Part Number:AM4378
Tool/software: Linux
Dear,
We designed a board broadly based on AM4378-gp-evm and we use SDK4.02.
My problem is, RTC TIME got reset when i reboot the system.
I followed "RTC timer functionality but no RTC-only mode" from the below link. But when i disconnect "PMIC_POWER_EN" . i am not getting any PMIC output voltage. so i connected "PMIC_POWER_EN" (AM4378 side) to PMIC IC.
I set fseal bit in the PMIC ic. Now i am able to get DCDC-5 , DCDC-6 and PGOOD_BU even in power off condition also.
I set time as given below
date 100816452018 (date MMDDhhmmyyyy)
hwclock -w (for writing date)
hwclock -r (for reading time)
If i set time, it got set properly. But when i reset the system, i has gone to the old value.
How do i keep the time after reset the system?
Regards,
Winiston.P
