This a simple bootloader for AT91SAM7{S,X}{64,128,256} processors. It
permits you to download new code to the device over USB. This bootrom is
installed at address 0x00000000 in the ARM, which means that it is the
first piece of code to execute after reset. At startup, it waits for
a few seconds to see if the downloader is trying to connect. If not,
then the bootloader gives up control and jumps to your program. If the
downloader is trying to connect, then the bootloader receives the new
program over USB and writes it into flash.
This example project shows how to use the IAR Embedded Workbench for ARM
to develop code for the IAR-STM32-SK evaluation board. It shows
basic use of I/O, timer and the interrupt controllers.
Displays running lights on the board LED s.

DESCRIPTION
===========
This example project shows how to use the IAR Embedded Workbench for ARM
to develop code for the Atmel AT91SAM9261 evaluation boards.
It shows basic use of parallel I/O, timer and the interrupt controller.
It starts by showing different patterns on the LED s separated by half second.
COMPATIBILITY
=============
The project is compatible with the AT91SAM9261-EK board.
調(diào)試通道例子。DCC is available on ARM cores which contain EmbeddedICE logic, e.g. ARM7TDMI,
ARM9TDMI, etc. DCC is accessed by the target via coprocessor 14 using the
ARM instructions MCR and MRC.
The two assembler source files provided are:
outchan.s for Target to debugger communication
inchan.s for Debugger to target communication
