AT91SAM ARM
For users of the Atmel AT91SAM7 and AT91SAM9 ARM CPU chips. Atmel has taken a new direction by combining on chip flash and ram with the ARM CPU on a single die. This provides low cost devices for small systems using the ARM CPU. This group is to exchange information to help users get started and learn how to use the devices.

Hi all,
I wanna use the 64K internal SRAM of AT91SAM9RL64 as 32K I-TCM and 32
D-TCM.
But I don't get it quite much. I am loading my boot code at the
beginning from flash to t...
