AT91EB40A Evaluation Board User Guide
The AT91EB40A
Evaluation Board
Boot Software
Program
The AT91EB40A Evaluation Board embeds an AT49BV1604 or AT49BV1614 Flash
memory device programmed with default software.
When delivered, the Flash memory device contains:
! the Boot Software Program
! the Functional Test Software (FTS)
! the Flash uploader
! the Angel Debug Monitor
! a default user boot with a default application (LED Swing Application)
The boot software program, functional test software (FTS), and the Flash downloader
are in sectors 0 and 1 of the Flash device. Sectors 3 to 8 support the Angel Debug Mon-
itor. The default user boot with a default application is located in sector 24.
These sectors are not locked in order to provide an easy on-board upgrade. The user
must avoid overwriting these sectors. The remaining sectors are user definable, and can
be programmed using one of the Flash downloader "Flash_16x4" solutions offered in
the AT91 library. See “Appendix D – Flash Memory Mapping” on page 8-1 for further
details.
The boot software program configures the AT91R40008, and thus controls the memory
and other board components.
The boot software program is started at reset if JP1 is in the STD position. If JP1 is in
the USER position, the AT91R40008 boots from address 0x01100000 in the Flash,
which must have a user-defined boot.
The boot software program first initializes the EBI, then executes the REMAP procedure
and, finally, checks the state of the buttons as described below.
! When the SW1 button is pressed:
! The SW2 button is reserved.
All the LEDs light up together.
The D1 LED remains lit when SW1 is released.
The Functional Test Software (FTS) is started.
