warning: creating output section ".adc_cal" without a SECTIONS specification

Hi Thomas

Somewhere in the code you assign a variable to the section .adc_cal, however this section is not defined in the linker cmd file (usually the command file for flash configuration is different than for ram configuration). So you either assign the variable to another section or you define the section in the command file, and the warning should be gone away.

Best regards

Andreas

Hello ,

I have the same problem exactly.

Code Composer shows me the warning: 

"warning: creating output section ".adc_cal" without a SECTIONS specification" and the code is halted in the first execution of ADC_CAL (at begginning code).

¿Do you solve this problem?

Thanks and regards,

Ivan

if you are using matlab, double click the Target Preference block in your model. the second tab shows all defined memory tags. the last one is ADC_CAL which points to 0x380080 with a length of 0x09. The next tab is section, notice there is a .adc_cal needs to be placed to ADC_CAL section. 

Hi Leong,

Thanks for replying but I configure Target Preferences block in the same way and it isn´t working.

Have you got that works correctly standalone including any ADC?

I'm using 2010b and I chose the 28335 custom board. I had it worked fine with my ADC. The setup I have is a 28335 usb docking station+control card. In matlab i do ccs4 makefile only for now and i load the program directly from the ccs4 debugger.

if you are using ccs4, It may also help if you create a separate CCS4 project and import all -Ds from the rtwproj. then link all source files and add necessary path to the project. After the RTW build, you can compile the separate project in CCS4. Then you can hand modify some code and see the effect.

ps. below is the cmd file i got.

Hi Leong,

my cmd. file looks exactly the same but I haven´t got that it works.

Questions:

1. When you said " import all -Ds from the rtwproj", which files do you import? Could you list them please? CCS4 doesn´t build me the project without errors...
2. Must I hand-modify a lot of code?

Thanks again, I appreciate very much your help!

Hi tomas,

I have similar problem and I solved this by restarting the CCS. Hope it helps.  :D
