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/<your-sd-device> *** 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
