SIMPLELINK-CC13XX-CC26XX-SDK: Library disturbs tghe Ti CCS debugger



I am developping an application to collect data from sensors.

When I start the application and stop it immediately at a breakpoint I get the following stack in Ti CCS debugger

The stack is correct from SensorBme68X_open to dataRecordingTaskFxn which is one of the main tasks of the application.

However I do not understand the 2 occurances of the init_iaq_2nd_gen_ulp() which are related to an imported library for another sensor. 

This library has nothing to do here whithin that stack.

This library has been compiled by the sensor's supplyer using another developmement tool than Ti CCS (This library has been compiled with  arm-none-eabi-gcc.

I imported the .h and .a files as usual with TiCCCS.

Any idea why I get this strange behaviour ? And how  to solve it ?


  • Hello Frederic,

    0x10000000 is not a valid memory area for SimpleLink devices.  Have you successfully used this pre-built library with a SimpleLink product before?  Even while using a compatible arm-none-eabi-gcc version (9-2019-q4-major), if the sensor's supplier did not build the library for the SimpleLink SDK then it will not work on these devices.
