CCS/CC3120BOOST: Sync loss error debugging

Part Number: CC3120BOOST
Other Parts Discussed in Thread: MSP430FR6047, CC3120, UNIFLASH

Tool/software: Code Composer Studio

I am trying to use the cc3120 booster pack to add internet to my msp430fr6047 (EVM430-6047). I configured my spi and gpio pins and ported the latest sdk to work with my board. I am using TI RTOS and CCS to build my code. I was able to successfully start the device in station mode using the sl_Start() api. However, any other api I call subsequently gives me a fatal "Sync loss error" following which nothing works. Trying to use the sl_Stop() and restart using sl_Start() fails to bring it back to station mode. The sdk version i am using is 2_40_00_22. Please suggest me ways to debug this issue.

    Hi Jaya,

    This is a known issue with our cc3x2x host driver. I would suggest downloading the latest CC32XX SDK to use that host driver instead.

    Hello Jesu,

    I have updated the cc3120 boosterpack with the latest service pack using the Uniflash. I am able to start the device in Station role, a wlan event is getting generated as below:

    [Event] STA connected to AP - BSSID:48:xx:xx:xx:xx:xx, SSID:FiOS-xxxx (I intentionally removed the letters and replaced with 'x' here)

    [ERROR] - FATAL ERROR: Sync loss detected

    In some of the restarts I advanced one step forward as below (this ip address acquisition is only sporadic, I cant consistently get to this step):

    [NETAPP EVENT] IP Acquired: IP=192.0.168.0 , Gateway=1.0.21.0

    [ERROR] - FATAL ERROR: Sync loss detected

    Here, the Ip address should be 192.168.1.21, however, it looks like there is a shift happening. Would you be able to give me some clues on how to debug this. 

    Thank you!

    Hi Jaya,

    It is difficult to know what could be going wrong since you're using MSP430. Please keep in mind we don't have SW that natively supports MSP4320 on CC3120. My suggestion to you is you upgrade from MSP430 to MSP432 because everything will work out of the box.
