CCS/AWR1642: how to using Watchdog reset in AWR1642

Coonan

Part Number: AWR1642

Tool/software: Code Composer Studio

I refer watchdog test from path C：\ ti \ mmwave_sdk_02_00_00_04 \ packages \ ti \ drivers \ watchdog \ test \ xwr16xx. Replace main_mss.c into my project and choose option 2. Watchdog interrupt CPU test.

Yes, the Reset LED will lighted after running debug mode on AWR1642EVM borad and I set breakpoint in watchdogCallback function the program will stop at breakpoint. That i think the watchdog is working correctly.

I try to add watchdog config function into main_mss.c in my project (short range radar SDK), however i observe the watchdog is not run and LED is not lighted. but error log is Feature: Watchdog testing: Passed

My question is I have already put the same watchdog config in my project. but it didn't work?

Hi Jitendra,

I got some question after i did experiment by the link(https://e2e.ti.com/support/tools/ccs/f/81/t/835932).

1. I follow the sample code set the watchdog config as below. If i want to stop program at function (MmwDemo_TimerCallBack) by set breakpoint in ccs debudg mode. I need add coding inside the red box. but sample code config resetMode is Watchdog_RESET_ON why i need change resetMode into Watchdog_RESET_OFF or i don't need to chang resetMode ?

2. How can i test watchdog reset awr1642 in ccs debug mode on awr1642 boost ?

3. when i use the sample code(https://e2e.ti.com/support/tools/ccs/f/81/t/835932) i find some thing weird. I can't suspend dss in debug mode.

Console box shoe some log as below.

Hi,

If you trying to do the debug from CCS then you need to set resetmode to Watchdog_RESET_OFF so watchdog doesn't reset the device.

If it does that you won't be able to connect to DSS, as during the Watchdog reset (warm reset) DSS goes back into reset mode (halted), thus can't connect from CCS.
