The System initialization code is called prior to the application and initializes the board for run-time operation. Board initialization for the Hitex EVA boards includes clock setup, default pin muxing, and memory configuration.
With the exception of stack space, no RW memory is used for this call.
LPC1850 and LPC4350 Hitex EVA setup
Clocking:
All base clocks enabled by default (Save power by disabling un-needed clocks)
CPU PLL set to maximum clock frequency (as defined by MAX_CLOCK_FREQ value)
SPIFI FLASH clock setup for fastest speed
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, static RAM, and NOR FLASH.
