loading example program on F28335

Hello everybody,

I am new to this community and F28335 controllers.
I am working with the F28335 and connect through a Jtag Emulator USB2.0 

I am currently following the tutorial "Developing a simple Program".
When I tried to load the program I got the error Message "data verification failed at 0x3fffc0"
According to the suggestions in this board I modified my linker command file by adding "type=DSECT"
to the sections reset and vectors. Here my volume.cmd file

-stack 400

-heap 400
MEMORY
{
   PAGE 0 : PROG(R)     : origin = 0x3E8000, length = 0x10000
   PAGE 0 : BOOT(R)     : origin = 0x3FF000, length = 0xFC0  
   PAGE 0 : RESET(R)    : origin = 0x3FFFC0, length = 0x2
   PAGE 0 : VECTORS(R)  : origin = 0x3FFFC2, length = 0x3E

   PAGE 1 : M0RAM(RW)   : origin = 0x000000, length = 0x400
   PAGE 1 : M1RAM(RW)   : origin = 0x000400, length = 0x400
   PAGE 1 : L0L1RAM(RW) : origin = 0x008000, length = 0x2000
   PAGE 1 : H0RAM(RW)   : origin = 0x3F8000, length = 0x2000
}
 
SECTIONS
{
   /* 22-bit program sections */
   .reset   : > RESET,   PAGE = 0, type=DSECT
   .vectors : > VECTORS, PAGE = 0, type=DSECT
   .pinit   : > PROG,    PAGE = 0
   .cinit   : > PROG,    PAGE = 0
   .text    : > PROG,    PAGE = 0

   /* 16-Bit data sections */
   .const   : > L0L1RAM, PAGE = 1
   .bss     : > L0L1RAM, PAGE = 1
   .stack   : > M1RAM, PAGE = 1
   .sysmem  : > M0RAM, PAGE = 1
   .cio     : > M0RAM, PAGE = 1

   /* 32-bit data sections */
   .ebss    : > H0RAM, PAGE = 1
   .econst  : > H0RAM, PAGE = 1
   .esysmem : > H0RAM, PAGE = 1
}

After this modification I was able to load volume.out onto the chip.
During that I get the following notifications

GEL Output:
XINTF x16 enabled by GEL
ADC Calibration complete
ADC Calibration complete

Messages:
Loader: One or more sections of your program falls into a memory region that is not writable.  These regions will not actually be written to the target.  Check your linker configuration and/or memory map.

The problem is that the Disassembly window is blank. Containing only lines like that "---------- ------ ----"

If I click GoMain in the Debug Menu it tells me "Could not set breakpoint for GEL_Go()

can anybody tell me what is the problem here?

Regards
