## 1. Introduction
The instructions here will tell how to run mTower on the [NuMaker-PFM-M2351] board.

## 2. Regular build
Start out by following the "Get and build the solution" in the [build.md] file.
> Warning: Need to download the toolchain (exec. `make toolchain`).

## 3. Nuvoton NuMicro ICP Programming Tool
Please note that Nuvoton NuMicro ICP Programming Tool is used under Windows OS.
It can be downloaded from [here](https://m2351.nuvoton.com/resource/)

3. Once board successfully connects, chip ID and info will show in corresponding fields of window. Next you must select images to flash onto board. Click **"APROM"** button and select previously compiled file `mtower_s.hex` (secure world image), and click **"APROM_NS"** button and select `mtower_ns.hex` file (normal world image). Check the **"APROM"** and **"APROM_NS"** checkboxes in the bottom of window, in Programming group. Click the **"Start"** button to start flashing process.

5. Open console/terminal window (e.g., Putty) using 115200 speed setting with 8 bits with no parity check. Press **"Reset"** button on NuMaker-PFM-M2351 board, and you should see output in terminal window, like one shown below. Note that menu task is running in infinite loop, so the output shall not stop.
