Hi,
It is a question of following eratta of AM5728.
i862:Reset Should Use PORz
There are following mentions by "Implementation 1" of this eratta.
The side effects/risks of this implementation include:
This implementation does not allow software to shut the PMIC outputs that which falls
Power the SoC.
Only the PMIC RESET_IN can shut the PMIC outputs while which falls
POWERHOLD is pulled high.
Does these "Implementation 1" support only RESET_IN in the list of Table 5-10 OFF Requests of the data sheet of TPS659037 ?
www.tij.co.jp/.../tps659037.pdf
In Table 14 Shutdown_ColdReset OTP Settings of the following documents, the value of RESET_in is cold reset
www.tij.co.jp/.../sliu011d.pdf
Can SW_RST of DEV_CTRL Register and the PWRDOWN pin input of TPS659037 shut down the system?
Best Regards,
