CC3301: CC3301 - R7 Firmware, WLAN_EVENT_FW_CRASH after a scan request

Part Number: CC3301

Tool/software:

Hello, 

we have just updated from R5 to R7 our driver for the CC3301 but is seem to break what was working. 

The firmware upload properly but as soon as we request a scan we receive a WLAN_EVENT_FW_CRASH event.

I atteched the log output, it seem their is no crash message on it.

thanks for your support

  • Hi Julien,

    Are you using the network terminal example as is, or is this your own implementation?

    Can you upload the logger file in wireshark format, it is easier for us to analyze this way.

    If you have your own application, can you show us how you prep for a scan command?
