HI yuan,

There is only an R5 version of the SDK publicly available

https://www.ti.com/tool/download/CC33XX-RTOS-MCU

From this E2E

https://e2e.ti.com/support/wireless-connectivity/wi-fi-group/wifi/f/wi-fi-forum/1457360/cc3301-r6-version-wifi-fw-stuck-issue

the issue cannot be recreated. Could you take full logs of the crash using the logging tool found in the wifi toolbox in order to understand the issue that you are seeing.
