Provisioning AP Example CC3100 Stack Size

Other Parts Discussed in Thread: MSP430FR5969

What should the stack size be for running the Provisioning AP example? I had to set it to 500 to run the email example, but now I get a program will not fit error.


Here is the error:

"../lnk_msp430fr5969.cmd", line 174: error #10099-D: program will not fit into available memory.  run placement with alignment fails for section ".stack" size 0xc8 .  Available memory ranges:
   RAM          size: 0x800        unused: 0x15         max hole: 0x15

If I set the stack size down to the incredibly small size of 0x14, the program gets hung up, but that's the only way I can get the example to compile.

Thanks.

    Hi Salvatorre,

    We haven't tried the provisioning AP example on MSP430FR5969 platform.
    You can try optimizing the application to fit into the available memory. I suggest to comment the 'configureSimpleLinkToDefaultState()' function call and definition. With this stack size of 500 should be good enough.

    Please let us know if this works.

    Regards,

    Thanks for helping me with the stack size, Ankur. I got it working! There are probably more eloquent ways of doing it, but in the map file I saw that I had plenty of FRAM and almost no RAM. In the command file I set .bss to be placed in FRAM instead of RAM. I'm sure if you worked to reduce global and static variables, you could keep .bss in RAM.
