Flashing CC2650STK using SmartRF Flash Programmer 2

Other Parts Discussed in Thread: CC2650STK, CC2640, UNIFLASH

Hi,

1. I am trying to flash CC2650STK (SensorTag V2) via CC-DEBUG-DEVPACK using Flash-Programmer-2.

2. I get this error:
    "Connecting over serial bootloader failed.
    Device may not be in bootloader mode.
    Reset device and try again".

3. For any case:
    I did loaded the BIM project onto CC2650STK with CCS.
    I did press the "select' button during powerup (USB power off & on).

4. What is the way to flash the CC2650STK ?

Thanks,
Shlomi.S

    Hi,

    If you flashed the BIM, you'll need to follow the unbricking procedure in the CC2640 FAQ thread at the top of the forum. You should just need to build & flash the Sensor Tag App/Stack images that are built with CCS or IAR.

    Best wishes

    Hi,

    1. Clearly, the Flash-Programmer-2 is not communicating with the SensorTag.
        It is a UART communication.
        It is not related to BIM.

    2. The communication program is a built-in ROM program; called ROM-based bootloader.
        This is in TRM 9.1.

    3. It may not working because of CCFG.
        However, the ccfg.c is set correctly to "#define SET_CCFG_BL_CONFIG_BOOTLOADER_ENABLE 0xC5 // Enable".

    4. Simply put:
        1. How can I use Flash-Programmer-2 with CC2650STK (with XDS110 devPack) ?
        2. How can I program any HEX file to SensorTag-2 ?

    Thanks,
    Shlomi.S

    Hi Shlomi,

    The XDS110 currently uses regular 4-pin JTAG but it seems Flash Programmer 2 is a bit confused here. The CC Devpack Debug does not support UART.
    We have notified the tools team which will look at it. You can try to use the TI Uniflash tool in the mean time which should support the debugger.

    Hi,

    You need to download the SmartRF Flash Programmer 2 v1.6.0 or higher to get XDS110 support (CC-DEVPACK-DEBUG).

    You can download SmartRF Flash Programmer 2 here:

    Edit: The reason why the XDS110 shows up in SmartRF Flash Programmer 2 v1.5.0 is because it enumerates as a COM port.
