/* The AT91SAM3U-4 has 256Kb of FLASH beginning at address 0x0008:0000,
|
|
* 32Kb of SRAM beginning at address 0x2000:0000, and 16Kb of SRAM beginning
|
|
* at address 0x2008:000 (used only for heap). When booting from FLASH,
|
|
* FLASH memory is aliased to address 0x0000:0000 where the code expects to
|
|
* begin execution by jumping to the entry point in the 0x0800:0000 address
|
|
* range.
|
|
*
|
|
* For MPU support, the kernel-mode NuttX section is assumed to be 64Kb of
|
|
* FLASH and 4Kb of SRAM. That, of course, can be optimized as needed (See
|
|
* also configs/sam3u-ek/kernel/kernel.ld.
