Hello,
I am using a TMS570LS1224 board and CCS version 7.
I am trying to run a simple program that doesn't do anything on the board in debug mode. The code compiles and runs, but I'm noticing a problem when I search "main" in the memory browser under 32-Bit Hex - TI Style. The first couple of sections in hexadecimal code, 0x00000000 through 0x00000020, remain uninitialized. It appears like this:
0x00000000 FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF
0x00000010 FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF
This will cause problems in future code that I run on the board if I do not resolve it. I have traced the problem to the linker file, "TMS570LS122xFlashLnk.cmd". In the Section Configuration, there is a section called".intvecs" that is not currently pointing to any code files.

.intvecs appears black in color, while the other sections are colored purple, this further tells me that something is wrong with it. I have been looking through my computer's files (Macintosh HD > Applications > ti > ccsv7 > ccs_base > arm) for files that contain the code for those eight hexadecimal lines, but I cannot find anything that helps.
Looking through the online manuals and reference guides for the board, I have found that .intvecs should contain something like this:
"; interrupt vectors
resetEntry:
0x00 b _c_int00
undefEntry:
0x04 b undefEntry
svcEntry:
0x08 b svcEntry
prefetchEntry:
0x0C b prefetchEntry 0x10 b _dabort 0x14 b phantomInterrupt 0x18 ldr pc,[pc,#-0x1b0] 0x1C ldr pc,[pc,#-0x1b0]"
I have been looking for a .c file that contains these, but I have yet to find one. Where can I find the file that contains what I need?
