-Subject: [PATCH] ARM: stm32f249-disco: don't force init= in /chosen/bootargs
-
-There is no reason to override the kernel's default init= value, as
-this breaks userspace that assumes the kernel default of /init is
-used. Since stm32 is often used with a minimal bootloader
-(afboot-stm32) that doesn't provide any mechanism to override the DTB,
-we need to adjust the kernel command line in the Device Tree source.

+
+  dd if=output/images/sdcard.img of=/dev/<your-sd-device>

+   # echo 255 >/sys/class/backlight/40016c00.dsi.0/brightness

+STM32F469 Discovery
+===================
+
+This tutorial describes how to use the predefined Buildroot
+configuration for the STM32F469 Discovery evaluation platform.
+
+Internal flash memory stores simple afboot-stm32 bootloader, device tree and
+in place (XIP) kernel with built-in initramfs. No external flash or SD card
+is needed.
+
+Kernel is based on tinyconfig.
