|

* -----------------------
|
||||
*
|
||||
* The ARM core starts executing code on reset with the program counter set
|
||||
* to 0x0000:0000. 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.
|
||||
*
|
||||
* However, using JTAG the executable image can be also loaded directly into
|
||||
* and executed from SRAM.
