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
Eduard
