I followed this (excellent) video on using the USB Descriptor Tool while running CCS 6 on my 64-bit Win7 system. The video finally got to the point where I was instructed to click on the little gear icon, then be treated to an automatic modification of my (open) main.c file in CCS. It did not happen: instead I was asked (by the tool) where to save the resulting (.c and .h) files. i still have little clue on how to integrate these files. How can I get this to work like that video said it would?

Forum Post: RE: CCS: Constants Manually Placed in Flash Are Not Initialized
Sorry, I should have mentioned that I tried both adding a reference and adding "#pragma RETAIN" already. Here is the updated code:
#include <stdint.h> #pragma DATA_SECTION(".infoD") #pragma RETAIN uint16_t test = 0x1234; int main() { while (1) { uint16_t dummy = test; dummy++; } } Notice that I had to remove the "const" keyword, otherwise the compiler would remove the access to the memory location and insert 0x1234 directly into the assembly. While debugging I can change the value at memory location .infoD (0x1800) and see it reflected in dummy; however memory location 0x1800 has a value of 0xFFFF when the firmware is first flashed and the debugger breaks at main().
My overall goal is to be able to initialize particular flash addresses to constant values; however I can't find a combination of keywords which will accomplish that correctly.

Forum Post: RE: Dynamic linking library for C665x
Hello Todd,
Thank you for your information. I'm now able to see the assembly code accessed global variable using GOT by adding --pic and --linux. Then out file is created. My option and linker file are below.
compiler and linker option:
-mv6600 --abi=eabi -k --pic=near --linux -z --dynamic=lib
linker file:
MEMORY
{
BLOB: o = 0h l = 10000000h
}
SECTIONS
{
.startFunc : 0x0
.startData : BLOB
.dsbt : BLOB
}
But other problem occur. I run bat file below after building out file to create binary file. The binary is read to appropriate address by main application using fread.
test.bat:
set CCS_INSTALL_ROOT=C:/ti/ccsv5
set CG_TOOL_ROOT=%CCS_INSTALL_ROOT%/tools/compiler/c6000_7.4.7
del dllAdd.dll
"%CG_TOOL_ROOT%/bin/strip6x" -o dllAdd.dll dllAdd.out
"%CCS_INSTALL_ROOT%/utils/tiobj2bin/tiobj2bin.bat" dllAdd.dll dllAdd.bin "%CG_TOOL_ROOT%/bin/ofd6x.exe" "%CG_TOOL_ROOT%/bin/hex6x.exe" "%CCS_INSTALL_ROOT%\utils\tiobj2bin\mkhex4bin.exe"
error message:
"strip6x" -o dllAdd.dll dllAdd.out
error: corrupted object file: program segment contains a section whose vaddr
(0x0000022f) is less than the program segments (0x00000240)
error: corrupted object file: a single dynamic relocation table was requested,
but the DT_JMPREL relocation table was not placed immediately after the
DT_RELA table in memory and/or the section table; the .dynamic section
Could you possibly give me advice?

Kazu

Forum Post: RE: Dynamic linking library for C665x
Hello Kazu,
In a dynamic linking scenario, you should not be using a linker command file. Target memory allocation and symbol resolution (for symbols in the .dll that is being loaded) and relocation of references to imported symbols must be resolved at load time by the dynamic loader application. There should be no reason for you to use a linker command file in creating the .dll. The code and data will be organized by the linker according to a dynamic linking segment model (please see the above referenced "C6000 Embedded Application Binary Interface" specification for more details). In general, you should see all code sections collected into a Read-Only program segment, and data sections collected into a Read-Write program segment. The R/W program segment will normally contain all data objects that are referenced via near-DP addressing at the front of the segment.
It is unclear to me what your intention is from looking at the contents of the .bat file. Can you provide a more general description of what it is you are trying to accomplish?
Regards,
Todd Snider

Where specifically did you put the v5 files as far as in the v6 directory? Also, did you copy any other ones? I can't get it to work and I am using the same board as you

Forum Post: RE: Why the TI Wiki code to enable Neon crashes?
Rafael,
I looked this forum thread. But still have more questions:
Do I need to include a boot.asm file into my project as one regular file to compile with other files in my project? The boot.asm I found is in TI CCS folder "C:\ti\xdctools_3_25_03_72\packages\ti\targets\arm\rtsasm\boot.asm.
Inside the file there are some lines of code to enable Neon and set to system-Mode. Should I bring this one in my project and compile it with my other project files?
Thank you,

Hi,
Thanks for alerting us to this problem. The LP38513-ADJ dropout voltage was set a little too conservatively in the WEBENCH Power Designer, limiting the load current for your design. It's adjusted now. Please try your design again.

Forum Post: ndk_2_21 and bios_mcsdk_02_01_02_06_setupwin32
When installing bios_mcsdk_02_01_02_06_setupwin32, component ndk_2_21 can be detected but can't not be installed in CCSV5.5. Therefore, ndk_2_23_02_03 is downloaded, unzipped, and copied into the folder where ndk_2_21 is installed by bios_mcsdk_02_01_02_06_setupwin32. However, ndk_2_23_02_03 can't be detected automatically by CCSV5 in some situations. Is there a way to make CCSV5.5 detect and install ndk_2_23_02_03?
