NOTE 2: The devkitARM toolchain includes a version of MSYS make. Make sure that The Atollic "Pro" and "Lite" Toolchain
--------------------------------------
One problem that I had with the Atollic toolchains is that the provide a gcc.exe
and g++.exe in the same bin/ file as their ARM binaries. If the Atollic bin/ path
appears in your PATH variable before /usr/bin, then you will get the wrong gcc
when you try to build host executables. This will cause to strange, uninterpretable
errors build some host binaries in tools/ when you first make.
Also, the Atollic toolchains are the only toolchains that have built-in support for
the FPU in these configurations. If you plan to use the Cortex-M4 FPU, you will
need to use the Atollic toolchain for now. See the FPU section below for more
information.
The Atollic "Lite" Toolchain
----------------------------
The free, "Lite" version of the Atollic toolchain does not support C++ nor
does it support ar, nm, objdump, or objdcopy. If you use the Atollic "Lite"
toolchain, you will have to set:
CONFIG_HAVE_CXX=n
In order to compile successfully. Otherwise, you will get errors like:
"C++ Compiler only available in TrueSTUDIO Professional"
The make may then fail in some of the post link processing because of some of
the other missing tools. The Make.defs file replaces the ar and nm with
the default system x86 tool versions and these seem to work okay. Disable all
of the following to avoid using objcopy:
CONFIG_RRLOAD_BINARY=n
CONFIG_INTELHEX_BINARY=n
CONFIG_MOTOROLA_SREC=n
CONFIG_RAW_BINARY=n

FPU
===
FPU Configuration Options
-------------------------
There are two version of the FPU support built into the most NuttX Cortex-M4
ports. The current LPC43xx port support only one of these options, the "Non-
Lazy Floating Point Register Save". As a consequence, CONFIG_ARMV7M_CMNVECTOR
must be defined in *all* LPC43xx configuration files.
1. Lazy Floating Point Register Save.
This is an untested implementation that saves and restores FPU registers
only on context switches. This means: (1) floating point registers are
not stored on each context switch and, hence, possibly better interrupt
performance. But, (2) since floating point registers are not saved,
you cannot use floating point operations within interrupt handlers.
This logic can be enabled by simply adding the following to your .config
file:
CONFIG_ARCH_FPU=y
2. Non-Lazy Floating Point Register Save
Mike Smith has contributed an extensive re-write of the ARMv7-M exception
handling logic. This includes verified support for the FPU. These changes
have not yet been incorporated into the mainline and are still considered
experimental. These FPU logic can be enabled with:
CONFIG_ARCH_FPU=y
CONFIG_ARMV7M_CMNVECTOR=y
You will probably also changes to the ld.script in if this option is selected.
This should work:
-ENTRY(_stext)
+ENTRY(__start) /* Treat __start as the anchor for dead code stripping */
+EXTERN(_vectors) /* Force the vectors to be included in the output */
CFLAGS
------
Only the Atollic toolchain has built-in support for the Cortex-M4 FPU. You will see
the following lines in each Make.defs file:
ifeq ($(CONFIG_LPC43_ATOLLIC_LITE),y)
# Atollic toolchain under Windows
...
ifeq ($(CONFIG_ARCH_FPU),y)
ARCHCPUFLAGS = -mcpu=cortex-m4 -mthumb -march=armv7e-m -mfpu=fpv4-sp-d16 -mfloat-abi=hard
else
ARCHCPUFLAGS = -mcpu=cortex-m3 -mthumb -mfloat-abi=soft
endif
endif
If you are using a toolchain other than the Atollic toolchain, then to use the FPU
you will also have to modify the CFLAGS to enable compiler support for the ARMv7-M
FPU. As of this writing, there are not many GCC toolchains that will support the
ARMv7-M FPU.
As a minimum you will need to add CFLAG options to (1) enable hardware floating point
code generation, and to (2) select the FPU implementation. You might try the same
options as used with the Atollic toolchain in the Make.defs file:
ARCHCPUFLAGS = -mcpu=cortex-m4 -mthumb -march=armv7e-m -mfpu=fpv4-sp-d16 -mfloat-abi=hard
Configuration Changes
---------------------
Below are all of the configuration changes that I had to make to configs/stm3240g-eval/nsh2
in order to successfully build NuttX using the Atollic toolchain WITH FPU support:
-CONFIG_ARCH_FPU=n : Enable FPU support
+CONFIG_ARCH_FPU=y
-CONFIG_LPC43_CODESOURCERYW=y : Disable the CodeSourcery toolchain
+CONFIG_LPC43_CODESOURCERYW=n
-CONFIG_LPC43_ATOLLIC_LITE=n : Enable *one* the Atollic toolchains
CONFIG_LPC43_ATOLLIC_PRO=n
-CONFIG_LPC43_ATOLLIC_LITE=y : The "Lite" version, OR
CONFIG_LPC43_ATOLLIC_PRO=y : The "Pro" version (not both)
-CONFIG_INTELHEX_BINARY=y : Suppress generation FLASH download formats
+CONFIG_INTELHEX_BINARY=n : (Only necessary with the "Lite" version)
-CONFIG_HAVE_CXX=y : Suppress generation of C++ code
+CONFIG_HAVE_CXX=n : (Only necessary with the "Lite" version)
See the section above on Toolchains, NOTE 2, for explanations for some of
the configuration settings. Some of the usual settings are just not supported
by the "Lite" version of the Atollic toolchain.
