■
Select “Execute – Go” or press F5: the debugger stops on the main function,
displaying the C source file.
■
Select “Execute – Go” or press F5 again: the console window continuously displays
“Loop 0, Loop 1,…” and the amber and red LEDs are blinking.

Use with the
Multi-ICE Debugger
The procedure is the same as for EmbeddedICE (see “Use with Embedded ICE” on
page 3-4) except that the Multi-ICE Debugger for Windows (MDW) is used in place of
ADW. The mode is automatic with Multi-ICE; the configuration of the debugger is
useless.
3.6.6
Programming and
Executing in Flash
Open the project “led_blink.apj” in the directory “<MyFolderAT91>\Examples\ led_blink”.
Select the variant “EB01Flash”, and build the application.
Power up the AT91EB01 and establish a debugger (any one) with the target. Refer to
the sections above.
Execute the programming sequence (as described in the section “Using the Flash
Downloader” on page 3-13):
$top_of_memory=0x02200000
(
Note:
This line should not be entered if using Angel.)
load <MyFolderAT91>\Tools\FlashPgm\at91eb01\flash.li <MyFolderAT91>

The flash programmer displays the following in the Console Window :

Booting with the

3.7.1
Flash Memory
Organization
The Flash memory is an AT29LV1024 (64K x 16). It is arbitrarily located at the address
0x01000000 by the boot software (see “Programmer’s Model” on page 4-1). It has been
split in two different spaces :
■
0x01000000 up to 0x0100FFFF = boot and Angel software
■
0x01010000 up to 0x0101FFFF = application software
The switch SW1 allows the signal “SW_A16” to be set (see Schematic 3 “External Bus
Interface”) which drives the bit A15 of the flash part:
