Trevor Hsu

Tool/software:

Regarding SDK(simplelink_cc32xx_sdk_7_10_00_13) examples(such as connection_manager, mqtt_client, mqtt_client_over_tls_1_3 ....), when change the optimization level from z to 0. an exception will occur as show in the following screenshot

Could you help to check this issue?

Thanks

Update root cause:

This issue is related to task overflow, in simplelink_cc32xx_sdk_7_10_00_13\source\ti\drivers\net\wifi\slnetif\slwificonn.c, it needs to change TIMER_TASK_STACK_SIZE from 256 to 512
