Original question:

CC3120: CC3120 sl_stop() fails after Wi-Fi FATAL error due to SYNC loss event

CC3120: FATAL ERROR: Sync loss detected #012#015

Part Number: CC3120

We are using the CC3120 in our product. After some time from powering up the device the wifi application repeatedly crashes with the following error:

wifi_bridge_log[15626]: [ERROR] -  FATAL ERROR: Sync loss detected #012#015

wifi_bridge_log[15626]: [NOTICE] - Exit Program

The application crashes about 4 minutes after the OS has restarted it, repeatedly.

We are using the simplelink_cc32xx_sdk_7_10_00_13 driver.

Any hints on what can cause this? Thanks.

    Hi,

    Commonly this type of issues mean problem with physical communication with CC3120 (e.g. SPI). Or it can be something else inside your host code like stack overflow.

    Capturing NWP log from CC3120 may to eliminate hypothesis that issue is at CC3120 itself.
