+# This file contains common pin mappings for the BigTreeTech SKR SE BX.
+# To use this config, the firmware should be compiled for the
+# STM32H743 with a "128KiB bootloader". Additionally, GPIO pins PB5
+# and PE5 need to be set at microcontroller startup.
+
+######################################################################
+# NOTE: In order enable the TFT70-BX display when the printer first
+# starts, add PB5 and PE5 to the `GPIO pins to set at micro-controller
+# startup` section when running "make menuconfig"
+######################################################################
+
+# The "make flash" command does not work on the SKR SE BX. Instead,
+# after running "make", copy the generated "out/klipper.bin" file to a
+# file named "firmware.bin" on an SD card and then restart the SKR SE BX
+# with that SD card. After klipper has been flashed once to the board,
+# you can update klipper by leaving a microSD inserted and running the
+# scripts/flash-sd.sh script.
+
+# See docs/Config_Reference.md for a description of parameters.
