... The boot program starts button is pressed. When Angel starts, it recopies itself in SRAM in order to run faster. The SRAM used by Angel is from 0x02020000 to 0x0203FFFF, i.e., the highest half part of the SRAM. The Angel on the AT91EB55 can be upgraded regardless of the version programmed on it. Note: If the debugger is started through ICE while the Angel monitor is on, the Advanced Interrupt Controller (AIC) and the USART channel are enabled ...
