I am trying to debug code that was written by someone else on a TMS320C6713B DSP.
As a debug test, I set cal.vab = 0.0. When I run in debug mode, instead of reaching the breakpoint, there is the following message, "Break at address "0xc5ec" with no debug information available, or outside of program code". When I try to access the value of cal.vab in Expressions, it results in an arbitrary float of 1.058..e-37
There are two possible issues that I think could explain why the problem exists:
1) When I go to Debug Configurations -> Source, the program shows the following: "Device Library Source - no 'src' folder for TMS320C6713". I tried to add the path/directory to the TMS320C6713 library file, but the Edit button is greyed out.
2) The project uses a custom Boot.cmd file, in which "vecs" and "boot" are added in memory. This could cause some type of boot error, or memory error in the debugger.
Boot.cmd:
MEMORY
{
vecs: o = 00000000h l = 00000200h
boot: o = 00000200h l = 00000200h
IRAM: o = 00000600h l = 0000FA00h
CE0: o = 80000000h l = 01000000h
}
SECTIONS
{
"vectors" > vecs
"bootload" > boot
.cinit > IRAM
.text > IRAM
.stack > IRAM
.bss > IRAM
.const > IRAM
.data > IRAM
.far > IRAM
.switch > IRAM
.sysmem > IRAM
.tables > IRAM
.cio > IRAM
}
"vectors" and "bootload" are defined in the file bootMICKAELModified.asm which is copied below.
I have tried the following:
1) manually loading debugging symbols via Load -> Load Symbols
2) setting the compiler optimization level to 0.
Thank you for your help. I am in the process of learning about Boot files and .cmd to see if I can figure out the issue myself.
