Tool/software:
Hi,
We are using a custom board based on am62x SK and using BQ32000 RTC with Super Capacitor as Backup.
After updating linux system time with date command and updating RTC with hwclock command. After couple of hours i did a powercycle.
After powercycle I found that time is not getting updated from RTC.
After looking e2e tickets came to know that Need to set TCFE bit to 1, This bypass internal diode to charge the super capacitor.
In drivers/rtc/rtc-bq32k.c i found bq32k_sysfs_store_tricklecharge_bypass function that updates TCFE bit from Linux userspace using /sys/ filesystem.
May i know the exact location/name of sys file need to used.
Is there other ways to update TCFE bit.
