... Flash Memory Organization 3.1.1 Flash Write Access AT91EB40 Evaluation Board User Guide The On-board Software The Flash memory is an AT29LV1024 (64K x 16 arbitrarily located at the address 0x01000000 by the boot software. It has been split in two different spaces: 0x01000000 up to 0x0100FFFF = boot and Angel software ...

... If neither TIOB1 nor FIQ are pressed, the amber LED is lit and Angel is activated. The FTS is a part of the boot software that allows testing of the AT91EB40 started by the boot if the FIQ button is pressed at reset. At start of the FTS, the LEDs 1, 2 and 3 light up. The user must then release the FIQ button. The LEDs switch off and then blink once ...

... When Angel starts, it recopies itself into the SRAM in order to run faster. The SRAM used by Angel is from 0x02020000 to 0x02040000, i.e., the highest half of the SRAM. The Angel on the AT91EB40 can be upgraded regardless of the version 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 ...

... B-C AT91 TIOB1 input is from TIOB1 switch The AT91EB40 is supplied with four 128K x 8 byte SRAM memories. If, however, the user needs more than 512K bytes of memory, the devices can be replaced with four 512K x 8 3.3V 15/20 ns SRAMs giving, in total, 2048K bytes. If this is done, LK1 must be moved to position B-C ...
