LPC1788 and LPC4088 Embedded Artists Development Kit System Init code

Detailed Description

The System initialization code is called prior to the application and initializes the board for run-time operation. Board initialization for the EA1788/EA4088 boards includes clock setup, default pin muxing, and memory configuration.

With the exception of stack space, no RW memory is used for this call.

LPC1788 and LPC4088 EA board setup
Clocking:
CPU setup for 120MHz off main oscillator and PLL0, EMC setup for 60MHz USB setup for 48MHz of main oscillator and PLL1 Peripheral clock rate set to 60Mhz SPIFI clock disabled Pin muxing:
Sets up various pin mux functions for the board (Ethernet, LEDs, etc.)
Sets up the external memory controller signals
Memory:
Sets up DRAM.

)

Setup the system.

Returns

none

Note

SystemInit() is called prior to the application and sets up system clocking, memory, and any resources needed prior to the application starting.
