Hi,

I am on 8.0 SDK & I am pretty sure 7.3 also will be triggering WDG reset correctly.

Here is the log:

HI Keerthy

I can reboot with Ti EVM board. SOC_SAFETY_ERRORN pin can change from high to low .

But I use Customer boards. I use oscilloscope to measure tda4 (U4) SOC_SAFETY_ERRORN pin did not change from high to low.

Thank you

In customer design, how is SAFETY_ERRN pin connected?

SOC_SAFETY_ERRORN connect to pmic gpio3, pmic is PTPS65941212RWERQ1.

In addition, the PMIC gpio3 is disconnected and does not change from high to low

PMIC part number PTPS65941212RWERQ1 is used in PDN-0B. GPIO3 for PMIC-A is programmed as output for MCU3V3EN. I believe PDN-0C uses GPIO3 as SAFETY_ERRn, but that has different PMIC part number (PTPS65941213RWERQ1).

Is that this issue - both PMIC and TDA4VM are driving output as outputs?

HI Robert

SAFETY_ Errn disconnects from PMIC, SOC safety_ Errn as output still cannot have high and low changes.

TI__Guru 52525 points

Ok - if SAFETY_ERRn pin isolated from PMIC, not much else to check-out on hardware. Looping in software help to investigate device configuration.

Hello,

Can you share the output of the below commands on your custom board:

cd /opt/ltp/
./runltp -P j721e-idk-gw -f ddt/wdt_test -s "WDT_M_FUNC_WRI"

I hope your custom board dtb has the watchdog nodes as well.

Best Regards,
Keerthy

When I ran the test case It rebooted around 30 seconds. Seems like you are getting an event around that but reset is not happening.

I can reboot with Ti EVM board. SOC_SAFETY_ERRORN pin can change from high to low .

But I use Customer boards. I use oscilloscope to measure tda4 (U4) SOC_SAFETY_ERRORN pin did not change from high to low.

From hardware perspective - I'm not aware what could be causing SOC_SAFETY_ERRONn to behave differently. We've already discussed the PMIC issue, but when isolated from PMIC - still does not behave same as EVM.
