Error in breakpoints when debugging CC2540 using IAR

Other Parts Discussed in Thread: CC2540, CC2541

Hi,

I came across the attached post when trying to figure out why, when stepping through breakpoints with the CC Debugger, I keep on getting the message: "Unable to execute: driver error". Every time this happens IAR workbench freezes and I need to force quit. This poster seems to be having the same problem without any resolution. Any ideas on what could be causing this?

Thanks,

Matt

    Hi Matt,

    I am suspecting it might be because of some legacy code in the BLE stack, I have seen this issue in other code where IAR / CC Debugger freezes during the code sequence changing from the internal 16MHz RCOSC to the external 32MHz XOSC when single-stepping through this with IAR.

    Can you verify if the following helps in your case? :

    hal_board_cfg.h:

    Remove the following macros:

    START_HSOSC_XOSC(); \
    SET_OSC_TO_HSOSC(); \
    STOP_HSOSC(); \

     Example:

     

    /* Board Initialization */
    #define HAL_BOARD_INIT() \
    { \
    /* Set to 16Mhz to set 32kHz OSC, then back to 32MHz */ \
    SET_32KHZ_OSC(); \
    SET_OSC_TO_XOSC(); \
    /* Enable cache prefetch mode. */ \
    PREFETCH_ENABLE(); \
    }

    Best regards,
    Svend

    I have the same issue when debugging the cc2540 chip and running the HIDAdvRemoteDongle project.  However, in removing those lines (I removed 6 lines because it appeared in two places) I still receive this error.  

    It now appears:

    /* Board Initialization */
    #if defined HAL_USB_BOOT_CODE
    #define HAL_BOARD_INIT() \
    { \
    /* Set to 16Mhz to set 32kHz OSC, then back to 32MHz */ \
    SET_32KHZ_OSC(); \
    STOP_HSOSC(); \
    \
    /* Disconnect D+ signal to host. */ \
    HAL_USB_PULLUP_DISABLE(); \
    \
    /* Enable cache prefetch mode. */ \
    PREFETCH_ENABLE(); \
    }

    #else
    #define HAL_BOARD_INIT() \
    { \
    /* Set to 16Mhz to set 32kHz OSC, then back to 32MHz */ \
    SET_32KHZ_OSC(); \
    SET_OSC_TO_XOSC(); \
    \
    /* Enable cache prefetch mode. */ \
    PREFETCH_ENABLE(); \
    }
    #endif

    sorry, correction, it now looks like this:

    /* Board Initialization */
    #if defined HAL_USB_BOOT_CODE
    #define HAL_BOARD_INIT() \
    { \
    /* Set to 16Mhz to set 32kHz OSC, then back to 32MHz */ \
    SET_32KHZ_OSC(); \
    SET_OSC_TO_XOSC(); \
    \
    /* Disconnect D+ signal to host. */ \
    HAL_USB_PULLUP_DISABLE(); \
    \
    /* Enable cache prefetch mode. */ \
    PREFETCH_ENABLE(); \
    }

    #else
    #define HAL_BOARD_INIT() \
    { \
    /* Set to 16Mhz to set 32kHz OSC, then back to 32MHz */ \
    SET_32KHZ_OSC(); \
    SET_OSC_TO_XOSC(); \
    \
    /* Enable cache prefetch mode. */ \
    PREFETCH_ENABLE(); \
    }
    #endif

    Hi sved,

    I have the same issue of Matt, so I remove the macro in hal_board_cfg.h....and...... I still have the error.

    I use the SimpleBLEperiphical project from the stack 1.4 with IAR 8.30.3 and a custom board (a CC2541 with an another chip connected by I2C).

    Do you have any idea ? Something to check ? Modify ?

    Best regards,
