloader only into TRAM and, hence, is restricted
|
||||
to 64KB. The additional 64KB if IRAM may be used for uninitialized data and
|
||||
for the NuttX heap only.

NuttX OABI "buildroot" Toolchain
|
||||
================================
|
||||
|
||||
A GNU GCC-based toolchain is assumed. The files */setenv.sh should
|
||||
be modified to point to the correct path to the ARM GCC toolchain (if
|
||||
different from the default in your PATH variable).
|
||||
|
||||
If you have no ARMtoolchain, one can be downloaded from the NuttX
|
||||
SourceForge download site (https://sourceforge.net/projects/nuttx/files/buildroot/).
|
||||
This GNU toolchain builds and executes in the Linux or Cygwin environment.
|
||||
|
||||
1. You must have already configured Nuttx in <some-dir>/nuttx.
|
||||
|
||||
cd tools
|
||||
./configure.sh pirelli_dpl10/<sub-dir>
|
||||
|
||||
2. Download the latest buildroot package into <some-dir>
|
||||
|
||||
3. unpack the buildroot tarball. The resulting directory may
|
||||
have versioning information on it like buildroot-x.y.z. If so,
|
||||
rename <some-dir>/buildroot-x.y.z to <some-dir>/buildroot.
|
||||
|
||||
4. cd <some-dir>/buildroot
|
||||
|
||||
5. cp configs/arm7tdmi-defconfig-4.3.3 .config
|
||||
|
||||
6. make oldconfig
|
||||
|
||||
7. make
|
||||
|
||||
8. Edit setenv.h, if necessary, so that the PATH variable includes
|
||||
the path to the newly built binaries.
|
||||
|
||||
See the file configs/README.txt in the buildroot source tree. That has more
|
||||
details PLUS some special instructions that you will need to follow if you are
|
||||
building a Cortex-M3 toolchain for Cygwin under Windows.
|
||||
|

Generic OABI Toolchain
|
||||
======================
|
||||
|
||||
The NuttX OABI toolchain is selected with:
|
||||
|
||||
CONFIG_ARM_TOOLCHAIN_BUILDROOT=y
|
||||
CONFIG_ARM_OABI_TOOLCHAIN=y
|
||||
|
||||
In most cases, OsmocomBB is built with a different OABI toolchain with a
|
||||
prefix of arm-elf-. To use that toolchain, change the configuration as
|
||||
follows:
