LAUNCHXL-CC26X2R1: Communication Issue After Erasing Entire Flash on CC26X2R1 Using WBMS SDK

Part Number: LAUNCHXL-CC26X2R1

Tool/software:

Hello,

I am currently analyzing the wmain_diag and wdevice examples provided in the SimpleLink WBMS SDK (simplelink_wbms_sdk_2_00_03_09_eng). The development board I am using is the CC26X2R1.

While working on these examples, I accidentally clicked "Erase Entire Flash" in CCS, and after that, the communication between devices stopped working. It was functioning perfectly before this.

Here are some additional details:

  • I re-flashed both examples (wmain_diag and wdevice) after the flash erase, but the communication issue persists.
  • I attempted to reset and debug the board multiple times without success.
  • The SDK version being used is SimpleLink WBMS SDK 2.00.03.09_eng.

Could you please help me identify the cause of this issue and suggest how to restore the board to its previous working state?

Thank you for your assistance!

Best regards,

    Hi 

    simplelink_wbms_sdk_2_00_03_09_eng is an very old version of SDK. Would you please upgrade to the latest one? 

    Regarding your issue. I wonder if you are using Manual Network Start or Automotive and the size of the network. By default in the old SDK version, the network size is 8 WDs and automotive network start, which means you will need enough WDs to get the network run. There is guidance in UG in SDK which tells how to change the network size.

    Best Regards,
