|

* 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. 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.
|
||||

|
||||
|

/* The LPC4357 on the LPC4357-EVB has the following memory resources:
|
||||
*
|
||||
* SRAM:
|
||||
* a. 32kB of SRAM mapped at 0x10000000
|
||||
* b. 40kB of SRAM mapped at 0x10080000
|
||||
* Internal flash:
|

* a. 512kB of flash (bank A) at 0x1a000000
|

* b. 512kB of flash (bank B) at 0x1b000000

* External flash:

* a. 4MB of SPIFl flash at 0x14000000

* Here we assume that:
|
||||
*
|
||||
* 1. We will be running out of SRAM at 0x1000:0000, and
|
||||
* 2. All .data and .bss will all fit into the 72KB SRAM block.
|
||||
*
|
||||
* NOTE: That initialized data is kept in the program memory SRAM and copied
|

|
||||
* 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.
