Other Parts Discussed in Thread: SK-AM62B
Hi Ti
开发环境：1）参考板:SK-AM62B，2）SDK ti-processor-sdk-linux-rt-am62xx-evm-08.06.00.42
遇到问题：我使用如下命令，更新RTC的值，从命令结果来看，是设置成功了，但我重启后，又回到了默认值
root@am62xx-evm:~# date -s "2023-10-26 14:45:00" Thu Oct 26 14:15:00 UTC 2023 root@am62xx-evm:~# hwclock -r 2023-02-24 04:55:58.577793+00:00 root@am62xx-evm:~# hwclock -w root@am62xx-evm:~# hwclock -r 2023-10-26 14:15:21.675057+00:00
问题分析：
（1）在设置和读取函数中，分别增加打印，如下

（2）重复以上的步骤
1）读取默认值

2）设置
root@am62xx-evm:~# hwclock --set --date="2023-10-26" [ 70.338796] rtc-ti-k3 2b1f0000.rtc: gjw ti_k3_rtc_set_time y123,m9,d26 [ 70.345406] rtc-ti-k3 2b1f0000.rtc: gjw ti_k3_rtc_read_time y123,m9,d26
3）检查确认成功后重启

Stopping Session c1 of user root.
4）重启后，发现又回到了默认值，根本就不是设置的值

需求帮助：
1）为什么每次起来，读到的是1970-01-01？？
2）怎么操作，才能让它启动时，读取我设置的RTC设置，而不是默认值
