hi all:
       I meet a strange problem on 510usb emulator.
       Environment: (1)DSP C6727B, (2)CCS v3.3 , (3)emulator: 510usb
emulator.(4) program are all located in internal RAM
       I write a test project in ASM. After the compiling and linking, the
output file can be downloaded to DSP(C6727B), and it runs well. 
       But when I write a test project in C, after the compiling and linking,
the output file can't be downloaded to DSP completely, and it can't run!
Typically, only the first 4-bytes can be downloaded to DSP by JTAG, and the
other code are missing!! They are not downloaded to the corresponding address in
DSP.
       I can't understand it. I checked the project in C carefully, especiall
all the build options, and I think I don't make a mistake. 
       I am doubt that whether the driver of 510 emulator is not correct? or
there are some mistakes I make which I don't know?
       Are there someone meet the same problem? Or someone can give me some
suggestion to solve it? THANKS!

Have you verified that all addresses are fir internal memory??

Michael Dunn:
       Thanks for your help!
       Problems have been solved. There is a bug in CCS3.3 . The emulator
provider helps me to replace some files and then all works well now.
       Thanks!

I use the ofd6x to analysis .out file. It displays all the section information
and symble table,some like the information gived by .map file. But I can't find
a obviously mistake. 
I compare the two analysis results of ASM and C project. I think the results are
similar and right, or maybe I don't know which is wrong.

  Have you verified that all addresses are fir internal memory??
  0x10000000 - 0x1003FFFF.

The XDS510 has no idea about how the '.out' file was generated. Your
probably have a problem with your C project linker command file. If
you do notsee the problem, you can run 'ofd6x yourOutFileName' from a 
DOS prompt in the directory that contains the out file. [you will need
a path to 'C:\<CCStudio_Install_Dir>\C6000\cgtools\bin']. This will
analyze your '.out' file.

The XDS510 has no idea about how the '.out' file was generated. Your
probably have a problem with your C project linker command file. If
you do notsee the problem, you can run 'ofd6x yourOutFileName' from a
DOS prompt in the directory that contains the out file. [you will need
a path to 'C:\<CCStudio_Install_Dir>\C6000\cgtools\bin']. This will
analyze your '.out' file.
