Hello Team,
We had a session with the PMIC team yesterday and we were able to set the WD_EN bit to low and then later EN_DRV bit using the I2C2ANY tool.
But when i tried to disable the WD_EN using the Pmic_wdgDisable() function, it is throwing a negative response.
The debugger is failing to point out the exact point when i tried to step through the code, but the debugger control is lost in Pmic_commIntf_sendByte() --> I2c_transfer() function call, from where the negative response is thrown. The error code is not a valid one for the I2c code.
I tried to use the Pmic_wdgSetCfg() to modify the failure threshold count to 6, but it is also throwing a negative response.
On the other hand, the Pmic_wdgGetCfg() is functioning properly.
Can you please help me understand the root cause of the issue ?
More Updates:
I have also tried to run the WDG test app example with limited tests to execute, but it had stopped in initialization test and none of the WDG related tests is executed.
