The LPC43xx contains a shadow pointer register that * allows areas of memory to be mapped to address 0x0000 0000. The default, * reset value of the shadow pointer is 0x1040 0000 so that on reset code in * the boot ROM is always executed first. * * The boot starts after reset is released. The IRC is selected as CPU clock * and the Cortex-M4 starts the boot loader. By default the JTAG access to the * chip is disabled at reset. The boot ROM determines the boot mode based on * the OTP BOOT_SRC value or reset state pins. For flash-based parts, the part * boots from internal flash by default. Otherwse, the boot ROM copies the * image to internal SRAM at location 0x1000 0000, sets the ARM's shadow * pointer to 0x1000 0000, and jumps to that location. * * Of course, using JTAG the executable image can be also loaded directly * into and executed from SRAM. */ /* The LPC4330 on the LPC4330-Xplorer has the following memory resources: * * 1. 4096Kb of SPIFI FLASH beginning at address 0x1400:0000 * 2. 264KB of total SRAM: * a. 128KB of SRAM in the CPU block beginning at address 0x1000:0000 * b. 72KB beginning at address 0x1008:0000 and * c. 64KB of AHB SRAM in three banks beginning at addresses 0x2000:0000, * 0x2000:8000 and 0x2000:C000. * 3. No internal FLASH * * Here we assume that: * * 1. We will be running out of SPIFI flash at 0x1400:0000, and * 2.
