CONFIGURATION
=============
fb
--
A simple configuration used for some basic (non-graphic) debug of the
framebuffer character drivers using apps/examples/fb. This
configuration enables SDRAM to hold the LCD framebuffer and enables
the LPC178x LCD driver in order to support the WaveShare 4.3 inch TFT
panel.
NOTES:
1. This configuration uses the mconf-based configuration tool. To
change this configuration using that tool, you should:
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
see additional README.txt files in the NuttX tools repository
README.txt.
b. Execute 'make menuconfig' in nuttx/ in order to start the
reconfiguration process.
2. This configuration uses the "GNU Tools for ARM Embedded Processors"
that is maintained by ARM:
https://developer.arm.com/open-source/gnu-toolchain/gnu-rm
That toolchain selection can easily be reconfigured using
'make menuconfig'. Here are the relevant current settings:
Build Setup:
CONFIG_HOST_WINDOWS=y : Window environment
CONFIG_WINDOWS_CYGWIN=y : Cywin under Windows
System Type -> Toolchain:
CONFIG_ARMV7M_TOOLCHAIN_GNU_EABIW=y : GNU ARM EABI toolchain
3. In this configuration, the SDRAM is not added to heap but is
dedicated to supporting an LCD frame buffer at address 0xa0010000.
