製品型番：AGX4500-U00Z

お世話になっております。
以下の条件で電源を投入した際に、時刻情報が時々初期化される現象が発生しています。
・12V電源を常時接続
・CON12の5pinで起動
・rtcwake -m no -s 3600 ⇒ poweroffのコマンドを記述したスクリプトでシステムを終了
起動時に時刻が正常な場合と、初期化される場合があります。
詳細な検証はできていませんが、poweroff後数十秒以内であれば時刻は保持され、数分経過すると初期化されるように見えます。
失敗の際は、setup_rtc_disarm_alarm: Can't find device id=0x32とブート時に出ていますので、初期設定に失敗しているように見受けられます。
※BaseOSのイメージは、HPからダウンロードした「baseos-x2-installer-3.20.3-at.7」をそのまま使用しています。
原因について、わかるようでしたらお教えいただきたいです。
よろしくお願いします。

コイン電池の使用は想定していません。
今回、搭載Appの更新に加えて、BaseOSを3.18.5-at.8⇒3.20.3-at.7に変更しています。
同じ基板で、以前は主電源系のみの接続状態で、1時間おきに定期的にウェイクアップし、dateコマンドで正常な時刻が更新されていることを確認していますので、RTCは主電源接続状態であればRTCウェイクアップ可能な認識です。（認識が異なりましたら、ご指摘お願いします。）
ログの内容から、問題の想定は可能でしょうか？
※本問題に関する不具合が、OSの更新に依存しているかどうかは引き続き検証します。

はい、それは理解しています。条件確認のためコイン電池使用で変化するかを確認したかったのです。

HW設計に確認したところ現状、poweroff状態では12Vが入っていてもRTCへの電源系が
内部的に遮断されるので、内部のコンデンサ分（40秒程度）を超えるとRTCがリセットされる設計となっています。
現状poweroffまで落としてしまうと、コイン電池非搭載の場合RTCの時刻を喪失します。
これは、2025年後半(出荷状況によって前後します)出荷製品で変更され12V系から直接供給の設計に変更予定です。
コイン電池を利用いただくか、Suspend-to-RAM/Suspend-to-Idleであれば、コイン電池なしでもRTCが維持されるので
いずれかの方法で回避いただけると幸いです。
OSのソフトウェア的な挙動ではありません。

追記補足です。
rtcwakeを設定していますが、先ほどのログは双方ともに、poweroff後、CON12から起動しています。
数十秒以内であれば～の下りは、poweroff⇒CON12起動の間の時間です。
