a c6720 emulation probluem ,just like peter`s - liqu...@163.com - Sep 5 15:47:57 2008
hello moto~~
a joke first~:)
i got the same problem with the c6720 emulation operation just like what peter described.the
run button works,but the code just can`t load into the target curretly.here`s the asm code
displayed in the asm window after the EMULATOR set connected in the ccs.the first line is where
the green arrow pointed to.
→00001DDC 00008000 NOP 5

HERE is the asm code displayed in the asm window after the program loaded..
there are 4 green arrows point from the second line to the fifth line like

i tried to set the PC to the main func and press the run button,it works and stopped at the
for() func.
i really dont know whats happend to it cus am a new in c6x dsp chip.
i`v read some docs about the c6000 pin setting,and don`t sure if the
c672x needs pin setting,but the datasheets never claim that it does.
it getting me a crazy.
i wish sombdoy could help me to handle this,and many thanks.

The above are internal ROM addresses that are executed when the chip comes up.

This is not good. The instruction packet at 100079A0 does not appear
to be correct for the c672x according to the disassembler.
A. The code was either incorrectly generated [the 64plus/davinci
processor type was used although if that were the case, I would expect
the the file not to load]
or
B. The code was loaded incorrectly by the emulator.
Q1. Check the project build options to verify that the correct
processor type was used to build your '.out' file. What option did you
use??
Q2. Disassemble your '.out' file and locate 'c_int00:'. Is it the same
as the info above??
How to disassemble an out file.
1. Open a 'DOS prompt' in the directory containing the out file.
2. Append the path to the disassembler to your path [I use
'set path=C:\CCStudio_v3.3\C6000\cgtools\bin;%path%
for CCS 3.3
3. enter 'dis6x myfile.out > myfile.out.txt'' on the command line.
4. open 'myfile.out.txt' in a text editor and find 'c_int00' to
compare with your output above.
Q3. Do the 2 disassemblies match?? [the text may differ slightly]

Re: a c6720 emulation probluem ,just like peter`s - Peter Wu - Sep 6 7:40:17 2008
HIHI
Glad to know that my posts are able to help some one else.
Let's assume that there is no hardware problem on ur target board and the
connection between the emulator and target board is well established.
What type of emulator do u used?
CCS version?
Can u see and modify the internal registers?
Have u setup the GEL file for EMIF and PLL?
Best regards
Peter Wu

thank you so much. the problem has been solved. I made a phone call to WINTECH,
they told me that I should copy the tixds672x.drv file under the CCS3.1 `s driver path to
cover the the same file under the ccs3.3 ...I found that
there is no such file there in the 3.3,,,so I just copy the file to the floder,run ccs,but
nothing happend.it was the same situation,the code is still wrong.so I format the
disk,reinstall the win system,made it clear.
and,install the CCSv3.1,drive the emulator,update the ccs31 program,run again the code,it
works. the c code works the same as it is in ASM.
although the problem has been solved, but i still can`t find out why this could be.
and now i would like to thank mike and peter `s help. i can`t

<mld>
Congratulations on resolving the problem!! and thanks for the feedback.
I cannot tell what the problem is since I do not use a WinTech
emulator. If I understand your experience, you say that the WinTech
did not work with the CCS 3.3 driver but it did work with the CCS 3.1
tixds672x.drv.

yes ,mike. that`s what i mean.the emulator dont work with the ccsV3.3,it just could read the silicon data,chang the data in the registor,but seems readback the wrond one.. and,i think the problem seems like,the program just can jump the right address,so it can`t load currectly. ------------------------------------ OMAP35x EVM jump-starts low-power apps ------------------------------------ The modular and extensible OMAP35x Evaluation Module (EVM) enables developers to start building applications based on the OMAP35x architecture:http://www.DSPRelated.com/omap35x

HIHI liqunchao Sorry reply so late. Glad to hear that the problem is solved. I think this issue happens to a lot of people who use the non-SpectrumDigit emulator. Replace the drive seems to be the only way to fix it.

Re: Re: a c6720 emulation probluem ,just like peter`s - Richard Williams - Sep 13 8:01:52 2008
liqunch,
The display after the asm is loaded is not code.
and before the code is loaded, the ram is always going to contain trash.
My first thought is the linker has produced trash.
How are you loading the code?
