MOTOROLA Bootloader 1-1

Chapter 1

Bootloader

1.1 Serial Bootloader

The Serial Bootloader has been developed to load and run a proprietary user application presented
as an S-Record file into the Program and Data memory. The Serial Bootloader is located in the
dedicated Program Memory region, called Boot Flash (See Section 1.1.3). The Serial Bootloader
supports the simplest serial protocol, so any standard serial terminal program can be used on the
host PC.

The Serial Bootloader application reads the S-Record file of a user application (for example,
generated by CodeWarrior) via serial interface, parses this S-Record file, and stores needed data
in Program and Data Flash memory. When the processing of the S-Record file is finished, the
Bootloader launches the loaded application. If any error occurs while loading the S-Record file,
the Bootloader outputs an error message with an error number via the serial line and resets the
processor. See Figure 1-1.

1.1.3 Target Consideration

1.1.3.1 56F801

When the TargetDirectives file contains #define DSP56801EVM, this application is built
assuming the existence of an internal relaxation oscillator and corresponding calibration value. At
run-time, the application automatically calibra tes the internal relaxation osc illator to run at 8MHz.

Note: For the 56F801, only processors with a date code GREATER THAN 0152 marke d in

the lower right corner of the part contain the internal oscillator calibration value. For
parts built prior to this date, the TargetDirectives file should contain the following for
correct operation:

#define DSP56801EVM
#define PLL_USE_EXTERNAL_OSC

Note: The 56F802 does NOT have an external oscillator and must therefore have the

following in the TargetDirectives file for correct operation:

#define DSP56801EVM

1.1.3.2 56F827

1.1.3.2.1 56F827 Boot Flash

The 56F827 has 63KB of on-chip Program Flash memory and 1KB of on-chip Program RAM.
Unlike the 56F826, which has dedicated Boot Flash hardware, the 56F827 has no dedicated Boot
Flash hardware. As shown in Figure 1-3, Boot Flash is carved from Program Flash 2 and Program
Flash 1. The Bootloader is mapped to Program Flash 2 at location 0xF800 to 0xFFFF.

1.1.3.2.2 56F827 Hardware Reset and COP

The hardware and COP reset vectors are mapped to Program Flash 1 at locations 0x0000 and
0x0002. Unlike the 56F826, which has dedicated Boot Flash hardware, the 56F827 hardware and
COP reset vectors can be erased when programming the first page in Program Flash 1 through the
Bootloader. This can occur if power to the 56F827 is lost when the Bootloader is saving and
erasing the page that contains the reset and COP vectors. If this happens, the Bootloader will not
be available on the next 56F827 reset.

Figure 1-3. 56F827 Boot Memory

1.1.3.2.3 56F827 Bootloader Operation

The Bootloader program code which permits programming both Program Flash1 and Program
Flash 2 resides in a Boot Flash section which is part of Program Flash 2. In order to write or erase
part of Program Flash 2, the Bootloader functions that permit programming Flash 2 are relocated
at run time and are executed from Program RAM. This allows the ability to program both
Program Flash 1 and Program Flash 2 with user application code. Every time the 56F827 power is
recycled or reset, the Serial Bootloader resident in the Boot Flash will re-copy Flash programming
functions from the Boot Section to Program RAM. Figure 1-4 demonstrates how the Bootloader
program code (which is configured for internal memory operation) will be mapped into physical
memory on the 56F827 target using CodeWarrior tools.

Bootloader

1.1.4.2 Host Terminal Program Set-up

A host terminal program is used to communicate with Bootloader. The terminal must be
configured to the following mode:

The following description assumes that Microsoft Windows HyperTerminal program is used. To
configure Microsoft HyperTerminal to communicate with Bootloader, the PC user should start
HyperTerminal and create a new connection. Select the COM port connected to the EVM board
and set:

The HyperTerminal can now display Bootloader messages.

1.1.5 Execute

To execute the Serial Bootloader application after loading it into Flash, set jumpers as described
in Section 1.1.2.1 and push the RESET button.

If the terminal program is properly set up and the EVM and the Host PC are properly connected,
the terminal program will display a Bootloader start-up message:

"(c) 2000-2001 Motorola Inc. S-Record loader. Ver sion 1.1"

To load the S-Record file, select the Transfer/Send text file from the HyperTerminal menu and
select a file. When the S-Record file is loaded and the application is started, the terminal windows
displays a message similar to this:

"(c) 2000-2001 Motorola Inc. S-Record loader. Ver sion 1.1
Loaded 0x044d Program and 0x 000a Data words.

Application started."

The download rate is about 7660 bytes of S-Record file per second loaded from the terminal or
about 1740 words of program or data memory stored into Flash per second.

If an error is detected while loading the S-Record file, the Bootloader displays the error message
and resets the processor. For example, if an S-record file contains a character that is not permitted
for S-Records, the following message is displayed:

"(c) 2000-2001 Motorola Inc. S-Record loader. Ver sion 1.1
Error # 0002

MOTOROLA Bootloader 1-9

After this message, the Bootloader resets the processor and waits for the S-Record file again.
Other loading errors are described in

Table 1-1.

If an application previously loaded via the Bootloader uses the variable
BSP_BOOTLOADER_DELAY, (see

Section 1.1.6), the Bootloader waits for the S-Record file

only until the required time-out expires, then launches the application. When this happens, the
terminal window contains a message similar to this:

"(c) 2000-2001 Motorola Inc. S-Record loader. Ver sion 1.1
Application started."

1.1.6 Requirements for a Loaded Program

If the application is loaded via the Bootloader, it must meet the following requirements:

• Particular start address for appli cation - The entry point for the loaded application must
be located at address 0x0080 in Program memory; i.e., immediately after the interrupt table

1-10 56F8xx: Serial Bootloader User Manual MOTOROLA

Bootloader

• Application COP vector - To use COP interrupt vector in an application loaded via
Bootloader, the entry point for the COP ISR must be located at address 0x0082 in Program
memory

• Application start delay variable must be set at address 0x0085 in Program Flash

• Restricted resources use - The application cannot occupy Reset and COP interrupt
vectors, and cannot place code into Boot Flash memory area. There is no way to place any
initialized variable from the application into internal data RAM while loading. This
memory area is used by Bootloader. All data from the S-Record file that address to the
restricted area will be ignored. External Program memory is unavailable while loading the
application because the Bootloader is performed in DSP Mode 0A memory map.

The Bootloader provides a configuration variable (BSP_BOOTLOADER_DELAY) can be
defined in the Bootloader’s appconfig.h file that determines the application’s start delay time-out.

Possible values of BSP_BOOTLOADER_DELAY:

If there is no BSP_BOOTLOADER_DELAY set in the appconfig.h file, the default value for
time-out is 30 seconds.

1.1.7 S-Record Generation

Figure 1-5 illustrates how a user’s application within Cod e Wa rr ior can be set up to generate an S-Reco rd

needed by the Bootloaders to program the user’s application into the 56F8xx device’s Flash.

0 Disable the Bootloader, start the application

immediately. After loading the application with this
setting, there are only two ways to re-enter Bootloader:

• Reload the Bootloader from Metrowerks
CodeWarrior into Boot Flash

• Reprogram the value of the start delay variable
located at address 0x0083 in the Program Flash
to zero value (0x0000) in the loaded application

0 - 254

Set waiting time for the start of the S-Record file for
0-255 seconds before the start of a previously-loaded

MOTOROLA Bootloader 1-11

Figure 1-5. S-Record Settings in the User Application’s Project Settings

“Max Record Length” and “EOL Character” are set to the default values shown in Figure 1-5. “Max
Record Length” can be mod ified to up to 252. “EOL Chara cter” can c hang ed to “Mac” or “UNIX” with no
effect.

1.1.8 Peripheral Usage

If the hybrid controller is used in a single chip mode, the Bootloader uses only internal Data RAM
for data buffering.

The Bootloader does not initialize any device peripheral except SCI0, Port E and PLL. The PLL
multiplier is set to18, which equals the hybrid controller’s operational frequency of 72MHz.
Before starting the application, SCI0 is disabled, but the PLL is not reprogrammed to its initial
state.

The Bootloader uses a statically-calculated SCI baud rate value. This value was calculated with
the assumption that the external Oscillator Frequency is 8MHz.
