Original question:

TMS320F280049: ADC calibration

CCS/TMS320F28377D: ADC calibration

MUSTAFA KAYA1

Part Number: TMS320F28377D
Other Parts Discussed in Thread: C2000WARE

Tool/software: Code Composer Studio

Hi,

I am using this part in debugger mode and for adc calibration, I found out in the following link that if we are working in debugging mode, we must call the Device_cal function in our code to be able to load the factory defined offset trim values.

The link for the question: https://e2e.ti.com/support/microcontrollers/c2000/f/171/t/701752

My question is: How can I find the address for the pointer where the device calibration function resides in memory for my part? Is it the same for all parts?

Best regards,

Musti

    Mustafa,

    Yes, this is not well documented.  The address can be found in the boot ROM source in C2000Ware.

    C:\ti\c2000\C2000Ware_2_01_00_00\libraries\boot_rom\f2837xd\revB\rom_sources\F2837x_bootROM\cpu01-bootROM\include\c1_bootrom.h

    For F2837xD devices:

    #define DEVICE_CAL_LOCATION 0x70280
    #define C1BROM_DEVCAL (void (*)(void))(DEVICE_CAL_LOCATION)

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

    Note that even when using the debugger, you can still do a device reset in CCS and run from there (e.g., jump-to-flash or jump-to-RAM bootmode).  The the bootloader will run the device CAL for you.

    Regards,

    David

    Hi Mustafa,

    Every part in the F2837xD family will have the same pointer address for Device_cal().  Pointer address for Device_cal() changes though per device family (i.e. - F2837xD has different Device_cal pointer address as F28004x or F2838x ).
