paulg 0:4ea2252690b9 2 * File: main.cpp
paulg 0:4ea2252690b9 3 * Author: Paul Griffith
paulg 0:4ea2252690b9 4 * Created: 27 May 2013
paulg 0:4ea2252690b9 5 * Last Edit: see below
paulg 0:4ea2252690b9 6 * Version: see below
paulg 0:4ea2252690b9 7 *
paulg 0:4ea2252690b9 8 * Description:
paulg 0:4ea2252690b9 9 * Test program to demonstrate application switching.
paulg 0:4ea2252690b9 10
paulg 0:4ea2252690b9 11 * This program loads and runs one of several different binaries.
paulg 0:4ea2252690b9 12 * The binaries are all present on the local filesystem, but are renamed to
paulg 0:4ea2252690b9 13 * app1.mbd, app2.mbd and so on. The filenames must conform to the local
paulg 0:4ea2252690b9 14 * filesystem's 8+3 filename rule and have an extension other then .bin.
paulg 0:4ea2252690b9 15 * This ensures that the files can be accessed by the local filesystem library
paulg 0:4ea2252690b9 16 * and that the interface chip does not act upon the binaries.
paulg 0:4ea2252690b9 17 * Another requirement is that all other .bin files must be deleted from the
paulg 0:4ea2252690b9 18 * local filesystem. This is necessary because downloaded files will always
paulg 0:4ea2252690b9 19 * have more recent timestamps than ones created by the local filesystem.
paulg 0:4ea2252690b9 20 * To switch applications, the current .bin file is deleted, the chosen app
paulg 0:4ea2252690b9 21 * file is copied to a .bin and the nR pin is driven low. The interface chip
paulg 0:4ea2252690b9 22 * then loads the .bin file into mbed's Flash.
paulg 0:4ea2252690b9 23 *
paulg 0:4ea2252690b9 24 * To use this program:
paulg 0:4ea2252690b9 25 * 1. From the PC, remove all .bin files from the mbed local filesystem,
paulg 0:4ea2252690b9 26 * 2. Compile as is, download to mbed and Flash it into mbed.
paulg 0:4ea2252690b9 27 * 3. From the PC, rename the binary to app1.mbd.
paulg 0:4ea2252690b9 28 * 4. Edit the MYNAME string to app2.bin
paulg 0:4ea2252690b9 29 * 5. Save, recompile and download to mbed. Do NOT Flash into mbed.
paulg 0:4ea2252690b9 30 * 6. From the PC, rename the binary to app2.mbd.
paulg 0:4ea2252690b9 31 * 7. Edit the MYNAME string to app3.bin
paulg 0:4ea2252690b9 32 * 8. Save, recompile and download to mbed. Do NOT Flash into mbed.
paulg 0:4ea2252690b9 33 * 9. From the PC, rename the binary to app3.mbd.
paulg 0:4ea2252690b9 34 * 10 Fit a wire jumper between mbed pin 9 (rstOut) and mbed pin 4 (nR).
paulg 0:4ea2252690b9 35 * Another mbed I/O pin can be used if you change the RSTPIN definition.
paulg 0:4ea2252690b9 36 * (If you don't fit a jumper you will have to press the Reset button
paulg 0:4ea2252690b9 37 * when the Resetting mbed module... prompt appears).
paulg 0:4ea2252690b9 38 *
paulg 0:4ea2252690b9 39 * The program can now be run. It uses the virtual serial port at 9600 baud
paulg 0:4ea2252690b9 40 * and has a simple command interpreter. All commands end with <Enter>.
paulg 0:4ea2252690b9 41 * Use the 1, 2 and 3 commands to switch applications.
