CC3200-LAUNCHXL: Impossible to flash CC3200

Part Number: CC3200-LAUNCHXL

Hi everybody, I have a problem with my CC3200-LAUNCHXL board. It became impossible to flash it with Energia IDE (I get the "failed to trigger bootloader" message), Uniflash, or debug it with CCS. I think it is an hardware problem, considering that with the same SW setup I can flash another identical board with no problems. I also performed a measurement of DCDC_ANA_SW and DCDC_DIG_SW voltages shown in yellow and blue in the oscilloscope picture attached below. In white the related voltages on the functioning board.

I had the same problem with a previous board (see https://e2e.ti.com/support/wireless_connectivity/simplelink_wifi_cc31xx_cc32xx/f/968/p/512811/1862480), which has been replaced by TI with this one. Now the same problem again after about 18 months. Is there the possibility to have another replacement board?

Thanks

Simone Riccardi

    Hi Simone,

    The oscilloscope picture doesn't seem to have attached properly, or I just cannot access it. Would you mind trying to include once more? Was there a particular event that triggered the the device to stop working? Even though it cannot be flashed, does the last program loaded to the device still run?

    Simone -
    can you confirm which version of Energia you are using and if you installed the board support package as described here?

    Hi Josh, I use Energia 0101E0017. I know newer version is available, but as already stated the board worked properly until last week. Moreover, another identical board works fine with the same IDE.

    Anyway, yesterday at first attempt I managed to flash the board both with Energia and Uniflash and the microcontroller seemed to work. Also I probed the voltages with oscilloscope and they were more or less the same of the functioning board (the delay between switching pulses was a bit greater on the defective board). But the chip on the defective board soon became hotter than the other one: I don't have a temperature probe, but with the tip of my finger I could feel a clear difference.

    The board run properly for about one hour after which stopped working. Soon the Microcontroller temperature started to drop reaching more or less the same temperature of functioning board. Then I tried to flash again the board, without success.
