    temperature values is always 0

    Re: temperature values is always 0

    Hi Minhwan,
     
    Due to this space issue, I have migrated to a higher flash chip which is a 32-bit ARM Cortex-M33 platform. Can anybody have tested on this platform?
     
    Could you support this flavour with the supported library? Instead of sharing could define the supported specific library for this platform.
     
    Because of your AQI chip we are migrating and creating the final product. could take this high priority and support on the library integration side?
     
    Now you are showing our interest, Please take this high priority and get the support from your development team.

    Hi Kumar, 

     

    Yes, we do have library for Cortex_M33. You can download it below path.

    https://www.bosch-sensortec.com/software-tools/software/bme688-software/

    And there is M33 library in below path folder. 

    BSEC_2.0.6.1_Generic_Release_04302021\algo\normal_version\bin\gcc\Cortex_M33

    Thank you.

    Hi Minhwan,

    Thanks for your response. But my platform compiler and flags are as below:

    arm-none-eabi-gcc -g3 -gdwarf-2 -mcpu=cortex-m33 -mthumb -T -mfpu=fpv5-sp-d16 -mfloat-abi=hard

    Any modifications please suggest to me. as per my compiler will your below link library will support? I believe you shared the library is not arm gcc right?

    Want to explore more, please clarify my doubts?

    Regards,

    Kumar

    Hi Minhwan,

    Update as per given libraray compiled for our Cortex-M33 platform and got the below error::

    ------------------------------------------------------------------------------------------------------------------------------------------------------------------

    c:/toolchains/gnu_arm/7.2_2017q4/bin/./../../../arm-none-eabi/bin/ld.exe: error: BME680_Algo.axf uses VFP register arguments, c:/toolchains/gnu_arm/7.2_2017q4/bin/../lib/gcc/arm-none-eabi/7.2.1/../../../../arm-none-eabi/lib\libalgobsec.a(bsec_codegen_do_steps.o) does not

    ------------------------------------------------------------------------------------------------------------------------------------------------------------------

    Please share it to your development team will guess what exactly the problem. I am suspectign given the libraray is not compatiable to our compiler flag.

    check and share the supported library?

    Regards,

    Kumar
