    stack allocation fails in bmp3.c on ti-rtos

    stack allocation fails in bmp3.c on ti-rtos

    I am integrating the BMP3 driver (https://github.com/BoschSensortec/BMP3-Sensor-API) intn a TI-RTOS project.

    The code in bmp3.c allocates variable-length arrays on the stack in bmp_set_regs and bmp_get_regs and this fails. I think the failure is of the ARM C compiler, not something related to TI-RTOS. Possibly the issue is the lack of heap (not even sure if my project is configured with or without a heap, I certainly do not use malloc).

    Any advice? Thanks, Sivan

    Hi stoledo,

    Do you mean your error appeared in the folloing line on your platform?
    uint8_t temp_buff[len * 2];

    Yes, exactly.

    And also in

    uint8_t temp_buff[len + dev->dummy_byte];

    Hi stoledo,

    As your software environment didn't support this type of memory allocation, you could define a global array.
