Section 3
The On-board Software
3.1
AT91EB55
The AT91EB55 Evaluation Board contains an AT49BV162A Flash device programmed
Evaluation Board with default software. Only the lowest eight 8-Kbyte sectors are used. The remaining
sectors are user-definable and can be programmed using one of the Flash downloader
solutions offered in the AT91 library.
When delivered, the Flash device contains:
! The Boot Software Program
! The Functional Test Software
! The Angel Debug Monitor
! A Default User Boot with a Default Application
The boot and FTS and are in sectors 0 and 1 of the Flash. These sectors are not locked
for an easy on-board upgrade. The user must avoid overwriting this sector.
3.2
The Boot
Software
Program
The Boot Software Program configures the AT91M55800A and thus controls the mem-
ory and other board devices.
The Boot Software Program is started at reset if JP1 is in the STD position. If JP1 is in
the USER position, the AT91M55800A boots from address 0x01010000 in the Flash,
which must have a user-defined boot.
The Boot Software Program first initializes the master clock frequency at 32 MHz, the
EBI, then executes the REMAP and checks the state of the buttons as described below.
As long as the SW1 button is pressed:
! All the LEDs light together
! The D1 LED remains lit until SW1 is released
! The Functional Test Software (FTS) is started
When the SW2 button is pressed:
! Reserved
! When the SW4 button is pressed:
! The shutdown function from AT91M55800A is activated. The power-up can be
achieved by pressing the S1 push button only (Wake-up function)
