AT91EB40A Evaluation Board User Guide
Testing the
AT91EB40A
Evaluation Board
To test the AT91EB40A Evaluation Board, perform the following procedure:
1. Hold down the SW1 button and power-up the board, or generate a reset and wait
2. Release the SW1 button. The LEDs D1 to D5 light up in sequential order. If all
The LEDs represent the following test functions:
! D1 for the internal SRAM
! D2 for the external SRAM
! D3 for the external Flash
! D5 for the USART
! D6 reserved
! D7 reserved
! D8 reserved
During a complete test cycle, each LED flashes once to inform the user that the corre-
sponding function has been successfully tested. If an error is detected, all the LEDs will
light up twice. After a complete test cycle, the embedded self-test software called FTS
(Functional Test Software) restarts a new cycle.
Note:
for the light sequence on each LED to complete. All the LEDs light.
the LEDs light up twice, this indicates an error. Note that LEDs D6 to D8 are
reserved for future use.
1. At factory, no external SRAM is mounted on the board. The test shows an error. If the
user upgrades the board with external SRAM, the test runs normally.
