This project is configure to get you up and running quickly using
5
CodeWarrior with the Freescale MCF52259 board.
6
 
7
This project provides full support for the selected board.
8
The created project provides Standard IO Support through console and terminal window.

10
Sample code for the following language:
11
- C

// Memory Maps
16
//------------------------------------------------------------------------
17
The Hardware has the following memory map:
18
 
19
# MCF52259 Derivative Memory map definitions from linker command files:
20
# __IPSBAR, __RAMBAR, __RAMBAR_SIZE, __FLASHBAR, __FLASHBAR_SIZE linker
21
# symbols must be defined in the linker command file.
22
 
23
# Memory Mapped Registers (IPSBAR= 0x40000000)
24
   ___IPSBAR         = 0x40000000;
25
 
26
# 32 Kbytes Internal SRAM
27
   ___RAMBAR         = 0x20000000;
28
   ___RAMBAR_SIZE    = 0x00008000;

# 512 KByte Internal Flash Memory
31
   ___FLASHBAR       = 0x00000000;

39
The project generated contains various files/groups:
40
- readme.txt: information for this project
41
- Sources: application source codes, user customizable startup
42
  code, uart library, exception table
43
- Includes: derivative and board header files, ...
44
- Libs: runtime and libs
45
- Project Settings: linker command files for the different build
46
  targets, the initialization and memory configuration files for
47
  the hardware debugging, the common startup code, etc...

// Build Targets
51
//------------------------------------------------------------------------
52
- CONSOLE_INTERNAL_RAM:
53
This project target is setup to load and debug code from internal RAM.
54
It should be used during your application development.
55
The application outputs to the CodeWarrior's console window.
56
 
57
- INTERNAL_RAM:
58
This project target is setup to load and debug code from internal RAM.
59
It should be used during your application development.
60
This is the very basic project that outputs to the UART.
61
You needs to connect a Terminal Program to see the output.
62
 
63
- INTERNAL_FLASH:
64
This project target is setup to load and debug code in Internal FLASH.
65
This is the very basic project that outputs to the UART. User needs
66
to connect the terminal to see the output.

===================================================================
71
WARNING regarding debugging new project wizard code with CCS-SIM
72
===================================================================
73
The CCS-SIM is an instruction set simulator, it does not implement
74
any peripherals.
75
The new project generated by the wizard are using startup code
76
performing some hardware peripheral initializations.
77
When debugging with the CCS-SIM  it might happen that the simulation
78
stuck on loop using non implemented peripheral register flag as
79
condition (PLL initialization as example).
80
In this case, you should either:
81
- move the PC to next statement
82
- use a skip point
83
- define a simulator specific macro which used when define allos you
84
to comment out the unwanted code in order to debug with CCS-SIM
85
 
86
 
87
===================================================================
88
WARNING regarding code located in RAM
89
===================================================================
90
Many possible ColdFire target processors have an external bus, so
91
you can use large external RAM devices for debugging applications
92
during development. But some processors do not have an external
93
bus, so you must accommodate applications in on-chip memory.
94
Although this on-chip RAM accommodates this CodeWarrior project,
95
it probably is too small for full development of your application.
96
Accordingly, for a processor without external bus, you should locate
97
your applications in flash memory.

//  Flashing the code
101
//------------------------------------------------------------------------
102
1. Select the appropriate project target and build it
103
2. Make sure the correct remote connection is selected in the Remote
104
   Connection debugger panel
105
3. In the CodeWarrior IDE menu, select Project > Set Default Project
106
   and select your project
107
4. In the CodeWarrior IDE menu, select Project > Set Default Target
108
   and select the project target that has the code you want to flash
109
5. In the CodeWarrior IDE menu, select Tools > Flash Programmer
110
6. Go to the flash programmer Target Configuration panel, click Load
111
   Settings
112
7. Browse to the \cfg sub folder and
113
   select the flash settings xml file matching your build target
114
8. Check that Use Custom Settings checkbox is not selected
115
9. Go to the Erase/Blank Check panel, select the All Sectors option and
116
   click Erase
117
10. Go to Program/Verify panel, click Program
118
11. Your code should now be flashed
119
 
120
//------------------------------------------------------------------------
121
// Terminal Settings
122
//------------------------------------------------------------------------
123
In case the UART is supported, the terminal should be setup with:
124
- 19200 bauds,
125
- 8 data bits,
126
- no parity,
127
- 1 stop bit,
128
- no flow control.
129
 
130
Please check this file in the project.
131
 
132
//------------------------------------------------------------------------
133
//  Getting Started
134
//------------------------------------------------------------------------
135
To build/debug your project, use the CodeWarrior IDE menu Project > Debug
136
or press F5. This will launch the debugger. Press again F5 in the
137
debugger (or the CodeWarrior IDE menu Project > Run) to start the
138
application. The CodeWarrior IDE menu Project > Break stops the
139
application.

141
//------------------------------------------------------------------------
142
//  Adding your own code
143
//------------------------------------------------------------------------
144
Once everything is working as expected, you can begin adding your own code
145
to the project. Keep in mind that we provide this as an example of how to
146
get up and running quickly with CodeWarrior. There are certainly other
147
ways to handle interrupts and set up your linker command file. Feel free
148
to modify any of the source files provided.
