STM32F469 Discovery
===================
This tutorial describes how to use the predefined Buildroot
configuration for the STM32F469 Discovery evaluation platform.
Building
--------
make stm32f469_disco_sd_defconfig
make
Flashing
--------
./board/stmicroelectronics/stm32f469-disco/flash_sd.sh output/
It will flash the U-boot bootloader.
Creating SD card
----------------
Buildroot prepares an"sdcard.img" image in the output/images/ directory,
ready to be dumped on a SD card. Launch the following command as root:
dd if=output/images/sdcard.img of=/dev/
*** WARNING! This will destroy all the card content. Use with care! ***
For details about the medium image layout and its content, see the
definition in board/stmicroelectronics/stm32f469-disco/genimage.cfg.
Framebuffer
-----------
After Linux boots, /dev/fb0 will be accessible. You can control the
brightness of the display after enabling the framebuffer by running the
following commands:
# echo 0 0 > /sys/class/graphics/fb0/pan
# echo 255 >/sys/class/backlight/40016c00.dsi.0/brightness
The brightness ranges from 0 to 255, as you can see running the
command:
# cat /sys/class/backlight/40016c00.dsi.0/max_brightness
