+# Toolchain
+Get a toolchain from [ARM's developer site](https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads)
+
+Extract this toolchain somewhere convenient.
+
+# Building this demo
+```
+cd armgcc
+ARMGCC_DIR=/path/to/gcc-arm-none-eabi ./build_release.sh
+```
+
+Output files will be in the release folder. There will be an ELF file (if you want to debug), and a bin file to upload to your device.
+
+# Running the demo
+## Deploy the binary to your device
+### On your host machine:
+```
+mdt push armgcc/release/hello_world_tflite.bin
+```
+
+### On the device:
+```
+sudo cp hello_world_tflite.bin /boot
+cd /boot
+sudo ln -sf hello_world_tflite.bin m4_fw.bin
+```
+
+### On the device, in u-boot:
+```
+setenv m4enabled 1
+saveenv
+boot
+```
+
+Output from the M4 core will be visible on the second UART that enumerated when you connected your serial port via USB.

-Overview
-========
-The Hello World demo application provides a sanity check for the new SDK build environments and board bring up. The Hello
-World demo prints the "Hello World" string to the terminal using the SDK UART drivers. The purpose of this demo is to
-show how to use the UART, and to provide a simple project for debugging and further development.
-Note: Please input one character at a time. If you input too many characters each time, the receiver may overflow
-because the low level UART uses simple polling way for receiving. If you want to try inputting many characters each time,
-just define DEBUG_CONSOLE_TRANSFER_NON_BLOCKING in your project to use the advanced debug console utility.

-Prepare the Demo
-================
-1.  Connect 12V power supply and J-Link Debug Probe to the board, switch SW701 to power on the board
-2.  Connect a USB cable between the host PC and the J1701 USB port on the target board.
-3.  Open a serial terminal with the following settings:
-    - 115200 baud rate
-    - 8 data bits
-    - No parity
-    - One stop bit
-    - No flow control
-4.  Download the program to the target board.
-5.  Launch the debugger in your IDE to begin running the demo.
