|
|
|
* Power-Up Reset Overview
|
|
|
|
* -----------------------
|
|
|
|
*
|
|
|
|
* 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. Otherwise, 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.
