/* ======================================================
// For Code Composer Studio V2.2 and later
// ---------------------------------------
// In addition to this memory linker command file,
// add the header linker command file directly to the project.
// The header linker command file is required to link the
// peripheral structures to the proper locations within
// the memory map.
//
// The header linker files are found in <base>\DSP281x_Headers\cmd
//
// For BIOS applications add: DSP281x_Headers_nonBIOS.cmd
// For nonBIOS applications add: DSP281x_Headers_nonBIOS.cmd

/* Define the memory block start/length for the F2812
PAGE 0 will be used to organize program sections
PAGE 1 will be used to organize data sections
Notes:
Memory blocks on F2812 are uniform (ie same
physical memory) in both PAGE 0 and PAGE 1.
That is the same memory region should not be
defined for both PAGE 0 and PAGE 1.
Doing so will result in corruption of program
and/or data.
