Self-Test
Board Recovery
A software test package is available to implement a functional test for each section of the board. Refer to
the SAM4S-EK2 page on www.atmel.com.
Closing JP3 and powering the board will assert ERASE and clear GPNVM bit 1, and thereby select the
boot from the ROM by default. The MCU will boot from the internal ROM to enable a SAM-BA connection
through the UART. Connect the SAM4S-EK2 UART port (J3) to a PC COM port through a RS232 cross-
over cable.
You can then run the SAM-BA application from that PC to program the internal Flash of the MCU as well
as the GPNVM bit 1.
