  • [ABANDONED] unions with structs dont display properly

    union with struct overlaying with U32 & array of 2 U16
    U32 & 2 U16s show ok
    struct doesn't but all show as the same address [ as you would expect ]

    typedef union
    {
    struct
    {
    uint32_t PowerEnable : 1;
    uint32_t Startup : 1;
    uint32_t Fault : 1;
    uint32_t HwFault : 1;

    uint32_t Present : 1;
    uint32_t xExpanderPresent : 1;
    uint32_t xExpanderOk: 1;
    uint32_t : 1;
    uint32_t xChargerPresent : 1;
    uint32_t xChargerOk : 1;
    uint32_t SmartBattPresent : 1;
    uint32_t SmartBattOk : 1;
    uint32_t : 4;

    uint32_t HwFaultShadow : 1;
    uint32_t Updated : 1;
    uint32_t Channel : 1;
    } ;

    uint16_t aU16[2];
    } UnBatteryStatusReg;

  • Hello,

    Thank you for your inquiry.
    Which version of Ozone are you using exactly?
    Do you see the same issue in the latest version?

    typedef union
    {
    struct
    {
    uint32_t SldEn : 1;
    uint32_t TecEn : 1;
    uint32_t IntegrationCap : 1;
    uint32_t : 1;
    uint32_t SaveCal : 1;
    uint32_t LoadCal : 1;
    uint32_t LoadCalToSystem: 1;
    uint32_t RebootFpga : 1;

    uint32_t StopAnMux : 8;
    uint32_t EraseFgpaFirmware1 : 8;
    uint32_t EraseFgpaFirmware2 : 8;
    };
    uint32_t U32;
    } UnControlReg;

    you can see in the picture the bottom 2 bits are set in the U32 but you dont display any of the struct values

  • Ok now I am confused.
    I ask if the issue is in the latest version and you write no. Yet you post a reproducer.
    I assume this is not resolved yet, correct?

    We will check if the issue is reproducible and report back with our findings.

  • Hello,

    The reported behaviour is not reproducible for me with Ozone V3.26h, see picture attached.
    Could you provide an example project for reproduction that would run on an eval board?
    An elf file + the Ozone project .jdebug file should be sufficent.

    Best regards,

  • Hello,

    Unfortunately this is not helping.
    We would need to reproduce the behaviour on hardware.
    Could you provide an example project for reproduction that would run on an eval board?
    An elf file + the Ozone project .jdebug file should be sufficent.

  • how do I know what boards you have ?

    this elf file is for a samd20J17

    it won't run on any hardware you have but you can find the "Registers" global object to find a bunch of examples of those structures

    This should not matter. This is a pure software issue and should be target independent, correct?
    So if you could provide us with an reproduction project that could run on any Arm Cortex-M eval board that would be helpful.
    We have over 3500 evalboards in house so there is a good chance that we already have it. If not we will get it.

    Ok good. We have e.g. the SAM D20 Xplained Pro in house.

    We would need a project that could run on an evalboard. A simple stripped down project that shows this behaviour would be sufficient.
    Could you provide this?
    Please understand that the time we can spend on investigations is very limited which is why it is a requirement that in case of bug reports a universal reproduction setup is provided as we can't spend an undefined amount of time on trial and error without guarantee for success.

  • well just download it, find the instance of the structure and just change the U32 / memory fundamental value . that is all you need to show the issue as "Registers" is a global static variable with the union structs inside it
