[Skyeye-developer] [ Repository Update] LPC is supported now.

[Joel Sherrill]

Ray... I cc'ed you since this is close and you wrote this BSP.

The RTEMS BSP looks close to working but the it is looping
infinitely waiting for the PLLSTAT to change during
initialization:


167         while((PLLSTAT & (1 << 10)) == 0);

Cutting and pasting the code executed from within gdb:

    PINSEL2 =0x0f814914;
    BCFG0 = 0x1000ffef;
    BCFG1 = 0x1000ffef;

    MEMMAP = 0x2;  //debug and excute outside chip

    PLLCON = 1;
#if (Fpclk / (Fcclk / 4)) == 1
    VPBDIV = 0;
#endif
#if (Fcco / Fcclk) == 4
    PLLCFG = ((Fcclk / Fosc) - 1) | (1 << 5);
#endif
    PLLFEED = 0xaa;
    PLLFEED = 0x55;
    while((PLLSTAT & (1 << 10)) == 0);
 
According the the README in the BSP, this worked with a board
that is compatible with an Olimex board.

" The board used to develop the BSP is compatible with
LPC-E2214/LPC-E2294 boards from http://www.olimex.com. The board has
a 512K SRAM (256K used to store the .text for debugging purposes)
and two serial ports."
