+STM32H747 Discovery
+===================
+
+This tutorial describes how to use the predefined Buildroot
+configuration for the STM32H747 Discovery evaluation platform.
+
+Building
+--------
+
+  make stm32h747_disco_sd_defconfig
+  make
+
+Flashing
+--------
+
+  ./board/stmicroelectronics/stm32h747-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/stm32h747-disco/genimage.cfg.
