    The procedure is as follows: 1. Connect the Serial A (or B ) port of the AT91EB40A Evaluation Board to a host PC Serial Port using the straight serial cable provided. 2. Start the AT91Loader.exe program available in the AT91 Library on the host com- puter.

  • Page 15: Angel Monitor

    SRAM used by Angel is from 0x00020000 to 0x0003FFFF, i.e., the highest half part of the internal SRAM. The Angel on the AT91EB40A Evaluation Board can be upgraded regardless of the ver- sion programmed on it. Note that if the debugger is started through ICE while the Angel monitor is on, the Advanced Interrupt Controller (AIC) and the USART channel are enabled.
