This configuration derives from the ostest configuration. It has
|
||||
been modified to us apps/examples/elf in order to test the ELF
|
||||
loader.
|
||||
|
||||
NOTES:
|
||||
|
||||
1. This configuration uses the mconf-based configuration tool. To
|
||||
change this configuration using that tool, you should:
|
||||
|
||||
a. Build and install the mconf tool. See nuttx/README.txt and
|
||||
misc/tools/
|
||||
|
||||
b. Execute 'make menuconfig' in nuttx/ in order to start the
|
||||
reconfiguration process.
|
||||
|
||||
2. Default toolchain:
|
||||
|
||||
CONFIG_STM32_CODESOURCERYW=y : CodeSourcery under Windows

3. By default, this project assumes that you are *NOT* using the DFU

NOTES:

1. This configuration uses the mconf-based configuration tool. To

change this configuration using that tool, you should:
|
||||
|
||||
CONFIG_STM32_CODESOURCERYL=y : CodeSourcery under Linux / Mac OS X
|
||||
a. Build and install the mconf tool. See nuttx/README.txt and

misc/tools/
|

|

If you use the Atollic toolchain, then the FPU test can be enabled in the
|

examples/ostest by adding the following your NuttX configuration file:
|

b. Execute 'make menuconfig' in nuttx/ in order to start the
|

reconfiguration process.
|

-CONFIG_ARCH_FPU=n : Enable FPU support

4. If you use the Atollic toolchain, then the FPU test can be enabled in the

|
||||
CONFIG_STM32_ATOLLIC_PRO=n : The "Pro" version
|
||||
|
||||
The FPU test also needs to know the size of the FPU registers save area in
