Hi:

       I  try to port CC3120MOD drive to STM32, the platform is STM32 + KEIL + FREERTOS9.0. when I start the sl_start()，return -2005,

I debug my program by step , I found  when go into the sl_start() ，MCU send data 08 00 76 D0 to CC3120 by SPI ,and next MCU read data

20 00 54 F8 and next MCU read data 20 00 54 FC again,  the next the sl_star()return -2005, please give me some suggestion about this question.

thank you very much.

    Hi,

    It looks like you have some issue with the SPI.

    The values you mentioned are not as expected and thus the SYNC_LOSS error.
