Setting Up the AT91SAM7L-STK Board
2-2 AT91SAM7L-STK Rev. B Starter Kit User Guide
6414A–ATARM–12-Sep-08
2.4.0.2 DBGU Interface
AT91SAM7L series Flash Microcontroller is able to boot from internal ROM or internal Flash memory
through a general purpose NVM (GPNVM1) bit. When this bit is cleared, the MCU will boot from internal
ROM to enable the SAM-BA connection through DBUG.
Connect AT91SAM7L-STK DBGU port (J4) to PC COM port through an RS232 cable. Then you can run
the SAM-BA from the PC to program the internal Flash of the MCU as well as the GPNVM1 bit.
