[T5000][R__._] RTC clock resets after power cycle – suspected erratum RTC-1 / PCN 213441 (pre-PCN module)

Hi NVIDIA team,

We are experiencing RTC date/time loss on our Jetson T5000 module and believe it is caused by erratum RTC-1 in Jetson Thor Modules Hardware Errata DA-12711-001_v02, addressed by PCN 213441.

Module: Jetson T5000, OPN 900-13834-0080-000, pre-PCN213441 revision

Symptom:
After the system time is set, it is kept across some reboots, but after further power cycles or an abnormal shutdown the RTC loses the date/time and the system comes up with an incorrect (reset) date. This matches the RTC-1 description of the PMIC RTC failing to retain date and time over a power cycle.

Diagnostics attached:

  • cat /etc/nv_boot_control.conf (module revision)
  • cat /etc/nv_tegra_release (Jetson Linux version)
  • sudo hwclock -r and ls -l /dev/rtc*
  • sudo dmesg | grep -i rtc

Request:

  1. Please confirm this issue is caused by erratum RTC-1 / PCN 213441.
  2. Please confirm the module is eligible for replacement with the updated revision, so our distributor can process the RMA.

Thank you.

Hi,

Some questions to confirm:
Are you using a devkit or a custom board?

Thanks

It is a standalone production module (System-on-Module), not a complete Developer Kit.
