Other Parts Discussed in Thread: CCSTUDIO

 I  want  to  creat    a c2812  Simulator   project  on   ccs  v3.3 ,but   i  don't  know  what  i did  is right ?   it's   my   step  for  creat it . 

first   : Setup CCStudio v3.3    I  choose  F2812 Device  Simulator  and  save  it .  then  open  ccs v3.3  and  build  a  project .

while  build   ok , and  I   can't   load-program   for  a  not  correct  access  memory,  so   i   modify   the  memory-map  for  the  sim2812.gel  function  memory-map to  fit   it .  and   rebuild   it  ok,   but   it's  still   can't   load-program  for  write  a  not access  memory  .  so  i   want   ask   the  how  can  sim2812.gel  executed  after  i modify  it ?       

is  it  not   exectued   the function  "OnTargetConnect()"   of   sim2812.gel   while   can't  connect  target ? 

but    the   debug    options   for   "connect "  is   "disconnect"   .     

can  you  help  me ?  thanks .

    Hello,

    It sounds like you are not using a linker command file. Instead of modifying the gel file (which you should not do), use a linker command file.

    If you don't know what a linker command file is, I suggest you read this article:

    You can try the default F2812 cmd file that gets generated in CCSv6 that I attached here:

    [hello.c] "C:\CCStudio_v3.3\C2000\cgtools\bin\cl2000" -g -fr"C:/CCStudio_v3.3/MyProjects/new_test/new_test/Debug" -d"_DEBUG" -d"LARGE_MODEL" -ml -v28 -@"../../new_test/new_test/Debug.lkf" "hello.c"

    I remove the printf() and build ok. but when I load-program and debug it , it appear some error like it. this is why? and what should modify? thanks to tell me.

    Most likely you are missing the run-time library. You would need to add it to get printf support

    Try this attached file instead:

    I use the F2812.cmd and build . [Linking...] "C:\CCStudio_v3.3\C2000\cgtools\bin\cl2000" -@"Debug.lkf"
    I use F2812.cmd and build .

    <Linking>

    >> warning: entry point symbol _c_int00 undefined

    Build Complete,

    and I load-program the test.out , appear some follows but not disassembly, this is why and i can't entry point symbol _c_int00 ?

    I have solve the problem for debug it .
    for warning: load address of uninitialized section ramfuncs ignored .
    I modify the F2812.cmd
    ramfuncs : LOAD = FLASHD,
    RUN = RAML0,
    LOAD_START(_RamfuncsLoadStart),
    LOAD_END(_RamfuncsLoadEnd),
    RUN_START(_RamfuncsRunStart),
    PAGE = 0
    to
    ramfuncs : > RAMH0 PAGE = 1

    for warning: entry point symbol _c_int00 undefined .
    I add the rts2800.lib file and debug it ok .

    thanks for your help with patience .
