    Ravi,

    Few things to check here:

    1) When you power the LP with USB, does D2 turn on? This indicates that the TM4C is functional. 

    2) Is the SOP configured as 010 to boot the device in flash mode?

    3) At most, you must short the headers shown below to connect to UniFlash via UART

    Hope this helps,

    Seong

    I did SOP configuration as (100) and after that it is connected.But after following all the steps given () in this pdf ,TERA TERM  throws error "Network Terminal - Couldn't configure Network Processor - -4110".

    Ravi,

    The different boot modes and SOP functional configs are explained in Section 6.8 of the CC3220's datasheet. Here you'll note that SOP config 100 will boot the device in UARTLOAD mode. While you're able to use UART to program the serial flash, the SOP bits must be toggled to configure the device in functional mode.

    I suggest that you keep the SOP config as 010 when experimenting, which will boot the device in UARTLOAD/FUNCTIONAL/4WJTAG mode. This way, the device will run the network-terminal example immediately after you program the flash.

    Refer to Table 6-6 to learn about the other types of functional modes. And note that you cannot switch between different boot modes while the device is powered. Remember to configure your SOP and reset the device to boot it in the desired mode.

    The error 4110 does refer to a failure of calibration as defined in errors.h from the SDK. If you've already tried what I mentioned above..

    1) Please confirm if you are experimenting with a CC3220SF Launchpad or your own custom board.

    2) What version of the SDK and servicepack are you using? The latest can be downloaded here.

    3) How are you powering the device? The peak calibration current can range from 420mA~700mA depending on VBAT.

    4) Do you have any other devices around? RF interference could cause calibration failing on sl_Start().

    On a separate note, a more current version of the Getting Started Guide is the "Wi-Fi Fundamentals" Lab from our SimpleLink Academy.
