Code not running with CCS6 but runs fine with CCS5...

Hi all,

I need your help with this one. I have a project that is running just fine with CCS5. WhenI try to run it in the debugger in CCS6, it does not seems to start. I can't step in main. The only difference I can see in related to the cmd file.

Here is the cmd file from CCS5:

MEMORY

The difference is in the SECTIONS section related to definition of interrupts. Maybe it is the reason?

Also, in CCS5, I have the output format set to Legacy COFF but in CCS6 it is set to eabi (ELF).

Maybe it might explain why it is not running?

Any advice on what could cause the code to not run in CCS6? I'm not sure which info to provide you to get good help...

Thanks

I forgot to mention. The compiler version in CCS6 is TI v15.12.1.LTS

The TI v15.x series of compilers have removed support for Legacy COFF, which is why CCS 6 with TI v15.12.1.LTS the output format was set to eabi (ELF). Changing from legacy COFF to eabi (ELF) for MSP430 programs may cause the following issues for project:

1) In eabi (ELF) the .bss segment is zero-initialized by the C run-time library startup, which may mean the WDT fires during C startup code

2) In legacy COFF double is 32-bits, and in abi (ELF) double is 64-bits. If a program uses any implicit or explicit double calculations that can increases the code and data memory usage.

If you won't want to have to modify the project to work with the eabi (ELF) output format, you should be able to install the same compiler version in CCS 6 as was used in CCS 5 - see http://processors.wiki.ti.com/index.php/Compiler_Updates#Install_new_features and http://processors.wiki.ti.com/index.php/Updating_CCSv6#Installing_new_software

Thanks a lot for the info, I'm going to give it a try.
I don't think double calculation is a problem, but .bss segment to zero could be my issue.
I'll keep you posted!

Unfortunately, it did not help.

1. I did validated that watchdog is on hold during cinit auto-initialization. The option was already ON.
2. I validated that I'm not bumping any boundaries in FLASH and RAM... The Memory Allocation window provide good help on that. Everything seems OK.
3. I removed any call to driverlib to prevent any oversized functions...
4. I changed Silicon version from mspx to msp... I think the MSP430F5419A does supports mspx, but it was worth trying... It's now back to mspx.
5. The heap and stack size is set to 2048. Could it be the reason?

The code is still not hitting main function... any help is welcome!

Thanks.

Since you mentioned changes to linker command files, do you get any warnings from the linker of the form "Warning: creating output section "xxx" without a SECTIONS specification"?

Such warnings are a sign the program may fail at run time, e.g. the linker may have defaulted to placing some variables in peripheral address space rather than RAM!

If you want to try and determine why the program is not reaching main, under the CCS project properties -> Debug -> Auto Run and Launch Options -> Auto Run Options untick the options to run to main for either "On a program load or restart" or "On a reset". When you start a debugging session the program will be halted at the reset vector, and you can single step through the run time library start-up code to find at which point the program fails.

I have a project that is running just fine with CCS5. WhenI try to run it in the debugger in CCS6, it does not seems to start.

If you don't need to change the project in CCS 6, one option would be start a Manual launch of the debugger in CCS 6 and then download and debug the program which was built in CCS 5.

Thanks for the suggestion.

Using your tips, the program started at 0x5c00, which according to my cmd file is PLATFORM_INFO_0.

I end up stepping in disassembly since there is no symbols for that. My understanding is that it's not right to step there at startup. Am I right?

The address 0x5c00 is the lowest flash address in a MSP430F5419A, and so based upon your linker command file agree that is not correct - the run time library entry point in the .text:_isr section should be in the FIRMWARE_INTERRUPT_FCT memory region from 0x9C00 to 0xBBFF.

Can you check the linker .map file to ensure the linker is using the memory regions in the linker command file?

In the cmd file, I have:

FIRMWARE_INTERRUPT_FCT  : origin = 0x9C00, length = 0x2000 // so from 0x9c00 to 0xbc00
.text:_isr : {} > FIRMWARE_INTERRUPT_FCT              /* ISR CODE SPACE                    */
.cinit     : {} > FIRMWARE_INTERRUPT_FCT              /* INITIALIZATION TABLES             */
.pinit     : {} > FIRMWARE_INTERRUPT_FCT              /* C++ CONSTRUCTOR TABLES            */
.function_pointer:{} > FIRMWARE_INTERRUPT_FCT

(note that pinit is in cmd file and not in map file, I guess it's because I don't have any c++ code...)

In map file, I find the following:

All sections are inside the desired area. They are not in the expected order, but they are in the good area.

I'm looking at the entire file and it seems ok to me up to now.

That is the entry point for the C run time library, and so when you start debugging without auto to main enabled I would expect the initial program counter to be 0xa552 and not the 0x5c00 value you found.

Can you post the complete map file, .out file and/or build output from the CCS console?

Yes, I'm going to post it. But you know what... I'm suspecting my code to not beging uploaded... I've just uploaded a simple blinking LED program and then I try to debug my "not working" program. The debugger indicates me it's running (but not stepping in main like always), but the LED is still blinking... which is not the case in this program.

The Erase Options seems right to me (Erase main memory only).

Is there another option to look at to make sure my program is being written to the flash?

Well... I successfully stepped into my code and it seems to work...... when it is uploaded.
I don't understand why, but CCS does not upload my code into the MCU when I start a debug session.
To have it uploaded, I have to select "Run/Load/Load Program" and then it gets uploaded....

Any idea how to change that annoying behavior?

By the way, thank you very much for your help/efforts. It is greatly appreciated.

I finally found it...
Under "Run/Debug Configuration"
I selected my program configuration, then the tab named "Program".
I dont' know why, but the "Load symbols only" was selected. I changed it to "Load Program" and now it works.

That is a mistery how this value got changed... Anyway, thanks for your help!
